  • Space plants: 16 - 20 inches apart
  • Harvest in 8-11 weeks.
  • Compatible with (can grow beside): Dwarf (bush) beans, beets, celery, cucumber, onions, marigold, nasturtium, rhubarb, aromatic herbs (sage, dill, chamomile)

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.

Culinary hints - cooking and eating Collards

Slice and steam or use in stir-fry

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!!!

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.
