Symphyotrichum ciliolatum (formerly Aster ciliolatus), commonly known as Lindley's aster and fringed blue aster, is a perennial herb native to Canada and the northern United States. It is also known as ciliolate wood aster and northern heart-leaved aster. The common name Lindley's aster honours John Lindley who first described the species in 1834.

Description

Symphyotrichum ciliolatum can reach heights of up to 1.2 metres (3 feet 11 inches) and can spread via long rhizomes. The leaves are typically heart-shaped with winged petioles. Flowering occurs between late July and October. The ray florets are blue or bluish purple, and the disc florets are yellow, becoming reddish purple with maturity.
