Tatarian Aster Aster tataricus3.jpg Aster tataricus Perennial Full sun Drought tolerant Well-drained 3-8 Late autumn Winter Aggressive spreader Insects Tatarian Aster is a tall, upright perennial native to Asia but grown elsewhere in gardens. Description The plant overall is coarse, with large leaves and thick stems. The flowers are borne in late autumn, with yellow disk florets and purple ray florets. The species can grow up to 2.5 m (8 ft) tall, but shorter cultivars are available. Growing conditions Does best in full sun. Plants tend to flop if grown in very rich soils. Hardy in USDA zones 3-8. Uses Generally grown as a "back of the border" plant, for its tall flowers in the fall. Excellent as a cut flower. Maintenance Cut back half-way in mid-summer to encourage bushiness. The plant spreads aggressively, so will need to be reined in by digging out the outer crowns or dividing every two or three years. The plant does not readily self-seed. Propagation Easily divided.
