Black Eyed Susan
Rudbeckia hirta
The Black Eyed Susan, Rudbeckia hirta, is typically an annual wildflower, but some varieties are perennial or biennial (flowering in its second year, then dying). These native prairie flowers can be found growing wild in almost every state, with the exception of the dry desert areas of the Southwest.
This bright yellow,daisy-like flower grows to a height of 24-36 inches and is excellent to use in cut flower arrangements, and for growing in your Butterfly Garden.
Rudbeckia hirta is also commonly called a Gloriosa Daisy. It is hardy in USDA zones 3-10. The plant is very adaptable to almost any type soil, but should be grown in full sun and watered regularly to achieve the best flowering performance. Deadheading spent flowers will prolong the blooming period considerably.
Perennial varieties of Rudbeckia may be propagated by division during their dormant season. All varieties can be easily grown from seed which should be sown 2 weeks before the last expected frost, or started indoors 6-8 weeks before planting them outdoors in the Spring. Rudbeckia seeds require light to germinate, so lightly press them into the soil surface without covering them up.
