Plectranthus Parviflorus ‘Blue Spires’ (Blue Spires Plectranthus) is a compact Australian native shrub with soft, felty green leaves edged in creamy white. From spring through autumn, upright spikes of pale blue to violet flowers rise above the variegated foliage, adding soft colour and vertical interest. Its neat clumping habit makes it ideal for garden borders, underplanting beneath taller shrubs and trees, mass planting, and decorative containers.
Easy to grow and adaptable, ‘Blue Spires’ performs across a wide range of light conditions from full sun to full shade. Once established, it is heat tolerant and relatively waterwise, while occasional trimming keeps the plant compact and encourages fresh growth. Its combination of attractive foliage, long flowering period and low-maintenance nature makes it a useful choice for both native and mixed garden designs.
