common crupina USDA PLANTS SYMBOL: CRVU2
Crupina vulgaris Cass.
Synonym(s): bearded creeper

Common crupina is a Federal Noxious Weed and is native to southern Europe. It is a winter annual that grows 1 to 4 ft. (0.3-1.2 m) tall. Leaves are entire to finely dissected (leaves become more divided towards the apex) and up to 6 in. (15.2 cm) long. Flowers are purple to pink, long, slender (vase-shaped) and bloom from May until soil moisture is depleted. Common crupina begins as a basal rosette and eventually develops alternating dissected leaves that are rough to the touch. Dense populations of this plant can invade grasslands, pastures, rangelands, forested areas, canyons, riparian areas, roadsides and waste places in the western United States. It reproduces by seed. Grazing (deer or livestock) or cutting can stimulate lateral branching, thereby increasing flower and seed production.
