Description

Aster azureus is a beautiful clump-forming perennial with pale-blue daisy-like flowers. It blooms from late summer to autumn.

 

The Aster genus produces a large number of floriferous perennials, in all colours, for spring, summer or autumn, for all kinds of uses and growing mediums. Autumn hybrids, tall or small, will benefit from being divided every 2 to 3 years to regenerate the stump and protect them from powdery mildew.
