ISOTOMA Creeping Star 'Gemini Blue'
 
The fine, delicate texture of both the flowers and the evergreen leaves brings a calming, gentle impact to the garden in hanging baskets, pots or rockeries. Also ideal as a weed-suppressing groundcover in the border. Isotoma axillaris ‘Gemini Blue’ forms a gently cascading mound, reaching a height and spread of 30cm. Plants bear open, powdery-blue, starry flowers from May through to October. Alongside six months of blooms, an extra, sensual element is given by its sweet, subtle perfume as it drifts across the garden, attracting bees and butterflies. 
 
Native to Australia, these perennials love the sunshine, so make sure you plant them where they receive plenty, in any aspect except north-facing. Isotoma axillaris ‘Gemini Blue’ also likes moist, well-drained soil, so heavy clay is best avoided. 
 
A half-hardy, evergreen perennial that is often grown as an annual in the UK, plants can be overwintered away from frost and reinvigorated the following spring.
