Rudbeckia hirta Indian Summer

Indian Summer Black Eyed Susan

Indian Summer Black-eyed Susan (Rudbeckia hirta ‘Indian Summer’) is grown for boldly scaled golden flowers. Broad petals surround a dark center, and individual blooms can reach nearly 5 inches across, giving a few plants considerable presence in a summer bed.

Upright, bristly stems carry the flowers above simple green leaves. This is a short-lived plant, classed as a biennial, with its main value in a strong seasonal display through summer and early fall rather than a permanent woody framework.

Provide sun or light shade and soil that holds some moisture without staying waterlogged. Water new plants regularly while roots establish.
