Golden-yellow flowers are produced throughout the warm months on Indian summer gloriosa daisy (Rudbeckia hirta 'Indian Summer'), a cultivar derived from native North American species. Butterflies love to visit the flowers for their nectar, while various seed-eating songbirds flock to the dried flower heads for ripe seeds in fall. Plant this one in full sun, and water only enough to establish the plant root system; then kick back to enjoy.
