Rudbeckia hirta

Spacing: 1 per square foot. Mature height: 2-3 ft.

Pollinator & wildlife value

NC State Extension's plant toolbox names it as a larval host plant for Wavy-lined Emerald and Silvery Checkerspot caterpillars specifically, and notes American goldfinches eat the seed heads in fall: the same two relationships as coneflower, since both are common companions in the same native-meadow plantings.
