Hi Paul The Koanga Institute have seeds available they call it the Dalmatian cabbage. I think i have seen it advertised in either the Egmont seeds catalogue or the Kings seeds catalogue. All three have on line catalogues. Collards are a type of Brassica. Regards Barry

I can't find collards anywhere in Melbourne, Victoria. We have three varieties of kale available; the dinasour, curly leaf variety and a small purple kind but no kale and sellers have no idea what I am talking about. I just came from living in Canada and the USA where it's available everywhere. Any help pls?

Collard is commonly known as kale and they come from the brassica family which is cabbage,broccoli,brussel sprouts etc... Most kale is ornamental and not for eating but i have seen the edible type sold in punnets at nurseries but i have to say i have not seen them for a long time.

"Most kale is ornamental and not for eating but i have seen the edible type sold in punnets at nurseries but i have to say i have not seen them for a long time." Is this true? Ornamental? I've got curly leafed Kale and I use it in my green smoothies. Should I be worried?

No, curly kale is a vegetable. I think it would be hard to mistake ornamental kale seedlings for edible kale, not least because they would be found in different sections of the garden centre! There are a number of different kinds of edible kale, more often sold as seed than as seedlings, and not that often seen at mainstream nurseries/seed suppliers.

Ornamental kales are quite safe, but don't taste as nice as the culinary types. Curly leafed kale is a culinary variety and tastes fine. I got seeds from Eden seeds.
