The answer to last week’s mystery is broomsedge, Andropogon virginicus, pictured in photo #2.
The plant’s distinctly flattened leaves and sheaths turn reddish-brown with maturity, while the flowers and seed heads give a feathery appearance. In Winter, the foliage and seed heads develop a pleasing golden orange color.
On late Winter afternoons, a field of broomsedge is quite a spectacle with glowing coppery foliage and silvery hairs that refract the sunlight.
