Additional Info

Can grow up to 8 feet tall with showy yellow daisy-like flowers from mid to late summer into fall. Should be grown with support. Prune plants back in June to encourage branching. It prefers moist to occasionally wet acidic sandy to clay loams in full sun. Give it room to grow and spread and you will have a profusion of late-season flowers when little else is blooming.

Wildlife value: Flowers provide nectar to pollinators from July until the first frost. This is a larval host plant that supports Silvery Checkerspot. Songbirds, mourning doves and small mammals are attracted to seeds so leave standing dead flowers into the winter as natural bird feeders. Members of the genus support specialized bees
