Rudbeckia hirta "Indian Summer" (Gloriosa Daisy, Black-Eyed Susan)
I first discovered this showy perennial Black-eyed Susan several years ago at a nursery where they were selling them as annuals and for fifty cents apiece. I am not one to pass up a bargain, so I bought several, and I'm glad I did, too. Not only is "Indian Summer" not an annual and, although often called a biennial, it hung around my garden for at least three years, and that's actually a pretty good run even for a perennial. Showier (and more long-lived) than the species, "Indian Summer" has large, bright yellow flowers with a purple/brown central disk and blooms its head off from June until frost. It is interesting to me that this received one negative comment in a gardening forum, and it is because it failed to return the following year for someone who planted it. Come on! That's not the plant's fault! This colorful Black-Eyed Susan is ideal for borders, cottage gardens, and for naturalizing. "Indian Summer" grows from two to three feet in full sun and well-drained soil in Zones (3?) 4-10. Be sure to deadhead regularly to keep those blooms coming.
