General Culture:
Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Best in full sun. Tolerates both moist and dry conditions. Performs well in hot and humid summers. Foliage may be pinched back in early summer to stimulate new growth. Shear stems after flowering to encourage a possible fall rebloom. Plants may self-seed in optimum growing conditions.
Noteworthy Characteristics:
‘Blue Star’ is a clump-forming perennial that is noted for its long summer bloom of daisy-like flowers (1” diameter) featuring light blue rays and yellow centers. The flowers are very similar in appearance to those of aster and boltonia. Plants typically grow to 12-18” tall. Oblong-lanceolate green leaves (to 3-4” long). Synonymous with Boltonia incisa ‘Blue Star’.
Problems:
No significant insect or disease problems. Watch for root rot in poorly drained soils.
Uses:
Mass or small groups in borders, rock gardens, cottage gardens or wild areas.
