precocious African lily

A clump-forming, evergreen, herbaceous perennial producing narrow, strap-shaped green foliage, to a height of around 80cm (32in) and a spread of around 60cm (24in). Hemispherical heads to 12.5cm (5in) in diameter, of clear blue, funnel-shaped flowers are produced in late summer on straight, green stems up to approximately 1.5m (5ft) 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
