Prostanthera Rotundifolia (Round-leafed Mint Bush)
Prostanthera Rotundifolia (Round-leafed Mint Bush) is a fragrant, evergreen shrub native to Australia, known for its aromatic, round, glossy leaves and vibrant purple to mauve flowers. The plant produces small clusters of these striking flowers in spring and summer, which attract bees and butterflies. The mint-scented foliage, when crushed, adds to its appeal, making it a great choice for herb gardens, borders, or feature plants.
Round-leafed Mint Bush thrives in well-drained soils, and it prefers full sun to partial shade, making it ideal for Australian climates. It is drought-tolerant once established and requires minimal maintenance, needing only occasional pruning to keep it tidy. With its fragrant foliage, attractive flowers, and resilience, Prostanthera Rotundifolia is an excellent addition to gardens seeking a hardy, low-maintenance shrub with both beauty and function.
