PlantFiles: Rape
Brassica napus var. oleifera

Accidently got plants in with collard plants. We could tell in just a few weeks that these were more vigorous, and the leaves had tiny stickers on the backside. Their flavor and leaf texture was different from any other greens we had ever grown.
Flavorwise, I would never intentionally plant them because I didn't care for the flavor.

This is the older generic cultivar of rape, which is used for winter cover crops, and green manure. In my youth we planted it for winter hog pasture. It is edible and similar to a smooth leaf kale in taste and texture, We use to eat it when other greens played out and the kale became infested with plant lice (aphids). This is the cultivar used for rape seed oil. In the 1970's an improved cultivar was developed in Canada called Canola and is used for Canola oil.
