Sea Kale
NEW ARRIVAL for 2026
Crambe maritima
Native to the seashores of England and Ireland and popular in Victorian England. Once grown on a large scale as a winter substitute for asparagus, cultivated for its blanched tender delicate ivory-colored leaf stalks that can be boiled or steamed to provide a good source of vitamin C.
Sea Kale grows up to 3' forming a beautiful rosette of wavy-edged thick silvery-grey leaves and dense racemes of small white sweet-scented flowers in midsummer.
Plants die back in the winter. This is the ideal time to take cuttings of the fleshy side-roots to store in moist sand until setting out in soil in March. Taking cuttings to produce more plants is a faster way to generate plants than starting each year from seed.
Scarify seeds or nick the big seed casings for better germination. Start indoors like broccoli, set out, protect to overwinter and begin harvesting the 2nd and subsequent years.
