Hungarian vetch

Vicia pannonica, Hungarian vetch, is an annual herb of the Fabaceae family native to southern and central Europe and adjacent western Asia, where it is also widely cultivated as a forage and cover crop. Plants typically grow 30 to 80 centimetres tall, with weak, hairy, somewhat angular stems that scramble or climb over surrounding vegetation using branched terminal tendrils. Leaves are alternate, paripinnate, 5 to 10 centimetres long, with usually six to ten pairs of narrowly oblong to elliptic leaflets each up to 2.5 centimetres long and 5 millimetres wide, bearing soft hairs and a small mucronate apex. The flowers are produced in short axillary racemes of two to four, each papilionaceous bloom about 1.5 to 2 centimetres long; the standard petal is pale yellow to cream, often marked with darker purplish veining, the wings and keel similarly creamy. Flowering occurs in late spring and early summer. The fruit is a flattened, densely hairy legume pod 2 to 3 centimetres long containing several rounded brown to nearly black seeds.
