Agapanthus praecox subsp. minimus

A clump-forming, evergreen, herbaceous perennial, producing narrow, strap-shaped, green foliage to a height of around 30cm (12in) and a spread of around 30cm (12in). Loosely hemispherical heads of pale blue, funnel-shaped flowers, are produced in late summer on straight, green stems from 40-60cm (16-24in) high. As an evergreen species, it is more frost tender than the deciduous types and requires protection from frost in winter, especially when grown in colder areas
