Description

Lathyrus is a genus of annual or perennial, herbaceous vines with winged stems and showy flowers in the pea family.  It is often used for animal fodder.  Plant in the full sun in rich well-drained soil.  This plant easily climbs trellises and walls with its tendrils.  It works well in a cottage garden or sprawling down a slope to help stop erosion.  The word lathyros is Greek for pea or pulse. Some species are native to the SE USA; others found here are naturalized exotics.

Insects, Diseases, and Other Plant Problems:  No serious problems.  Apihds, mites, and pea moths are occasional pests.  Slugs and snails can eat new plants. Black root rot, leaf spot, powdery mildew, and rust diseases occasionally occur.
