P.petraea.JPG (23041 bytes)Prostanthera petraea: is a member of the Lamiaceae family. This rare species was named in 2006. Some botanical publications, prior to 2006, list this native Mint Bush as Prostanthera species B. The species is found in Boonoo Boonoo National Park and other areas around Tenterfield on the Northern Tablelands of New South Wales. The species grows together with the white-flowering form of Prostanthera nivea. It is unusual to find two Prostanthera species growing together in the wild.

Prostanthera petraea is a small to tall shrub. The leaves are ovate with prominent stalks, up to 8 centimetres long, 2 centimetres wide and strongly aromatic. Leaves are dull, olive-green above and paler beneath. The lobed flowers are 2 centimetres long, white, carried in terminal sprays and appear in spring and early summer. Blooms are conspicuous and profuse. They are similar in colour and size to the flowers of the better known Prostanthera lasianthos.

Both foliage and flowers are attractive features.

Prostanthera petraea deserves to be widely cultivated. Not only because it is a handsome shrub but also because of the species rarity in the wild.

This native Mint Bush would be an interesting addition to a native shrubbery.

Propagate from cuttings.
