Leafy, green vegetable - heat tolerant so a good substitute for kale and cabbage in tropical areas. Also recommended for health reasons.

For best flavor and texture, leaves should be picked before they reach their maximum size.

They are also known as collards in Australia, but they're not very widely available. I ordered seeds from The Lost Seed. Unfortunately I'm unable to post the link but if you google it you should be able to find them.
