THE NATIONAL GEOGRAPHIC MAGAZINE The Illustration Magnifies Diameters PURPLE-TOP (Triodia fa'va) Purple-top is a perennial growing to the height of 3 to 5 feet, with smooth, flat leaves. It is found in dry fields from southern New York, the Ohio Valley and Missouri southward. It is a very showy grass with large panicles of flowers which occur in 5- to 7-flowered spikelets. The glumes, or husks, are deep purple and shining, and the feathery stigmas almost brown, standing out in strong contrast against the bright green of the stem and foliage.
