Brassica oleracea palmifolia

DC.

Brassicaceae


This species has been cultivated as a food crop for many hundreds of years and, in that time, several quite distinct forms have arisen. The nomenclature of these forms is confused, to say the least, and by no means universally accepted. We have followed the treatment used by GRIN, though it is very likely to be revised in the future[

General Information

Jersey kale is a biennial plant derived in cultivation from the wild cabbage. It usually grows up to 3 metres tall, exceptionally to 5 metres, producing an unbranched stem topped by a rosette of leaves.

Propagation

Seed - sow in a seedbed outdoors in mid spring. Plant out in summer as space allows. Do not let the seedlings get overcrowded or they will soon become leggy and will not make such good plants. If your seedlings do get leggy, it is possible to plant them rather deeper into the soil - the buried stems will soon form roots and the plant will be better supported.
