Two very different brassicas keep evolving in two of my baby pool gardens as the plants reseed each spring....I THINK that they both began as either Appin or Purple Kosaitai. One has evolved a long thick CRUNCHY leaf rib that makes for delightful eating raw, the other has evolved a short broad leaf with a very wide and crunchy fan-shaped leaf stem reminiscent of Chinese cabbage. Each spring they flower, shed seeds that germinate the following autumn but that always become a some what different yet desirable veggie!
