Brassica oleracea asparagoides

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[

Propagation

Seed - sow in a seedbed outdoors in mid spring. Transplant into their permanent positions as soon as the plants are large enough and there is space in the garden. 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.
