| Puncturevine is an annual, low-spreading forb native to the Mediterranean. Leaves are opposite, hairy, 1-3 in. (2.5-7.6 cm) long, and divided into 8-18 oblong leaflets. Flowering occurs from midsummer to frost, when 5-petaled, yellow, ½ in. (1.27 cm) wide flowers develop singly in the axils of the leaves. Fruit are circular, spiny burs that split into 5 sections. Burs can cause injury to bicycle tires, bare feet, and even small truck tires. Plants invade roadsides, pastures, fields and other disturbed areas. Plants are toxic to sheep and other grazers. |
