Can one use silverbeet instead of collard greens? Or maybe spinach? Would it be too much different?

Where can I purchase seeds or seedlings of Galician Kale (Couve-galega)? It grows up to about 1 to 1.5 metres on a fairly long single stem and leaves are harvested from near the top as needed. It is common to Portugal and forms the basis of a delicious Portuguese soup called Caldo Verde.

Hi Folks, I trying to locate a supplier of Collard Greens seeds or seedlings in the Perth Western Australia area. I've scoured the usual web sites, without success. I've tried contacting Brisbane Organic Growers of Windsor QLD but it appears their web site is shut down. Can anyone please help me?

Hi David, I'm from Arkansas... I live in Brisbane though... I haven't found anything even close... They throw away the tops of Turnips here too... Maybe try an international seed supplier?

Giot collards from Eden seed and eBay...I let them go to seed in the garden and they self sow well. Not prolific and the white cabbage butterfly have a good go at them more than anything else in the garden. Also grow Kale very well..what an under estimated beauty

Post a question, comment or tip about Collards

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.
