Brassica rapa, a dicot, is an annual herb that is not native to California but was introduced from elsewhere and naturalized in the wild. It is a plant widely cultivated as a leaf vegetable, a root vegetable, and an oilseed. Its roots can be eaten raw or cooked as a vegetable, and the tops are used as potherb like spinach. The roots are also grown for feeding to livestock during fall and winter. Accidentally, Brassica rapa is closely related to Arabidopsis, and generates relatively large amounts of nectar from its much larger nectaries.
