An evergreen shrub that grows about 1m x 1m and is very fast growing with large softly textured heart shaped leaves. It produces masses of attractive pyramidal spikes of pink or bluish-mauve flowers in summer. Cut back after flowering to encourage new growth. It is drought resistant and does well in deep or dappled shade. Rub the stems on a windowsill to repel flies. This is the larval host plant for Bush Bronze, Mocker Blue, Eyed Pansy, the March Commodor and the African Leaf Commodor butterflies. The name is derived from the Greek plektron = a spur; anthos= a flower. These plants have conspicuously spurred flowers.
