Oca in Ottawa?

 photo IMG_2208.jpg
Labelled and bagged oca (aren't I organized for once)

My first attempt to grow oca didn't work out so well but this time worked quite a bit better and was rather encouraging from a crop improvement perspective (not from a holy cow that's an awesome plant that could feed me perspective).

I received some tubers of a common variety called Sunset and another (though the critters scurried off with it) and some seeds. The seedlings look like a shiny sorrel:

Oxalis tuberosa seedlings

They are a popular novelty crop in maritime climates like England, west coast of America etc..* where they thrive in cool, misty weather over a long frost free season. The tubers, reported to taste like lemony potatoes, don't even begin to form until days shorten in fall but they are killed by frost. Reading that, I thought, "why heck yeah, I want to try that in Ottawa, Canada!"

Unhappily putting up with heat and sun.

Some common (though technically unseasonable) cold weather hastened my intended mid-November harvest to November 6. I had been covering them with plastic totes during the first frosts: Simple for a short row. So I pulled them and put them in bags and stored them - on the plants with soil - in the garage hoping to redirect some of the fleshy stem goodness to the tubers.

Storing in bags - the whole lot was also covered with a frost blanket.

For dry plants, this worked well enough and one actually showed quite a bit of growth from first harvest:

Checking on them today, some of the wetter harvested plant stems were getting a bit mushy, so I decided to pull and compare.

The whole harvest.

As the commercial variety Sunset survived the critter attack, I'm using it as a convenient control. It is a fast-to-bulk variety.

Seedling yields were variable of course. Growing out from seed allows for selection from novel varieties. I choose the right hand side:

 photo IMG_2179.jpg
The yield from two seedlings that had grown side by side.

Best yield was this pink and white one at 85 grams. P.S. This is a crappy yield but I was encouraged:

Dreaming of this weigh scale being filled one day.

Here are some larger tubers with Canadian change for scale. Sunset (standard variety) on bottom:

 photo IMG_2197.jpg
One of the fun things about oca is the variation in tuber colour.

Next year, I have some ideas to grow better, bigger plants with hopefully bigger, better yields. As it is, I found oca fun to grow. Selection from tubers is appealing as if you get something interesting, it is easy to clonally propagate.

P.S. I've heard of several successful non BC Canadian oca growers. Two live in close-to-maritime conditions favouring oca growth and one just developed this mania this year, growing them in Manitoba! With help from his heated oca-hut, he had quite a respectable harvest. There are also a handful (that I know of) of other crazy folk, like me, in less favourable locations in Ontario or should I say partners in plant exploration.

Other ocaphiles:

Radix rhizowen
Wetting the Beds

* New Zealand and South America are known to grow a few too.

How to grow great cabbage

The very slow, roundabout story of how to grow great cabbage.

Total time for project: approx. 15 years in 16 easy steps.

 photo IMG_1624.jpg
A row of lovely blush cross cabbage after frost.

Step 1: Decide that you like cooking and that growing herbs is cheaper than buying them. 
Time - Several trips to the grocery store
Time - 5 min.
Step 3: Scroll/flip through seed catalogues with an almost guilty relish, picking reliable staples like 
Red Rock Mammoth cabbage and interesting plants like San Michele blush savoy. 
Time - Endlessly blissful hours
Step 4: Have mixed success but vow that next year will be better.
 Time - However long is required to realize that gardening is easy and hard, simple and complicated, beautiful and defeating; That it is worth every minute.

 photo IMG_1705.jpg
It's bigger than her head! It's so big that it was blowing up!

Step 5: Finally crack this cabbage growing thing, at least most of the time.
Time: one wonderful season + many great meals
Step 6: Start hanging out with seed savers and amateur plant breeders. 
Time: Varies, may not happen. I recommend it though.
Time: Several snow blind months
Step 8: Remember hearing something about cabbages being outbreeders and mostly self infertile. Have a sudden idea
Time: A flash!

 photo IMG_1718.jpg
Red rock mammoth quartered.

Step 9: Almost lose precious San Michele pods because someone ripped off a seeding stem. For no Reason! Consider stationing guards around the remainder. Get seeds by careful winnowing and threshing. 
Time: One feverish summer of plant joy.
Step 10: Share seeds, grow out cabbage again and again. Get wonderful reviews because this is one excellent cabbage
Time: Several years.
Step 11: Attempt to overwinter f1s. Fail. 
Time: Several snow blind months + the mud season x 2
Step 12: Take cabbage cuttings and discover they root really easily. Overwinter inside. Be surprised when they flower without vernalization. Baby. Hand pollinate. Save seeds.**
Time: More than half a year plus many delicate minutes with anthers and stigmas.

 photo IMG_8768.jpg
This is kale, but I've had cabbage survive and resprout. Not only that but I've found that if I bring in the freshly dug roots of cabbage in the spring, they will sprout along the root rather like seakale thongs. 

Step 13: Grow the last of the RRMxSMf1s 
Time: Feb-April plant out
Step 14: Let the sun shine, the rain pour and the frost come. Harvest those that are starting to become slimy, split from the rain or just look a bit sad from the constant attack of earwigs, caterpillars, slugs, pill bugs and more. 
Time: May to Sept
Step 15: Eat 
Time: Whenever possible in a multitude of ways
Step 16: Stare at the little jar of f2s seeds with excitement. 
Time: Ongoing.

* I wasn't writing a garden blog back then. In fact, I only started writing a garden blog several years later after my husband (aka non-gardening partner) diplomatically suggested that perhaps I'd like to share my enthusiasm for growing things with OTHER PEOPLE (rather than with him). This post was from my original blog several years after the affliction became acute.

** I don't have a post on this because I abandoned this blog for my gardening friends on Facebook, started a new business, family and other excuses. I did share photos on some edible plant geek sites like Homegrown Goodness (an amazing resource) it seems.

I had a wonderful morning watching the frost add its glistening touch to the garden. Before the tender plants blackened and wilted, they were caught frozen but perfect. As the sun swept across the gardens, there was a sound like the faintest bells and the drip, drip as the ice melted.

Though most of at the frost tender crop had been harvested, I covered some rare root crops that I am trying. The ground was still moist and warm so they were fine. I was intrigued by the dahlias however as frost seem to dance among them: hitting some but not others.

Stephen Barstow coming to Ottawa

I'm very excited (so much so that I actually wrote a blog post) that my dear friend Stephen Barstow is coming to Ottawa for a visit. I've been corresponding and seed trading with him for many, many years. It is a delight to finally meet him in person. Even better is that he is offering to give a talk on his upcoming book Around the World in 80 Plants on Edimentals (edible ornamentals). When I was just a little seedling asking questions or sharing my wide eyed plant joy, Stephen (also known as Stevil on the forums) would be sure to answer with his own joy and generous advice. If ever there was someone who I wanted to write a plant book, it was he.

Email me if you'd like to find out more about the details of this talk:

Around the world in 80 permaveggies!

Workshop with Stephen Barstow, the man who cultivates 2,000 vegetables in his own garden outside Trondheim in Norway.

This workshop will be in the form of a powerpoint talk about 80 of Stephen’s favourite perennial vegetables, including several historic Norwegian vegetables. A number of familiar ornamental perennials that can be used in cooking (edimentals), for example Hosta and daylily. Stephen takes us on a trip around the world from Norway, through Europe and the Mediterranean countries, through Asia, the Himalayas, Siberia, East Asia, South and North America. Many of the plants were and still are local wild foraged vegetables that became domesticated locally. We will hear the stories behind the plants and how they were used in their country of origin as well as experience from growing them in Norway ....many are ideal for the forest garden. There will be plenty of time to ask questions as we follow the plants around the world.

The journey around the world will take roughly 3-4 hours....

Stephen main job is with the sea (ocean wave climatologist) but has in recent years also worked on projects for the Norwegian Genetic Resource Centre, mainly collecting old Norwegian perennial vegetables and herbs! Stephen has led the Norwegian Seed Savers since its start in 2006.

Forest Garden Update

This year, I can see, that the forest garden is turning a corner. We inherited a homestead orchard containing apples, pears, serviceberry, chokecherry, currants, grapes and plums. It had been tilled and planted up with squash. There was also a tilled veggie patch beside. I have been converting the orchard into a forest garden and the veggie patch into a sunny demonstration garden.

 photo IMG_9021.jpg
Grape planted with golden garlic (Allium moly), and oregano. Some bread seed poppy (Papaver somniferum) is also making itself at home in the area. 

September 2010, I fall seeded a bunch a lot of plants including good king henry (Chenopodium bonus-henricus), nepeta, kale, perennial sunflowers (Helianthus maximiliani), bloody dock (rumen sanguineus), alliums, mustards, chicory, parsnips, lupins and much, much more.

 photo IMG_9027.jpg
Yellow: Zizia aurea and golden alyssum (Aurinia saxatilis) in the distance and goji berry.

Season 2011: Wonderful growing season though I did have quite a few brassica flea beetles mid-summer. Little would I know that was my initiation into what was to be the zoo of flea beetles. Garden was expanded. Paths and beds put in.

 photo IMG_9018.jpg
Perennial leek 'Oeprei' with little violets (Viola cornuta) as part of the sunny demo bed.

Season 2012: Season started early followed by late frost, once in 100 year drought and hungry pests. Then we added another baby to the family and it finally rained. Garden was messy at best though I did get some produce.

 photo IMG_9010.jpg
Viola odorata 'bicolor' with English daisy (Bellis perennis) and rhubarb.

Season 2013: Still ansy from 2012 and with a new baby in tow, I try covering the ground with limited success.

 photo IMG_9029.jpg
A hairless version of Sweet Cicely (Myhrris odorata) beneath an apple tree. On the other side is my tallest Hablitzia and wild ginger (Asarum canadense) too.

Season 2014: Perennials like Blue chives (Allium nutans), buckler leaf sorrel (Rumex scutatus), hablitzia, walking onion, rhubarb, strawberry spinach (Chenopodium capitatum), patience dock and more are really starting to shine. The ground is growing more edibles, beneficials and beauty than it is weeds (which have their edible, beneficial and beautiful side of course). I feel we have turned a corner.

 photo IMG_9028.jpg
I rather like how Seakale 'Lilywhite' (Crambe maritima) and Blue Alkanet look together. I imagine they'll be even more spectacular in bloom.

I was happy to see good survival of soldier mallow, poppy mallow, monkey flower, and overwintering of roots like turnip, fennel and parsley for seed. Lots of new plants to the garden too like udo (Aralia cordata), Beetroot bellflower (Campanula punctata) and variegated daylily (Hemerocallis sp.). Any plants that don't go in nursery sales this year, will be planted either in propagation beds or in the forest garden proper. The forest is really filling in now!

Dear followers,

I feel like one of those bloggers that's falling into the trap of constantly apologizing for why they haven't written in a while. I wish instead that I could put together pretty pictures into the posts I plan in my head while getting plants ready to go to market, edging and weeding the garden, harvesting and making stuff and taking care of the food. Sleep? Don't be silly. No time for that.

Anyhow, if you would like to talk gardening with me, join me on at one of the dates below. Theoretically I'll be less busy in July…

Ottawa Gardener

In other news:

May 24: I bring a tray of purple plants (perilla, orach, basil, kale and amaranth) to the market along with other stuff (perennial leek, sweet cicely, lovage, salad burnet, poppy mallow, red bunching onion, anise hyssop, mint, oregano etc..)
May 25: Kids in the Pumpkin Patch Begins!
May 25: Join the COG-OSO demo garden team

Sugar's end, Spring's beginning

I've decided that the end of sugaring - maple syrup making - is the official start of spring. The sap has run up to the branches and plans on staying there causing the flowers to bloom and the leaves to unfurl. With so many posts on making maple syrup featuring knee deep snow and taps intact, I thought it would be fun to show you what our forest looks like at the end of the season.

 photo IMG_8509.jpg
Small wasps sipping from the tap.

Warm weather wakes up the insects which head to the taps to refuel. It's a fascinating way to do a bug survey. This is the big reason I removed the taps in some trees that were still not 'green' because they were swimming with bugs! Don't worry, I rescued them.

 photo IMG_8500.jpg
Literally swimming in bees and wasps: all set free.

A closeup of a couple native bees:

 photo IMG_8502.jpg
Small native bees: two types. Let's see (PS though I like bugs, I haven't had much opportunity to learn their names. There was also a plethora of flies: some shiny blue, some striped, some dull black etc...) um, I'm going with sweat bee and the cutest bee ever (no, not an official name). All educated guesses welcome.

Look at this cool one! Believe it or not, I actually loved bugs before I loved plants. In fact, I liked rocks before I liked bugs. Thankfully all these interests are intertwined and growing plants as a hobby is a much better conversation starter than check out the folding in this gneiss or wow a cow patty fly.

Ophion wasp which are short tailed Ichneumon wasps is my guess

The variously named beer or picnic beetle. I guess it depends on what your outdoor tipple looks like:

The first bugs to the buckets are the owl-faced moths (P.S. This common name which captures their faces well, does not appear to correspond with pictures I found on google so it might be a local name). This one is passed on but you can see why people round here call it owl-faced.

Um, Andrena (yellow-orange haired one) and some sort of little parasitoid wasp?

There were also mourning cloaks and comma-type butterflies along with assorted flies, fireflies, green stinkbug, a two spotted black and yellow ladybug, and tiny tawny metallic beetles along with moths.

Now we clean the buckets and spiles and put them away until next year's thaw. In the meantime, hard work and mother nature have filled our larder with many jars of delicious maple syrup!

It really appears like the kids were helping in this photo doesn't it? Don't believe everything you see… They did have fun however.

Last Frost: An exposé

 photo IMG_8004.jpg
2012 tomato seedlings hanging out in a small greenhouse. That was a warm year.

Now that you are diligently starting seeds, you may have googled last frost date and found that it is in the first week of May! Before you start counting back six weeks, remember this is the AVERAGE last frost date. This means that when all the last frost dates for last fifty years including those that occurred in April and those that occurred in June were averaged out, it gave May 6th as the middle point. This does not mean that we can rely on it as the day after which we can plant out tomatoes. To do that, we have to do a little speculating.

At the beginning of May, the risk for frost is still relatively high but as May fades into June, it drops off quickly to very little chance. Therefore every week waited, is less risky. This might be balanced off of other needs such as growing season, absences from the garden, ability to protect plants under plastic or a winter blanket or a particular microclimate.

Last frost is not 0C

But wait, water freezes at 0C like we were taught at school right? Well, yes, the freezing point of water is 0C however there are a couple complicating factors. Firstly, water is actually at its most dense at 4C. The molecules are then closest together and cannot easily move past each other. They start to arrange themselves into what will be their solid crystalline structure: ice. Unlike most solids, water expands as it freezes. One of the interesting consequences of this is that ice forms and floats on the surface of a pond. Imagine if it didn't!

Secondly, just because the thermometer said 4C on your house, does not mean that little hollow in the yard was not at or below 0C since cold air sinks. Air circulation, humidity and cloud cover all play a part. For example, wind can keep air moving around and prevent it from settling and open skies mean that ground heat may be lost. Also some materials, like metal, cool more quickly meaning you might have frost on your car but not on the ground.

I plant before last frost

 photo IMG_7910.jpg
Bellis perennis - English Daisy - growing under lights for spring flowers and greens.

But not tomatoes. I plant all sorts of greens, roots and peas even though there is the possibility of last frost. Plants' frost tolerance vary (sometimes even within a particular plant's life cycle) so that though peas can be planted even though there may be dusting of snow in the future - assuming the soil is workable - beans will rot in the ground or die if they sprout. Peas and parsnips are amoung the most frost hardy seedlings I know. Others will take a little cold such as lettuce and carrots though not a heavy frost. And still others are fair weather plants and must only be planted out after chance of frost such as tomatoes and cucumbers.

What this means is that when a seed package says start 4-6 weeks before planting out, they may not be referring to after last frost. Violas, for example, can be planted out when the temperature are still cool. As they need quite a big headstart, you'll be starting those in early winter and planting out in mid-spring!

Knowing what to plant when will keep it from being a one-stop weekend of planting fury in late May as well as extending your season. Another planting of frost hardy greens, for example, can be sowed to mature after first frost in autumn.

Of course, there is frost and there is frost. A light frost above -2C is different from a heavy frost below -4 where the ground freezes and different again if it is a one night thing or continuing for weeks. 

Frost as a helper

 photo 1531554_667734593291229_2117727198_n-1.jpg
'Grow-boxes' are my little mini-greenhouses with frost hardy seedlings.

Many seeds have built in dormancy mechanisms that keep them from germinating until conditions are right for maximum success. This is quite common with wildflowers and trees that have evolved in temperate areas such as around Ottawa. Needing a period of cold before popping roots means they'll germinate in the spring. Some even require oscillating temperatures. If you have some wildflower seeds that you haven't stratified (in the fridge or seeded in the garden in the fall or by wintersowing), then you can try putting them out very early in the spring. The soil will be moist and cold temperatures are probably still in the forecast. You may also have time to moist stratify in the fridge using the baggie method.

Sometimes, plants are started very, very early in order to get them out when it is cold so that you trick them into thinking they have already gone through one complete growing season including winter. This is done to get certain plants to flower the first year when they would normally wait until the second such as globe artichoke or sweet william.

Even a few frost tender plants can be planted out a few weeks early (if you want to risk it), including potatoes. As these are under heavy piles of insulating mulch/dirt, their foliage usually takes a while before it is exposed to the air above so you can put out a few weeks before you are absolutely sure there will be no more frost. 

Thwarting last frost: plasticulture

 photo 1004850_667734439957911_1463239326_n-1.jpg
Inside the grow-boxes above are some seeds and seedlings. Here are some crowded swiss chard in need of a little thinning. Look at the temperature inside. Outside it was about -2C but sunny.

Some people plan on putting out their vegetables under season extension devices such as walls-o-water, cold frames, polytunnels, cloches or beneath floating row covers. These can all help moderate the temperature though they are not fail-safe. I like to use these for plants that are frost tolerant. They won't be killed if temperatures do drop but they may grow faster and experience less stress with their blankies overtop.

If you did plant your tomatoes and think that a frost blanket will not be enough AND you don't have a pile of plants, you can dig them up and replant again later. It's not the best solution but it will save your plants.

When is last frost REALLY?

 photo IMG_8051.jpg
Litchi tomato or vila-vila, a nightshade with yummy fruit and ouchy spines. It will withstand light frosts when mature (not tried with seedlings)

It varies from year to year. That is the joy of gardening. We are working with nature who is not always so predictable. Generally it is safe to put out tender starts somewhere around the end of May though occasionally I've had to wait until the first week of June. So when calculating when to start seeds, count six weeks back from mid-late May rather than early May. However, if you've given your tomatoes a couple extra weeks head start, it's not a problem. As long as they are in big enough pots, they can wait until the weather warms. If you have really big tomato babies, plant a portion of the stem under ground as they will root along the stem. This is a trick for a sturdy plant. 

I wait to plant out tomatoes around the third week of May and then look at the longterm forecast. The risk of frost drops precipitously as we approach June. If it looks fair, then I'll plant but with the proviso that I might have to cover if the weather takes a sudden turn. Also weather trends can help you determine if it will be a late or early year. Looking at the long-longterm forecast for spring 2014 suggests lower than average temperatures. Stormy, cold weather has been the norm since last fall and it doesn't seem to be letting up. I would probably not even contemplate planting out until near the end of May unless we get a sudden reversal of fortune. 

What kind of planter are you?

1. May is spring:
* Lives in a sheltered place
* Has lots of seeds or plants of frost tender varieties
* Doesn't really care if everything needs replanting
* Gardens in pots that can be moved inside
Will plant at the beginning of May.
Risk Taker

2. Middle May:
* Plants when it's getting warm 
* Lives in the city or a sheltered location, not a frost pocket
* Has to go away on a trip at the end of May (my usual reason)
* Will happily cover if there is frost
Plants when the weather is fine

3. Late May:
* May 2-4 weekend is when you plant tomatoes!
* I have to plant. My seedlings are crawling out of their pots!
It's worked for generations!

4. Beginning of June:
* There is always a late frost (not so)
* These are my precious babies and I'm not risking them.
* Too much work to cover
* I just bought these seedlings. That's okay right?
Plants when danger of frost is a distant memory
Nervous Nelly or Nettle if you prefer

Mid June:
* Oops, I have to plant a garden?

Right, okay, so just tell me when to plant them!

As I said, gardening, like nature, is a wonder of patterns and variation. If I were to advise someone, I'd say around the long May weekend but that every year is different. Many, many times I've planted out in mid-May with excellent results especially in the city. In the country, I try to wait until around the end of the month as I have a lot more plants than I want to bother to cover. I have seen last frost as early as the end of April and as late as the first week of June. If I had to pin a number on it, I'd say around May 20 but if I had to guess for this year, I'm going with May 31st.

Lastly, the proper wording on seed packets for planting out should be 'after all danger of frost' rather than after last frost.

Business Card Saga: Aster Lane Edibles

Why it took me so long to get a business card: a conversation with myself (and a few others).

Me: You need a business card.
Myself: Why?

Me: People expect it.
Myself: But they just bury those things at the bottom of their bags to be thrown out when they get around to cleaning them. They pick them up and say "Who the heck was that and where was I?"

Me: No that's just you.
Myself: I'm pretty sure it's not just me.

… 6 months later…

Me: You should really get around to that card.
Myself: Let's talk honestly here. Cards are boring.

Me: Then make an interesting card.

… months later…

Me: Why not a planting schedule? That would be useful. A little reference pocket thingie.
Myself: On a card? 

Me: Yeah.
Myself: Good luck.

… a month later …

Me: You're right, that was tricky. Now to the printer. But what if they screw it up?
Myself: Have some faith.

… Months and months later …

Me: Do you think your graphic design husband would help me create an exact document of something? 
Friend: I'm sure he will.

… visit to a common copy place that shall remain nameless …

Them: What? Folded? Like a gift card? But you want a business card right? I think we're going to have to send this to our specialty print shop. And what are these other lines for on the file? We can only print what we can see.
Me: They are formatting lines. I figured that you could remove them with your fancy programs. Will you have them ready like within a week. I want to have them for an event I'm going to.

Them: -incredulous look-

… several phone calls later, an independent print shop …

Me: I have these files and I need them to transform into a business card through the magic of computers and large printing machines by tomorrow.
Them: Why certainly.

Experiments with hot and cold

I'm in the midst of two experiments dealing with two of my favourite vegetables that like different weather regimes.

Experiment I: Cool Cabbage

 photo IMG_7876.jpg
Flowerbuds on rooted cabbage cutting.

*If you have no idea what I just wrote below then go to the bottom*

The first is my San Michele x Red Rock Mammoth cross. If you haven't heard about me gone about it before, well then, welcome to an odyssey. I haven't managed to yet get f2s so I figured I'd try rooting cuttings and overwintering. All was going well but then I realized that I will have to vernalize in order to get flower. Generally I plant out cabbage early without inducing flowering and those heads that have overwintered, so far, have not produced seeds but more heads (part of why I don't have f2s, along with the bugs and freeze-thaw of spring). So I thought they would need a rather long exposure to cold. I started off with sitting them in my shoe room near a window. It gets cold in there but not horribly. They were there for a week. Then I put them in the garage window where I had planned on leaving them until the end of winter but only managed they were only there for a few days before it dipped into minus double digits so I moved them back inside planning on doing the shoe room treatment again. Mistake. They immediately started elongating and producing flower buds. Dang it!! Now, I have a few that are further behind and some that I did not attempt to vernalize so all hope is not lost. Not only that but in the spring, I will take cuttings from the plants emerging from the snow before they get all freeze-thaw-mushed on me. However, now the experiment has taken a turn. I plan on potting on again and hand pollinating with the hope of getting viable seed. Lesson learned I guess. Hold off on the vernalization until March.

I *could* potentially remove flower heads until spring. Maybe I'll do half and half.

Origins of this Cabbage

Experiment II: Hot (Sweet) Potato

  photo IMG_7879.jpg
These are freshly slipped sweet potato plantlets, doing some branching which I hope to cut off and root.

This is not a very serious experiment, I have to say. I am just starting my shoots really early so that I can cut them into sections producing more plants than usual for spring with fewer tubers. So far, roaring success. Sweets root easily from cuttings. Nothing further to report yet. The danger, I suppose would be if I get an indoor bug infestation. Not to fear, I have more roots that I can force later which is good as I am predicting a late spring (sorry folks). Don't cry though, I'm using my 'intuition' rather than probabilistic forecasting. That and the amount of accumulated snow and cold weather patterns.

 Extra Experiment: Craggy 2 year old, broken sweet potato tubers will sprout. Go figure.

*** For those that didn't know what the heck I was going on about because your plant obsession hasn't quite reached critical levels, here is a translation. P.S. There is plenty of room in the rabbit hole for you.

I let the bees frolic in the flowers of two types of cabbage. One was called San Michele. The other was named Red Rock Mammoth. They made seed babies. As this is the first generation of the cross, they were called f1s. I loved the variety and wanted to see if I could get it to be stable. This is because when I let these babies flower and set seeds, the characteristics will all jumble up again making for lots of variation. I would have to select plants that I liked and save seed for generations until the babies produced were more or less the type I wanted. But to start, I need the second generation or f2s. Cabbage usually flowers in the second year after winter. I have been trying to overwinter my first generation of the cross but had problems. These were 1) eaten by bugs, 2) turned to mush because of oscillating temperatures in spring and 3) didn't both to flower and made another cabbage head instead. Now, I plan on trying a frost blanket, also called a floating row cover this year, (duh) but foliage emerging from snow is very tender so I'm not convinced it will work. Cabbage heads always mush out for me in winter but I do get a lot of leaves growing out of the stems in spring and sometimes flowers which is why I was able to make the cross in the first place.

As an insurance policy, I decided to take advantage of a trick that many members of the cabbage family have which is that they can grow roots from sprouts off the stem. I plucked those and put them in moist soil. Some, I cut a bit of the stem off too with the sprout. They rooted and grew very well but they were inside not exposed to any cold. The aim was to get them to flower not make more cabbage heads. So I tried to give them some gentle cold in order to get them to spring where I could plant them out and they could flower for me. Fail. They flowered early.

This means that to rescue the experiment, I am going to have to move pollen from the male parts of the flowers to another plant's female flowers in hopes of getting some mature seed that will grow. Wish me luck!

Things are sprouting in my fridge...

…on purpose. I'm stratifying which means giving seeds a period of moist cold to overcome germination  inhibition so they will sprout.

I place seeds on paper towels or coffee filters then put in a plastic baggie. This takes up very little space in my fridge or other location that I am giving seeds special treatment. You can also use your baggie to give seeds oscillating temperatures or warm treatment. I use the latter to get peppers to germinate faster.

Baby with breakfast on his face helping.

For very large seed that won't be in good contact with the paper towel, I've heard of people using cotton balls but I use vermiculite. I also use vermiculite with very, very small seed so that I can sprinkle the whole mix in the seeding tray when ready. Sand would probably be a good substitute.

They would stay in the fridge for a certain period of time say six weeks or whatever is recommended (yes sometimes there are no specific recommendations). During this time, you are telling the seed that it is winter and when you take them out of the fridge, they are experiencing spring so it's a good time to sprout. Only, many seeds will not wait their allotted time. Whether this be because those particular seeds or that variety does not really need the cold stratification AND also does not need high temperatures to sprout or because they prefer to germinate in the fridge-like temperatures of early spring, is something to speculate upon. Therefore, I check my baggies frequently.

Wild plums from a local source

Here, some wild plums - perhaps Prunus nigra - started to germinate after six months in the crisper whereas their cousin nanking cherry - Prunus tormentosa - jumped into growth after only a few weeks messing my plan of holding off until spring to plant. Instead I put the sprouting seedlings in the ground in fall.

Hablitzia tamnoides is reputed to prefer cooler temps to germinate though it seems somewhat adaptable. Here is my own seed crop throwing roots.

Hablitzia tamnoides, our seed for Aster Lane Edibles

I'm using the baggie method because I want to grow some of these plants big enough to sell in the spring otherwise I'd probably just wintersow. This is using a recycled (or not) plastic container with drainage and air holes partially filled with soil and seed that acts like a mini greenhouse. It is great for cold hardy greens, plants that volunteer, wild flowers and other plants that need a period of cold to germinate or at least don't mind it.

You can even snow sow. Yes, that's tossing seed on top of snow. This is a version of stratification and seems to me that it would be most effective if done in the fall or early spring just before a snowfall that would insulate the seeds and help work them to the ground.
