Crambe
Crambe comes from the Greek krambe meaning 'cabbage', referring to it being part of the Brassicaceae family. Often good, large, foliage plants and producing many 4-petalled often white, flowers, during spring. C. maritima is the edible seakale, long grown in kitchen and vegetable gardens. The leaves are better 'blanched', which can be achieved as with rhubarb, by covering with a forcing pot.
