Wood's blue aster is a reliable fall-blooming aster. It has lavender blue flowers from late summer to early fall. It is a compact plant with dark green leaves. Earlier in the growing season, the leaves create a nice mound of green leaves
Wood's blue aster has been a nice fall bloomer at the Xeriscape Garden. It spread through underground stems to form a moderate sized clump. Once the rabbits discovered this plant, they have eaten it regularly.
Cut old stems to ground level in late winter or early spring. Divide clumps every few years to maintain the plant's vigor.
