I like the idea of a 'new' or ' unusual vegetables' thread,
so I'll put my two bobs worth in and bump it back up again.
Re. Asparagus transplanted from the wild... Yes it transplants easily when plant is dormant.
Dig and replant the crowns in soil prepared in the normal way for asparagus ... It will live for many years.
When I dug mine I chose male plants (no red berries) for two reasons.
I'd rather not have them growing new plants in my garden
and I've heard that male plants are more productive because the don't divert energy to seed production.
I don't know if it's just a myth or not , but the first reason is good enough for me.
I like to pick and eat weeds from my garden
Tonight we had bladder campion (Silene vulgaris) spring shoot along with
unopened salsify (Tragopogon porriferus) flower buds lightly boiled or even just blanched
and then dressed with oil and lemon juice.
We often eat it when it's up and growing .
Also , purselane (Portulaca oleracea) in the summer,
as well as wild rocket (Diplotaxis tenuifolia)
They're all naturalised in my orchard and around the vege patch.
Others , nettles , perennial and annual (Urticaria dioecia and U.minuta)
as well as Alexanders (Smyrnium olusatrum) are also eaten.
Fat hen (Chenopodium album) , huazontle (Chenopodium sp.) and
quelite , another Chenopodium sp. from Mexico)are good cooked they volunteer in my garden.
Tomatillos (Physalis ixocarpa) come up every year in my orchard and are great for salsa.
Carrots, parsnips, chicory and lettuce, though not really new or unusual, also self seed here.
Epazote (Chenopodium ambrosioides) pops up around the garden and
I use it as a flavouring herb for Mexican food.
It's all food I don't have to purposefully cultivate.
