Perennial pea

Perennial Pea (Lathyrus latifolius), also known as broad-leaved everlasting-pea, is a species of flowering plant in the legume family, Fabaceae. It is native to Europe but has been introduced to other parts of the world as an ornamental plant.

Description

The Perennial Pea is a herbaceous perennial plant that grows up to 2 meters tall. It has a robust, climbing growth habit, with tendrils that help it to climb over other vegetation. The leaves are alternate, pinnate with two leaflets, and end in a tendril. The flowers are large, pink to magenta, and borne in racemes of up to ten on a long stem.

Distribution and Habitat

The Perennial Pea is native to Europe, but it has been introduced to other parts of the world, including North America and Australia. It is often found in disturbed areas, such as roadsides and waste places, where it can form dense stands. It prefers well-drained soils and full sun.

Cultivation and Uses

The Perennial Pea is often grown as an ornamental plant for its attractive flowers. It is also used in erosion control due to its robust growth habit and ability to form dense stands. However, it can become invasive in some areas, outcompeting native vegetation.

Ecology

The Perennial Pea is a host plant for several species of butterflies and moths, which feed on its leaves. It also provides nectar for bees and other pollinators.

Toxicity

Like many members of the legume family, the Perennial Pea contains toxic compounds, including a neurotoxin called ODAP. Ingestion of large amounts can cause a condition known as lathyrism, which can lead to paralysis.
