Brown mustards is widely cultivated for its edible seed which is used to make the condiment 'brown mustard' and is also sprouted as the mustard of mustard and cress. It has only 70% of the pungency of black mustard (B. nigra) but can be harvested mechanically so is more viable commercially. This species has also been cultivated in the Orient for many hundreds of years and a wide diversity of forms has been developed with edible leaves, stems, roots and seeds. These forms have been classified by the botanists as follows and separate entries have been made for each of them.
B. juncea crispifolia. The curled or cutleaf mustards, this group has attractively curled edible leaves. B. juncea foliosa. The leaf mustards have quite large smooth-edged edible leaves. B. juncea japonica. Rather similar to B. juncea crispifolia and combined with that group by some botanists. B. juncea multiceps. The multishoot mustard group. B. juncea napiformis. A form with a swollen edible root. B. juncea rugosa. Large somewhat cabbage-like edible leaves. B. juncea strumata. A form with large edible leaf stalks. B. juncea tumida. A form with swollen edible stems.
Plants take from 2 - 5 months from sowing to maturity, depending on the season and the cultivar. They prefer a fairly high stable temperature and are well adapted to short day length. Many are best grown in warmer climates than Britain but there are several cultivars that grow well in this country. Plants have a rooting depth of between 90 - 120 cm.A good bee plant.
