Prostanthera cuneata
alpine mint bush
An Australian native, this is a compact, aromatic, evergreen shrub with small, lustrous rounded leaves. From June to August, clusters of tubular, pure white flowers with distinctive purple and yellow markings appear. It is ideal for a sheltered, sunny, mixed or shrub border and looks particularly good among silver-leaved plants or strappy phormiums.
How to care for Prostanthera cuneata:
After flowering lightly trim or prune any shoot that spoils the symmetry of the plant. After pruning apply a generous 5-7cm (2-3inch) mulch of well-rotted garden compost or manure around the base of the plant.
