Heirloom Collard Green Seeds - Packet of 100 seeds
A couple of these hardy plants will produce enough for your guinea pigs as well as the family.
I have three plants and every week I am able to harvest a brown paper bag full of the largest leaves. This is a winter plant they say but here in sunny California mine have been doing great and growing leaves all through the summer. If the plants goes to seed just remove the flowers (and feed to the pigs), so that more leaves will continue to be produced. I chose this one to promote because even I can grow this plant. Does so well and it quite prolific.
Collard describes certain loose-leafed cultivars of Brassica oleracea, the same species as many common vegetables, including cabbage and broccoli. Collard is part of the Acephala Group of the species, which includes kale and spring greens. They are in the same cultivar group owing to their genetic similarity
