Botanical Name

RUDBECKIA hirta 'Indian Summer'

Plant Common Name

Common Black-eyed Susan, Gloriosa Daisy, Indian Summer Gloriosa Daisy

General Description

These have some of the largest flowers of all the gloriosa daisies. The enormous golden yellow blooms of 'Indian Summer' have typical “black eyes” and are great for cutting.

Common black-eyed Susan is a short-lived perennial that is native to much of North America. In summer this clump forming plant puts forth thick leafy stems topped with large daisies with yellow petals and brown-black central cones. These attract many pollinators, such as bees and butterflies.

This ornamental grows best in full sun and well-drained average soil. It is prone to root rot and powdery mildew, so it's best to provide it with good air flow and avoid overwatering. It is wonderfully easy to grow and is well placed in wildflower gardens, cutting gardens and mixed borders. Deadhead it regularly to encourage continued bloom. Like many Rudbeckia it will self-sow gently. Seed eating birds enjoy eating its dry seedheads and help spread the joy.
