    Self-seeds and readily crosses with other Rudbeckias. Resultant presentation is a yearly surprise.

    Black-eyed Susan (Rudbeckia hirta) 'Prairie Sun' is an all-yellow cultivar. I discovered that it is one of the parent plants of R. hirta 'Denver Daisy' when my 'Denver Daisy' failed to return, but suddenly in its place the next year was a beautiful exemplar of 'Prairie Sun'!

    As this example demonstrates, Rudbeckia hirta is a biennial or short-lived perennial that stays in the garden through self-seeding. Native to the eastern and central United States, It brings considerable ecological benefits to the North American garden. It is a larval host plant for the Silvery Checkerspot Butterfly and, in the central U.S., for the Gorgone Checkerspot as well. It is an excellent source of nectar for butterflies and is a Monarch Way Station plant. It attracts native bees (longhorned, leafcutter, cuckoo, bumble, sweat, green sweat, and small carpenter), and also attracts beneficial insects, including bee wolves, soldier beetles, bee flies, and syrphid flies, which consume a variety of common garden pests.

    'Prairie Sun' is a desirable flowering plant. It is a short-lived perennial that is best grown as an annual. Beautiful and colorful in the garden. Unique with the yellow and green cones. Can be planted in a container as well as in the ground. Stunning if grown in massed quantities. Deadhead the faded flowers to encourage more flowering. Deer and rabbit resistant. Drought tolerant, once established.

    2003 AAS Flower Award Winner. Gold Medal winner at the 2003 Fleuroselect trials in England.
