Named after the locality in which it is thought to have originated, Silsden, nr Keighley, Yorkshire. Said to have been bred by Jonnie Watson, an old gardener from the town; our donor acquired it in 1980 from “a chap” who had grown it for 12 years. Only one of his seeds germinated, but since then seeds of the variety have been saved and shared around the whole district! Apparently all of the horticultural show growers wanted it; our donor has won first prize with his specimens. Sow this summer cabbage in March and the small heads with distinctive white-veined, blue-green leaves will begin to develop in July.
