For anyone in Adelaide, I got some collard seeds yesterday from Wilson's organics which is just off gouger st by the central markets. They are from Eden seeds who also have a website with heaps of different seeds. Hope this helps.

Collard Greens is not an expression used in Australia. Thanks Sri for listing what they include: broccoli, brussel sprouts etc

Sorry Karen, whoever told you that collard greens are broccoli and Brussel sprouts or even similar, had no idea what they are talking about. You will actually find that collard greens are similar to kale. A leafy green vegetable grown similar to a lettuce or cabbage.

My collards are starting to grow what looks like seed pods at the top of the plant. How do I harvest the seeds?

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.

I did not start my collard, cabbage, seed in March - can I plant the seeds in the garden now in mid-July? Also, can I plant cauliflower in the garden from seed in July? I live in zone 6b. Thanks!!!
