Peltaria alliacea

About

Peltaria alliacea, or garlic cress, is a perennial flowering plant in the family Brassicaceae. It is endemic to Albania, Austria, Hungary, Romania and former Yugoslavia. The plant grows up to 60 cm (24 in) and has white flowers from May to July. The plant is glabrous (hairless) with simple, entire leaves. The leaves are ovate, sessile and amplexicaule. When crushed they smell of garlic, hence the common name. The 3–4 mm (0.12–0.16 in) long white petals are shortly clawed. The orbicular, very flat silicula or seed, is pendent and has a size of about 6 by 6 mm. Its chromosome number is 2n=14.
