Prostanthera Ovalifolia (Purple Mint Bush) is an attractive Australian native shrub with lush green, oval-shaped foliage and masses of beautiful mauve to purple flowers in spring. Its foliage can release a pleasant minty aroma when brushed or crushed, adding extra appeal when planted beside garden paths.
Fast-growing and evergreen, Purple Mint Bush is ideal for garden borders, informal hedges, screening and native gardens. It thrives in well-drained soil with regular moisture and performs well in full sun to part shade, particularly with some protection from harsh afternoon sun. Prune after flowering to maintain a dense, attractive shape and encourage fresh growth.
