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)
Somebody asked me the other day if I use floating mulch (fiberduk / agryl) to be able to harvest all these greens so early. No, no and again no….this is one of the biggest benefits of perennial vegetables….it is totally natural, no microplastics are released into the environment, no oil is needed to plough the fields, significantly less migrant labour is needed and little or no fertiliser and water is needed, it is almost totally free once established and can yield year after year! So, whilst large areas of farmland in the northern hemisphere are being covered by plastic mulches to bring on annual crops for the market earlier, I’d just like to point out that there’s an alternative better way! So, here are the plants that I harvested for yesterday’s delicious green pasta sauce: Armoracia rusticana shoots (horseradish / pepperrot) Myrrhis odorata (sweet cicely / spansk kjørvel) Houttuynia cordata “Chinese Market” (shoots and rhizomes from the cellar; this cultivar is significantly larger than other Houttuynia I’ve grown) (Fish herb, Himalayan water creeper) Allium senescens x nutans (hybrid Siberian onions) Laurus nobilis (bay / laurbær) Brassica oleracea (perennial kales) Crambe maritima (sea kale / strandkål) Taraxacum officinale (dandelion / løvetann) Allium x proliferum (walking onion / luftløk) Hablitzia tamnoides (Caucasian spinach / stjernemelde) Dystaenia takesimana (giant Ulleung celery, seombadi) Oenanthe javanica (seri) Polymnia edulis (yacon) (second picture) plus garlic and chili
Greens (and reds) harvested from under the snow in the garden and in the cellar; Houttuynia cordata are the red shoots bottom leftYacon
“Pepperrot” is the Norwegian name, also known as common man’s wasabi, it’s horseradish, Armoracia rusticana, a multipurpose, perennial, high yield, very hardy vegetable used not only for the roots but also the spring shoots and delicious edible flowers….Here’s a few pictures of today’s cold harvest!
The horseradish bed!
I used a broom to remove the snow…
Large roots
I use the old large roots for forcing spring greens indoors in February / March both green (strong) and blanched for a milder taste
Packed in with damp leaves, they will be moved into the cellar when it gets cold…
