Symphyotrichum lateriflorum
Symphyotrichum lateriflorum is a species of flowering plant in the daisy family Asteraceae, native to eastern North America. In the British Isles it is still widely referenced under its old name, Aster lateriflorus syn. A. diffusus, A. vimineus.
Growing to tall by wide, S. lateriflorum is a clump-forming herbaceous perennial with alternate, simple leaves on stiff, hairy, purplish stems. Small white or pale lilac composite daisy-like flowers are borne in corymbs up to across in late summer and fall.
Like other asters, this plant is valued in gardens for providing late colour after the main flowering season has finished. The cultivar S. lateriflorum var. horizontale has gained the Royal Horticultural Society's Award of Garden Merit.
