Lathyrus lanszwertii [7] is a species of sweet pea known by the common names Nevada sweet pea or peavine. It is found in western North America from California to Texas to British Columbia. It is a tender vining perennial which bears lavender, fuchsia, or white pea flowers, and pods containing inedible peas.
The leaves are pinnate with two leaflets and a terminal tendril, which twines around supporting plants and structures, helping the sweet pea to climb. In the wild plant the flowers are purple, 2–3.5 cm (3 ⁄ 4 – 1 + 1 ⁄ 2 in) broad; they are larger and highly variable in color in the many cultivars. Flowers are usually strongly scented.
Leaves are made up of several leaflets of various shapes up to 4 or 5 centimeters long. The leaves usually bear coiling tendrils and the stipules may be large or small. The inflorescence is a showy array of up to 15 pea flowers, sometimes densely packed together, and usually some shade of bright violet, light to medium purple, or white.

The bacterial phytopathogen Rhodococcus fascians has been demonstrated as one cause of fasciation, such as in sweet pea (Lathyrus odoratus) plants, [7] and in lilies (Lilium longiflorum), [8] but many fasciated plants have tested negative for the bacteria in studies, [9] [better source needed] hence bacterial infection is not an exclusive ...
