Ornamental Millet (Pennisetum glaucum) is a nice surprise for gardeners out for the unusual. This variety is probably 'Purple Majesty,' named an All-America selection in 2003. It grows to 5 feet tall and flower heads add another 8-12 inches. Its long, slender leaves turn purple with maturity and exposure to the sun. It's easy to grow, heat-and-drought tolerant, and grows in sun or part shade, producing the deepest color in full sun. By the way, birds love the seed.
