Faits intéressants

Western Silvery Aster is distinguished by its silvery, hairy leaves and stems. It produces daisy-like flowers in shades of lavender, violet or pale purple with yellow centres from late summer into fall. The silvery foliage is an adaptation to dry, sunny conditions and gives the plant an attractive appearance even when it is not flowering. It is an excellent choice for a rairie garden, dry border, sandy garden or sunny slope. It forms a relatively compact clump and is generally well behaved. It is very drought tolerant once established. It requires excellent drainage, particularly through winter. It does not need rich soil as overly rich soil can encourage weak, floppy growth.
