About this weed

This weed is another rampant, perennial climber with pretty pink, purple or white pea shaped flowers, usually in racemes. It is native to Europe but was probably introduced as a garden plant or as a seed contaminant.

Description

It is a perennial climber with purple, pink or white flowers from November through to January. It can reach 6 feet or more by means of its twining tendrils, but in open areas sprawls. Reproduction can be by seed or by vegetative reproduction from its taproot and rhizomes. It is frost-hardy and long-lived. The foliage becomes rather ragged and yellowish by the end of summer.

Impact on Bushland

If left will spread over bushland and impact on ecological processes and plant communities.

Location

Perennial Pea prefers partial or full sun. It is seen on roadsides or in damp depressions across a few areas of the South-West Province, usually on sandy or lateritic soils.
