About

Lathyrus biflorus is a rare species of wild pea known by the common name two-flowered sweet pea. It only grows in Humboldt County, California. It is a member of the serpentine soils flora. This is a petite perennial herb growing thin, tough, fuzzy stems with leaves each made up of two pairs of small linear leaflets. There are tiny bristlelike tendrils. The inflorescence bears two greenish-white pea flowers each up to a centimeter wide. The fruit is a hairless dehiscent legume pod.

Where it grows

The two-flowered sweet pea is endemic to just southeastern Humboldt County in California. There it grows on outcrops of serpentine in Jeffrey pine woodlands at elevations of 1,300–1,400 meters (4,300–4,600 ft).
