Alliaria

 

a genus of biennial plants of the family Cruciferae. The leaves are entire; the radical leaves are reniform and longpetioled. The flowers are white and gathered in racemes. The fruit is a capsule. The plants emit a strong garlic odor. There are about five species, distributed in the temperate zone of Eurasia. The USSR has two species. A. petiolata (formerly A. officinalis) grows in shady forests, shrubbery thickets, and in ravines; it also is a weed in parks, orchards, and gardens. The plant is used as a seasoning in place of garlic. The leaves contain vitamin C, and the seeds contain a fatty oil. The seeds can be used as a substitute for mustard. The milk of cows that have eaten A. petiolata acquires a reddish yellow color and a caustic aftertaste.
