Prostanthera cuneata
Alpine mint bush is a compact, aromatic shrub from high mountains of south-eastern Australia, grown for its pale lavender flowers. It needs well-drained, gritty soil and a cool, sunny position.
Prostanthera cuneata, commonly known as alpine mint bush, is a species of flowering plant in the mint family Lamiaceae, and is endemic to mountainous areas of south-eastern continental Australia. It is an erect, compact shrub with egg-shaped leaves with the narrower end towards the base, and pale lavender to almost white flowers with purple blotches.
In cultivation this plant has gained the Royal Horticultural Society's Award of Garden Merit. It has an RHS hardiness rating of H4 (hardy throughout most of the UK, down to -5°/-10 °C) and is suited to USDA hardiness zones 8 to 9.
Alpine mint bush occurs in alpine and subalpine closed heath and shrubland in granite-based soils in New South Wales and Victoria, often in association with snow gums (Eucalyptus pauciflora). In Tasmania, the species is listed as "presumed to be extinct" under the state's Threatened Species Protection Act 1995. In New South Wales it is found south from the Brindabella Range and in north-eastern Victoria at altitudes between about 1,500 and 2,000 m (4,900 and 6,600 ft).
