Helping You Become a More Successful Gardener
RUDBECKIA hirta 'Irish Spring'
Common Black-eyed Susan, Irish Spring Black-eyed Susan
The large-flowered ‘Irish Spring’ has marvelous bold bright yellow daisies with emerald green eyes—a far cry from your typical black-eyed Susan. It is easy to grow, great for cutting and offers lots of blooms in the heat of summer.
Common black-eyed Susan, also called gloriosa daisy, is a short-lived perennial that originates from North America. It is wonderfully easy to grow and blooms for an extended period of time. Throughout the summer, the clump-forming, short-lived perennial puts forth, thick, leafy stems topped with colorful flowers that attract pollinators such as bees and butterflies. The pretty daisies are radial, colorful and have green central cones. Deadhead regularly to encourage continued bloom. If the seed heads are left to dry, they will attract seed eating birds.
Rudbeckia hirta grows best in full sun and well-drained, average soil. It is prone to root rot and powdery mildew, so space it well to encourage good air flow and allow its soil to dry between watering. This popular ornamental is at home in wildflower gardens, cutting gardens and mixed borders. Like many black-eyed Susans, it will self-sow gently.
