Prostanthera ovalifolia
Also called Oval Leaf Mintbush, Purple Mintbush
Prostanthera ovalifolia, commonly known as the oval-leaf mintbush or purple mintbush, is a species of flowering plant in the family Lamiaceae and is endemic to south-eastern continental Australia. It is an erect shrub with egg-shaped leaves and groups of mauve to deep blue-purple flowers arranged in groups at the ends of branchlets.
This mintbush is widely cultivated as a garden shrub where it typically grows to a height of about 2.5 m (8 ft 2 in). It grows best in a well-drained soil with some protection from direct summer sun. It should be pruned back by about one third to retain its bushy shape.
Oval-leaf mintbush is widespread in forest growing on sandstone in south-eastern Queensland and eastern New South Wales. It is also sporadically naturalised in the eastern half of Victoria.
