New England aster, Symphyotrichum novae-angliae, features rich color highlights in the late season of early frost and colorful trees. The blue-purple blossom is eye-catching with its yellow-orange center. This large and showy aster, like most asters, blooms late in the season and provides a critical fall nectar source for pollinators, especially monarch butterflies as they stock up for their fall migration to Mexico. It is the larval host for pearl crescent and checkerspot butterflies.
