Purple Tree Collards are still our favorite because they rarely bloom and stay more productive year round. They are also aesthetically striking in the landscape because they contrast highly with the other plants due to their coloration.
If you want to harvest and eat the flowers as you would broccoli, you can do so, but the plants will make flowers again and you will be in effect extending the reproductive cycle and delaying the plants’ return to leaf production.
If you don’t eat the flowers, let them bloom and form seed pods. When the pods are turning less green and more brown, you can cut the branches of seeds off. This will be approximately 3-4 months of wait time. Once you cut them off, they should return to vigorous leaf production.
As for domestic animals, horses, goats, pigs, sheep, poultry, and rabbits love them.
