There are several cultivars of this perennial flower commonly known as the Black Eyed Susan. One of the cultivars you have most likely seen in the landscape and nurseries is R. hirta ‘Indian Summer' which gained popularity in 1995 as a winner from the All-American Selections. It is an herbaceous perennial plant growing between 2-3' high and wide. It is drought tolerant once established and can easily be grown from seed, blooming the first year. It is in the Asteraceae family and has a composite flower in orange and yellow tones with a prominent cone-shaped head. All are native to North America, and mostly have hairy foliage, which is what hirta means. There are so many new varieties to choose from. I have 3 in my garden at this time, and they are stunning with a very long bloom time all summer long, also attracting bees and butterflies. They also make a fabulous addition to fresh-cut floral arrangements. I took a few shots of some of the varieties I am seeing at the nursery and my own. One of the more popular ones I have seen lately is called an Echibeckia, a cross between an echinacea and rudbeckia. However, I don't think it looks anything like an echinacea other than having a cone and daisy-like florets. I would highly recommend either the rudbeckia or the crossed one to anyone looking for a beautiful, super easy plant to grow.
