Flower: The 2-lipped labiate flower have 2-upper lobes and 3-lower lobes and appear solitary or in pairs or three together in the leaf axils during early spring. The colour is mauve to white with purple spots in the throat.

Fruit: The tiny nutlets are in groups of 4 and are enclosed in the persistent calyx. The small seeds are viable but the plant is commonly reproduced vegetatively.
