Bush Cabbage

Bountiful Gardens is now out of business, but you can get tree collard cuttings from Quail Seeds in California:   tree collards
This variety is exceptionally tender, especially in winter. It doesn't normally set seed, and has been passed from gardener to gardener for centuries. It was preserved by African-American gardeners and has been mostly unknown elsewhere until recently.

Quail Seeds also has some perennial vegetables that grow from seed, and seeds for non-hybrid, true-breeding comfrey. It is unusual to find the true comfrey species (Symphytum officinalis) that grows from seed---most of what people grow is the Bocking hybid which is sterile.

Loved this post! Thank you for sharing and hello from the UK. I am Portuguese, raised in the USA, and now live in London. I have a very popular website and blog, where I share my Portuguese recipes in English. www.thepurpledoorsupperclub.com.
I just bought some 100 Galega seeds and can't wait to plant them in my garden. Fingers crossed Have a great day.

No apologies for revisiting an old thread.  I've been given a lovely sturdy plant of 'asturian tree cabbage' by a customer.  Any tips on planting it out? Will it need full sun for me since I've got pretty cool summers or is it pretty tolerant?  My Taunton Deane perennial kale really thrives here, so will the tree cabbage like similar conditions?

Update on the tree cabbage I was given. I planted it in a reasonably sunny spot in good soil and it grew OK, but I made the mistake of not picking the flower heads when they formed last year and it did not come back this year. It always looked a bit pale too, as if it wasn't quite happy here. I think I'll stick with my Taunton Dean kale which grows much more convincingly here.

I'm glad your Taunton Deane kale survived the winter, Nancy!

Unfortunately the second cold snap last winter killed my huge, beautiful plant. I should have taken a couple of side shoot cuttings in autumn, as it was it's third winter and I read they're short-lived. How old are your plants?

Oh goodness! I'm not sure. I would say my Taunton Dean is about 6 years old (the Daubenton's I had at the same time never established). I can send you some cuttings if you like (send me a pm) - I'm trying to get some to take myself at the moment, but it's not helped by the dry weather. I rarely have to wish for rain, but this year I'm close to it!
