Brassica oleracea asparagoides
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[
Common Name: Nine Star Perennial Broccoli

|Other Uses Rating
Prefers a position in full sun in a well-drained fertile preferably alkaline soil[
]. Prefers a heavy soil. Succeeds in any reasonable soil. Succeeds in maritime gardens[
Plants do not often live for more than 3 - 5 years[
Immature flowering head - raw or cooked[
]. The plant forms a small cauliflower head in early spring. When this is harvested, another 6 - 12 smaller cauliflowers are produced on sideshoots[
]. The plants are not highly productive, but they are well-flavoured and make an excellent vegetable[
Leaves - raw or cooked. They have a mild cabbage flavour and can be harvested all year round, though be careful not to weaken the plant and thereby reduce the yield of flowering heads[
Grows well with celery and other aromatic plants since these seem to deter insect predations[
]. Grows badly with beet, tomatoes, onions and strawberries[
An extract of the seeds inactivates the bacteria that causes black rot[
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.
