Similar species
Brassica elongata (elongated mustard) is a perennial herb that is native to Europe and Central Asia. Over most of its alien range, impacts of its presence are not yet known, but in a few areas Brassica elongata has competed with native flora for resources. Brassica elongata has the potential to spread over large areas, especially in disturbed habitats.
Species Description
Brassica elongata is a biennial to perennial plant with erect stems up to 1 metre tall. The basal leaves are pinnately lobed to shallowly toothed; the stem leaves are much reduced, and do not clasp the stem. The petals are 6-8.5mm long. The fruits are 1-4cm long, with a stalk-like base above the sepal scars and a seedless narrow beak. (Stace et al, undated).
The Euro+Med Plantbase Project (2006) lists five subspecies of B. elongata: B. elongata Ehrh. ssp. elongata, B. elongata ssp. imdrhasiana Qu├ęzel, B. elongata ssp. integrifolia (Boiss.) Breistr., B. elongata ssp. pinnatifida (Schmalh.) Greuter & Burdet, and B. elongata ssp. subscaposa (Maire & Weiller) Maire.
Brassica elongata is cultivated in Estonia (EME, undated) and is considered a potential gene source for improving quality in rape crops (ARS-GRIN, 2006).
Habitat Description
Young et al, in discussing the distribution of Brassica elongata along US Highway 50 near Eureka, Nevada, US says that \"the remarkable part of this distribution is the rugged topography and variety of plant communities it encompasses.\" The Eureka, Nevada distribution also includes areas of salt affected soil, highly variable annual precipitation, and considerable change in elevation. (Young et al, 2003)
On the Great Basin rangeland, in the US, Brassica elongata \"produces abundant seeds that germinate over a wide variety of constant and alternating temperatures.\" (Young et al, 2003). Germination of B. elongata seeds is, however, extremely limited at very cold seedbed temperatures. The ability to germinate at these temperatures is a competitive advantage for other exotic species on the Great Basin rangeland. (Young et al, 2003)

General Impacts
In Poland, Brassica elongata invades disturbed habitat and has competed with native vegetation for resources and displaced a few xerothermic plants (Mirek, undated).
