What is this plant? It is about 30-36 inches tall, doesn't appear to be clumping but there are patches of it here and there in my ditch. I live in zone 8a, southeast coastal NC.
Looks like on of the Andropogons, maybe Andropogon glomeratus.
ummm....interesting. After looking at pictures of a number of varieties of Andropogon, I'm thinking perhaps
Maritime Bushy Bluestem, Bushy Beardgrass (Andropogon tenuispatheus) although it could be Common Bushy Bluestem (Andropogon glomeratus var. glomeratus)...but the pics of the Maritime Bushy looks more like it.
Definitely Andropogon anyway!
