Dolichos Pea

This is climbing woody, herbaceous perennial which becomes woody towards the base. The soft green stems climb over nearby structures, shrubs or trees, and can grow up to 2m tall, extending a long way horizontally if possible. Its leaves are dark to medium green above, paler below and are composed of three diamond shaped leaflets which have a wide set base before tapering to a fine point. Each leaflet has its own stalk. The flowers are typical for the pea family and are pink, mauve, magenta and purple in colour, growing on the tips of new growth stems in short, dense racemes with long peduncles. Flowering occurs throughout spring and summer, i.e. August to January in its native South Africa. The pods are flat and sickle-shaped, each containing four to six seeds, and are formed soon after flowering. In warmer climates this is an evergreen, but it may develop a deciduous habit in areas where are subject to frosts.

The seeds are explosively thrown out of the ripe pods landing some distance from the parent plant and they are able to remain dormant in the soil for some years.

It is an invasive weed in Australia
