Pennisetum villosum is a species of flowering plant in the grass family Poaceae, known by the common name feathertop grass or just feathertop. It is native to northeastern Africa and parts of the Arabian Peninsula, and it is grown elsewhere as an ornamental plant. It can sometimes be found growing wild where it has escaped cultivation. This is a perennial grass growing in rhizomatous clumps, producing erect stems up to about 75 centimeters tall. The inflorescence is a panicle of clustered spikelets surrounded by a cloudlike mass of plumose white bristles up to 5 centimeters long.
