Sweet pea shrub is many-branched and grows up to 2 m high. It has alternating leaves which are oval and up to 30 mm long. Pea-like purple or veined-purple flowers are clustered in simple racemes at the ends of the branches.


Sweet pea shrub rapidly colonises forest margins, coastal cliffs, shrublands and dunes, competing with and inhibiting regeneration of native species, primarily in northern New Zealand. It is also drought-tolerant.
