Bowles Mauve is a long-blooming evergreen perennial with slender grey-green foliage and mauve-purple flowers that bloom nearly year-round in mild climates. As a sterile hybrid, it won't self-seed aggressively, making it a reliable ornamental for sunny garden spots.

Why grow it

Bowles Mauve Wallflower offers extended bloom periods compared to many temperate wallflowers, often flowering from late winter through summer in mild climates. Its sterile hybrid status reduces volunteer seedlings in garden beds, making it easier to manage than fertile wallflower species. The grey-green foliage provides year-round structure, and the plant tolerates poor, well-drained soils typical of sunny sites where many ornamentals struggle.

Watch out for

This cultivar performs best in mild climates and may decline or die back severely in areas with sustained freezing temperatures or heavy snow. Flowering can diminish or stop entirely during hot, dry summers, and the plant benefits from afternoon shade in regions with intense heat. Stem rot may develop in poorly drained soils or during extended wet periods, so site selection and soil preparation are important for longevity.
