Beautiful Fragrant Australian Native
One of the standout features of Round Leaf Mint Bush is its highly aromatic foliage. Brush against the leaves and they release a fresh mint-like fragrance, making this an excellent plant beside pathways, entrances, patios and frequently used areas of the garden.
During spring, the foliage becomes covered with masses of delicate mauve-purple flowers, creating a spectacular seasonal display.
Growing Prostanthera rotundifolia
Plant in full sun or part shade in well-drained soil enriched with organic matter. Regular watering during establishment will encourage strong root development, while established plants appreciate additional moisture during extended hot and dry periods.
Mulching around the root zone helps retain moisture and protects the shallow root system, particularly during Melbourne’s warmer summer conditions.
Pruning Round Leaf Mint Bush
Light pruning immediately after flowering helps maintain a dense, compact and attractive shape. Regular tip pruning when young can also encourage additional branching and produce a fuller shrub.
Avoid cutting heavily into old woody growth where possible. Maintaining consistent light pruning generally produces the best-looking plants.
Perfect for Native and Cottage Gardens
Round Leaf Mint Bush works beautifully in both Australian native and traditional cottage-style gardens. Its soft foliage, aromatic leaves and abundant flowers combine particularly well with other flowering native shrubs, ornamental grasses and smaller groundcovers.
It can also be planted as an informal hedge or screening shrub, providing greenery and seasonal colour without requiring the rigid maintenance of a formal hedge.
Add Fragrance and Native Colour to Your Garden
Prostanthera rotundifolia is an excellent choice for gardeners wanting something more than just another green shrub. Its combination of fragrant foliage, beautiful spring flowers and naturally bushy growth creates year-round garden interest while providing the resilience and character expected from an Australian native.
