About Lathyrus venosus Muhl. ex Willd.
Lathyrus venosus Muhl. ex Willd. is a perennial vine with herbaceous stems, growing from a creeping rhizome. Its stems are either climbing or sprawling, and reach 0.9–1.2 metres (3–4 feet) in length. The leaves are alternate and even-pinnate, usually bearing 8–12 leaflets, and end in a branched tendril. Each leaflet is roughly oval, untoothed, and hairless. Papilionaceous flowers grow from leaf axils in clusters of 8–15, arranged in a raceme, and are generally pink, purple, or blue. The fruit this plant produces is a hairless seedpod. This species grows naturally across most of southeastern continental Canada and eastern continental United States. Its typical habitats include pine and prairie woodlands, stream banks, rocky slopes, roadsides, and sandy ground.
