Heart-leaved, or Blue Wood, Aster makes a lovely addition to any garden and will do best in dappled sun or part shade, although it tolerates almost full shade.
 
By late summer flowers cover this plant attracting all manner of pollinators. Blue Wood also is a larval host to the stunning Pearl Crescent butterfly and of special value to several native bee species.
 
Pinch back stems, or prune, after flowering to avoid self-seeding.
