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).

Oca on the move!

My oca (Oxalis tuberosa) plants (grown in large pots) have now been moved inside to be finished off for Xmas. A couple were still in flower!! It should be a good crop!
Oca are difficult to get a good crop off in the north as tuberisation doesn’t start until days are short…and early frost /cool weather can stop development and lead to almost no yield!
