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.

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?

i see the seed packets everywhere in garden centres at kmart, big w, bunnings etc they are quite in fashion to grow at the moment along with purple carrots!

I would like to grow collards or collard greens. Where can I find seed or seedlings please. Are they the same as silverbeet or does silverbeet have the same or similar levels of Vitamin A?

Hey there, you can buy the seeds online.

But whereabouts online? I have yet to find it available online in NZ and importing it from overseas is likely to run foul of our immigration laws.

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 think they are bolting (going to seed). All the energy is going into stalk and producing seeds. I think they are done when this happens.
