I was showing a journalist around the winter edible garden and cellar this morning and dug up some nodding (Chicago) onions (Allium cernuum) and picked a few Hablitzia shoots, so why not turn it into lunch! I sliced an oca (Oxalis tuberosa) in with the vegetables. Scambled Habby Chicago eggs is simple gourmet midwinter food from garden to table in no time!

Cellar and Garden Greens: 6th April 2022
The greens that went into last night’s wholegrain spelt quiche are listed below the picture!
CELLAR: Dystaenia takesimana shoots; Forced hogweed (bjørnekjeks) shoots (Heracleum spp.); Forced Taraxacum (dandelion / løvetann); nederst til høyre: Witloof chicory (sikkori); øverst til høyre: swiss chard (mangold)
GARDEN: Various hybrid onions (Allium senescens x nutans) and Hablitzia tamnoides (Caucasian spinach / stjernemelde)
Dissected dandelion bud
We’ve been eating dandelions for lunch every day now for almost 3 months from the roots dug in the autumn and there’s still loads (see my post in January and February here: https://www.edimentals.com/blog/?p=27183 and https://www.edimentals.com/blog/?p=27343). We basically cut at the base with scissors and yesterday accidentally dissected a flower bud! The dandelions will respond with new leaf and flower shoots.

Forced March Perennial Greens
In order to lengthen the season for harvesting of perennial vegetables, I dig up roots of a selection in the autumn and plant them in garden soil in large buckets (which I have a surplus of through my Allium project, now moved to the botanical gardens). As I explain in the video, all of these can be stored outside exposed to the cold as they are very hardy (minimum about -20C here), but some get a head start by moving into my cold cellar where they start growing slowly in the dark. Welcome to my living room:
These were the forced veggies used one day last week, from top left and across – Heracleum sibiricum (hogweed / bjørnekjeks); Campanula latifolia (giant bellflower / storklokke); Myrrhis odorata (sweet cicely / spansk kjørvel); Taraxacum officinale (dandelion / løvetann); (bottom row): Allium angulosum; Ficaria verna (lesser celandine / vårkål); Allium flavescens and Armoracia rusticana (horseradish / pepperrot); (centre right): wild buckwheat / vill bokhvete shoots – Fagopyrum tataricum)
Still green after the freeze
Since New Year, only one day had been slightly above zero with temperatures regularly below -15C, but then a big shift in the weather happened a few days ago and it’s now 25C warmer than it was a week ago!
It’s interesting to see how hardy some Alliums are, even when not insulated by snow and here are 3 of the most hardy: Allium carinatum (keeled garlic / rosenløk), Allium flavum (small yellow onion / doggløk) and Allium cernuum (nodding onion /prærieløk) can all be harvested even though the soil is frozen solid. Hablitzia tamnoides (Caucasian spinach / stjernemelde) shoots are also developing nicely and I’ll have a few for lunch today along with the onions.
Winter garlic shoots 2020-2021
I started this week sprouting the first garlic bulbils of the winter. Of the garlic varieties I grow, Aleksandra, Estonian Red and Valdres are all very similar (I suspect they may be the same) have the perfect size and number of bulbils for sprouting. I counted 90 bulbils on one typical head this evening. They are planted on ordinary garden soil (picture) and covered with a few cm of sterile soil so that seeds in the soil don’t quickly appear. The pot is put in a kitchen window to sprout and the shoots can be harvested two or three times before they give up.
Some people remove the scapes (flower stems) of hard neck garlic in summer to get a better yield. I have compared the size of garlic on plants with and without removing the scapes and found little or no difference here. I therefore leave the bulbils to develop on most of my plants. For me it maybe adds maybe 50% to the value of the plants, so more than compensates a small yield decrease! The only ones I remove are harvested for the scapes which are delicious in summer stir-fries.
Harvesting winter vegetables before the freeze
I’ve been self-sufficient in fresh vegetables year round and have blogged and lectured about how I can do this even in winter without a greenhouse, without a freezer and without using additional energy apart from my own manual labour :) The most important factor allowing me to do this is the cold cellar under the house where I can store vegetables cold and frost free. None of the common winter leafy green vegetables further south in Europe – kales (grønnkål), chards (mangold) and leek (purre) – can be reliably overwintered outside here, although winters are getting milder. For example, swiss chard is killed by the first hard frosts which due to our northern location last all day (little direct solar warming at this time of year). Usually I’m taken by surprise by hard frosts in early November and there’s a panic digging up vegetables and I often have to use an iron bar to get through the ice layer. Not so this year. Thanks to corona and a very mild first part of November, I’ve had more time for the harvest. Last week I lifted the swedes and turnips and yesterday the parsnips, jerusalem artichokes and carrots. Today, I moved all the swiss chards, celery and chicories (sikkori) to large buckets, planted in soil, ready to move quickly inside later in the week if necessary as colder weather is forecast. In the past I’ve stored these winter vegetables in hand made wooden crates filled with soil. However, after 20 or so winters, they’re no longer usable and I hadn’t got round to making new ones, so I will store in these large plastic buckets, which had been purchased to plant the Allium collection, now with a permanent home at the Ringve botanical garden.
I’ve also been digging up perennial vegetables for winter forcing. This includes various onions – Allium senescens, Allium flavescens, Allium angulosum and Allium cernuum. In addition, I’ve dug a udo (Aralia cordata) root and also a few ostrich ferns (Matteuccia struthiopteris) and Hosta “Frances Williams” (sieboldiana). Finally, I’ve been digging large amounts of my most important winter vegetable, dandelion! (see my 2018 harvest here: https://www.edimentals.com/blog/?p=20124)
19th November: the next morning it snowed (see the video at the bottom)!
Harvested swiss chards including the Lucullus type and perpetual spinach (all Beta vulgaris var cicla):

Self-sufficient in Cress
One of the easiest seed to save is cress /karse (Lepidium sativum). You can grow a lot of seed in a small space, it dries well on the plants and is easy to process, rubbing the seed pods between your fingers in a bowl and then blowing the chaff away outside. I sprout the seed inside during winter and also sow it outside in spring to harvest the young plants for salads and lunch. leaving a few to grow big for seed.
Giant Ulleung Celery
In my world, plants that are both perennial, edible, ornamental and popular with pollinating insects are the most valuable (I term this class of plants edi-ento-mentals) and the Giant Ulleung Celery, Dystaenia takesimana, ticks all 3 boxes! That it can provide winter greens at a time of year when little else is available is its biggest advantage as an edible plant! This plant has been a closely guarded secret amongst a selected few for many years, but is now poised for the big(ger) time! The fact that I’ve written the article below about this plant is thanks to one man, plant breeder Professor Elwyn Meader (1910-1996) who collected seed on its small home island of Ulleung-do in the East Sea between the Korean peninsular and Japan in 1953! Without his generosity and enthusiasm 30 or so years ago to share seeds, we wouldn’t know about one of the potentially most useful permaculture plants! Please download the article below and seek out plants and seed!

Winter Tradescantia shoots
I’d potted up some Tradescantia ohiensis shoots in the autumn as I’d planned to offer a few roots to members of the Norwegian Seed Savers’ (KVANN) perennial vegetable guild though our autumn catalogue. Well, I lost them….and relocated them this evening as the shoots had grown quite long in the dark cellar, so I cut them to eat this evening:
They have a pleasant mild taste.
