Eight species of the genus Brassica have been recorded as weeds in Western Australia. The members of the genus are informally known as cruciferous vegetables, cabbages, or mustard plants. The yellow flowers are arranged in elongating clusters at the tips of the branches (i.e. pedicels), 7-20 mm long, and are held in an upright (i.e. they are lyrate and pinnatifid or pinnatisect). Its elongated fruit (2-6 cm long and 2-5 mm wide) have two compartments and end in a tapering 'beak' 4-10 mm long.

"Our research has opened the way for deployment of the introgressed resistance genes from wild weedy Brassicas into a wide range of high-yielding cultivars, of B. juncea initially and, subsequently, into canola and other crop and horticultural Brassica species," he said. Suitable pH: acid, neutral and basic (alkaline) soils. I am pretty certain that the last posted plant from New England was Brassica rapa and not Brassica oleracea. In fact, by 2005 about three-quarters of the most famous wildflower areas in California and Arizona were overrun with this species. In the USA, wild turnip (Brassica tournefortii) suppresses native desert wildflowers by monopolising the available soil moisture and fruiting before native species have begun to flower. These fruit are borne on moderately long stalks (i.e. Salisbury, P. 2006 Biology of Brassica juncea and potential gene flow from B. juncea to other Brassicaceae species in Australia.

In its natural home on stony, low-nutrient soil, wild cabbage grows very slowly, but in good They also have six stamens, consisting of stalks (i.e. Measures blocking hybridization would prevent or reduce biotic or environmental change caused by gene flow from genetically modified (GM) crops to wild relatives. Plants usually have several upright (i.e. This species reproduces only by seed, which are often spread in contaminated agricultural produce. It tends to expand over larger areas when drought suppresses other annual species and increases fuel loads and fire hazards in desert scrub communities. Leaves are glabrous, fleshier and thicker than other species of Brassica. Alrighty folks, here it finally is, back by popular demand! It can grow to a height of 1 m but usually 70 cm.
