Seed saving talk weekend

Thanks to KVANN (Norwegian Seed Savers) colleague Andrew McMillion for coming up to Trondheim to give his seed saving course for local KVANN and Væres Venner Community Garden members! 


…and there was time for a Malvik visit, a seed saving and breeding chat, a tour of my seed boxes and a little salad with Witloof chicory and dandelion pizza.

Salad ingredients: Celery, three chicory varieties, dandelion (including one flower), carrot, Japanese yams, Allium cernuum and Hablitzia (from the garden), Hristo’s onion (Allium flavescens x nutans?), oca (2 varieties), apple (Aroma), horseradish shoots,  garlic, chives, wild buckwheat shoots and turnip “Målselvnepe”

Chicory / dandelion pizza with 100% coarse wholegrain Svedjerug (rye) sourdough base!

Wild Enoki, Oca and Hablitzia scrambled eggs

Wild Enoki, Oca, Hablitzia, wild buckwheat sprouts, Allium nutans  with dandelion, garlic chilis mixed with scrambled eggs for a delicious home grown and foraged lunch!
Enoki is one of the hardiest fungi appearing often midwinter in mild winters. Also known as velvet shank (vintersopp in Norwegian, meaning winter fungus; Flammulina velutipes). Many had been reporting finding this species recently, and I too found some when I visited the botanical garden the other day! It’s difficult to believe that this is the same fungi as Enokitake or Enoki, sometimes offered in supermarkets and one of the most popular cultivated fungi in the Far East. The cultivated fungi are long and white as they are grown in the dark in an enriched CO2 environment which gives longer stalks.

Rhizo-bacalhau

We occasionally eat wild fish and bacalhau is a favourite made from Norwegian dried cod that can be found in supermarkets here. More or less anything goes in bacalhau (bacalao) and although most people make it in the same way – layers of potato, fish, tomato and onions, often with chili – the Portuguese have hundreds of ways of preparing baccalao (dried cod). Being self-sufficient, detailed recipes aren¨’t useful and we use whatever is available at the moment. Winter is the time for stored bulbs, corms, tubers, rhizomes, and taproots. See below the picture for yesterday’s baccalao ingredients with 14 home grown below surface storage organs plus some greens (I’m pretty sure nobody else had this version of the dish…ever!):

Oca (Oxalis tuberosa): yellow and red varieties
Garlic / hvitløk (Allium sativum)
Wapato (Sagittaria latifolia)
Potato / potet (Solanum tuberosum) – 2 varieties
Jerusalem artichokes / jordskokk (Helianthus tuberosus)
Parsnip / pastinakk (Pastinaca sativa)
Scorzonera / scorsonerrot (Scorzonera hispanica)
Common onion / kepaløk (Allium cepa)
Cacomitl (Tigridia pavonia)
Yacon (Polymnia sonchifolia)
Burdock / storborre (Arctium lappa)
Madeira vine (Anredera cordifolia)
Parsnip / pastinakk (Pastinaca sativa) shoots – had started shooting in the cellar
Leaf beets / bladbete (Beta vulgaris var. flavescens)  – 3 varieties
Allium nutans (forced in the living room)
plus (not home grown) organic tomatoes, olive oil and olives
(I forgot the dandelion…will add tonight: we make enough that it lasts for several days….and the taste improves!)




Habby Chicago Eggs

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!

Oca harvest 2022

Xmas isn’t Xmas without Oca and a hoard of other tubers, served with the traditional nut roast. Pre-xmas preparations includes the annual oca harvest. Oca (Oxalis tuberosa) is a short day root crop hailing from the central and southern Andes. When harvested at the first frosts, yields are poor, the plants needing a long mild autumn to fatten up the tubers for the festive season. I therefore grow my oca in large buckets which we bring into the extension to the house at the first hard frosts which was late October this year. We don’t heat the extension which is normally a fairly constant 5-10C in winter and hence a good place to store vegetables and other plants like my bay tree (Laurus nobilis). There’s no sunlight and I don’t use artificial light so there’s no diurnal variation in temperature either. The oca plants don’t grow vegetatively, but miraculously the tubers do grow over the few weeks to harvest:

 

Xmas day Rhizofantastigora dinner 2021

Xmas dinner in Malvik has been nut roast and roasted roots every year since 1984! This year there were 27 different roots: parsnip, 15 different varieties of potato, bulb onions, Tigridia (cacomitl), wapato (Sagittaria), carrot, beetroot, oca (red and yellow), Madeira vine (Anredera cordifolia), yacon (Polymnia), garlic (Allium sativum), Dioscorea polystachya (Chinese yam) and chicory root (at the top).
The nut roast was made from ground walnuts, hazelnuts and almonds with grated carrots, onion and beetroot with garlic, golpar (Heracleum seed spice), egg, salt, pepper and chili, bedecked with buckwheat groats (home grown by a friend in Czechoslovakia), Himalayan balsam seed,  caraway, dill and alpine bistort bulbils (Polygonum viviparum).


A real Oca yield outside at 63.4N

Two days ago, the latest first frost date was registered in Trondheim for 130 years! This has allowed my oca (Oxalis tuberosa), one of the Lost Crops of the Incas, to develop properly for the first time! This is a short day plant, tuberising late in the season! These were grown in the World Garden at the community garden Væres Venner, one of the gardens in @kvann_norwegianseedsavers Schubelers Network.
An apparent new variety has also turned up and as far as I know no seed has been involved, so I guess it’s a genetic mutation, seemingly halfway between the other two varieties. Of course, I will be replanting this one next year (see the third picture)!
My other pot-grown ocas were moved into my porch extension just before the frost and will be grown on for Xmas harvest as usual.

Tubers and roots; December 2020

A gallery of pictures of tubers and roots which were harvested in December when I had a blog-free month!

Last harvest of 2017 and the most colourful!

I harvested Ulluco and Oca tubers which I grow on indoors from the first frost to the end of the year!This is probably the last time I grow Ulluco for a while due to the UK advice to destroy all Ulluco currently being grown due to the danger of non-native viruses hopping over to other more important crops!

Happy New Edimental Year

Wishing all my friends, family and all the amazing folk I’ve met live and online this year a very happy green year in which things WILL begin to change for the better for our wonderful planet earth!
However, things are not changing for the better for ulluco (Ullucus tuberosus) in the bottom row in this animation as this is the last year I’m growing this wonderfully colourful root crop which I’ve been growing now since 2007 (see the comments below for the reason for this!)
The top two rows are oca (Oxalis tuberosus). Both are from the Andes and were harvested yesterday indoors (grown in large pots brought inside before the first frostsin October).
