Okay this a dumb question, but I figured someone here could give me a quick, simple answer: I have a little hunting property in Central Virginia, which is next to a hay field. While there yesterday I noticed all this stuff growing in the filed that looked kind of like small cattails, so I stopped for a closer look. Some kind of millet. Why? I mean I get it, it's grass and can be cut for hay, but aren't all millets annuals? In which case why plant it in a hay field?
