Prostanthera cryptandroides

Family: Lamiaceae

Prostanthera cryptandroides is a small shrub reaching a height of one metre.

Young growth is sticky. Mature leaves are elliptical leaves to ovate, about one centimetre long and very aromatic.

Flowers are 1.5 centimetres long, white to lilac with a purple-spotted throat. Flowering is conspicuous and profuse between September and April.

There are two subspecies: P. cryptandroides ssp. cryptandroides and P. cryptandroides ssp. euphrasioides. The former has limited distribution and is found in the Central Tablelands and Central West Slopes of NSW. The subspecies is considered to be vulnerable and is protected in Wollemi National Park and Gardens of Stone National Park.

The latter subspecies has much wider distribution and is found from north Queensland to northern NSW.

The main visible difference between subspecies is the lack of glands on the calyx and branches of P. cryptandroides ssp. cryptandroides.

In the garden

P. cryptandroides is an attractive small shrub to use in native cottage gardens and rockeries.

Tip pruning is necessary to maintain foliage density and abundant blooming.


Propagation from cuttings usually presents no problems.
