Blue Star

Amsonia tabernaemontana · Perennial

Blue Star is a slow-growing perennial, hardy in USDA zones 3-9, that matures to about 2–3 ft × 2–3 ft. It does best in full sun and part shade with medium water needs in well-drained, moist and occasionally-dry soil. Expect blue blooms in spring. It attracts butterflies and pollinators, stands up well to deer and drought and grows happily in containers.
