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.

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?
