RUDBECKIA hirta 'Denver Daisy'
Common Black-eyed Susan, Denver Daisy Black-eyed Susan
Named to commemorate the city of Denver, Colorado’s 150th anniversary in 2008, ‘Denver Daisy’ has large, golden daisies with chocolate brown centers and marks at the base of each petal. That year the city distributed 300,000 packets of seed for this Ernst Benary cultivar with mixed results. Regardless, this lovely garden flower performs well, is exceptionally heat tolerant and blooms for a long time in summer.
Common black-eyed Susan, also called gloriosa daisy, is a short-lived perennial that is native to much of North America. It is a warm season bloomer that forms a clump of foliage from which rises thick, leafy stems topped with large daisies with prominent, raised dark-brown or black centers. These make superb cut flowers and attract many pollinators, such as bees and butterflies. Deadhead it regularly to encourage continued bloom.
Grow Rudbeckia hirta in full sun and well-drained soil with average fertility. It is prone to root rot and powdery mildew, so space it well to encourage good air flow. Allow its soil to dry between watering. This popular ornamental is at home in cutting gardens and mixed borders. Like many black-eyed Susans, it will self-sow.
