Snow onions


Various Allium species are the hardiest of edible plants either staying green all winter (e.g., Allium cernuum and Allium carinatum) or sprouting very early and able to withstand some frost. With a minimum forecast of -6C tomorrow after a very mild March, it will be interesting to see whether any of these early shooters are damaged. Here are a selection of pictures of Alliums and other early spring shoots in this weeks snow.

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.

Keeled garlic, a useful winter Allium and edimental in summer

There are Allium species that can be harvested year round in the garden, notably nodding onion / Norw:prærieløk (Allium cernuum) which I’ve blogged about before. In autumn, new shoots of Allium carinatum subsp. pulchellum (keeled garlic / Norw: rosenløk) appear and with the mild weather we’ve been experiencing they’ve already reached about 20 cm high. They are hardy and can survive to at least -20C. It’s now in the autumn that this edimental Allium is most useful. I use the shoots in a similar way to chives (Allium schoenoprasum), which died back some time ago and won’t reappear until spring (unless I force them indoors), in salads, cut and sprinkled on sandwiches, in scrambled egg, quiches etc. I use them from October to April.

8. mars: Pizza greens, all harvested outside after most of the snow disappeared during the day. From the top and clockwise; Ficaria verna (lesser celandine / vårkål), Allium cernuum (nodding onion / prærieløk), Hablitzia tamnoides (Caucasian spinach / stjernemelde), Allium carinatum, Allium senescens (or hybrid), Primula veris (cowslip / marianøkleblom), Alliaria petiolata (garlic mustard / løkurt) and Taraxacum spp. (dandelion / løvetann)

There are two colour forms, pink and white which are particularly valuable as they last such a long time and are popular with pollinators:

There are also forms with bulbils which can be a bit invasive:

You’ll see the flowers used as a tasty decoration in my multi-species salads (bottom right in the picture):

Allium carinatum is also popular with pollinators:

Onions in the snow

Several Alliums are extremely hardy and can stand green all winter even when exposed to temperatures under -20C. Similarly, young leaves of species that start to sprout in early spring as soon as the frost disappears near the surface have no problem with snow and frosts. Here are a few after yesterday’s snowfall!

Snow harvest

It snowed all day yesterday, but it’s unfrozen underneath and spring bulbs like snowdrops (snøklokke), coltsfoot (hestehov), winter aconite (vinterblom), Crocus tommasianus and Hepatica transylvanica are in flower under the snow. Remembering where the edibles are located, I can still harvest food under the snow:

Hablitzia tamnoides, Allium carinatum, Ranunculus ficaria var chrysocephalus (lesser celandine / vårkål), Alliaria petiolata (hedge garlic / løkurt) and (forced inside) dandelions (løvetann) 

Sulfur containing winter greens

The most hardy winter greens in my garden are mostly rich in sulfur compounds including various onions (Allium) and onion-tasting brassica, Garlic mustard (løkurt), Alliaria petiolata or is it just coincidence that Alliums and Alliaria are both very hardy. 
Does the sulfur play a role in giving these plants hardiness? The only other plant that I can harvest a little of in midwinter is Hablitzia tamnoides (although it turns red in the coldest weather).

Allium cernuum also stays green through the winter and can be harvested even in the coldest weather!

Garlic mustard (løkurt), Alliaria petiolata is a short-lived annual / biannual that germinates in the autumn here and the leaves often make it through the winter and can be eaten in midwinter!
