Feather-top Rhodes Grass, it's a weed.

Good one, Tropi., 'cause I got no idea, never seen it before, but then I'm an oooold city-slicker.!

Thanks, Tropi. I guess that this must be an immature inflorescence. I have seen many specimens of windmill grass around, but never paid much attention to them. A grass is a grass, is a grass, etc. This one just stood out

I do a lot of work on weeds, particularly tropical ones. Although this one is fairly widespread. Sometimes I wish I didn't know so much about them. Then I wouldn't be spending so much time trying to rid my place of what many people think are "only just plants".

The lot of the gardener, T., my main problems are 'Farmer's friend' (cobbler's peg), Wandering Jew and onion weed; the rest I can keep under control with Zero 490. Oh, and also common couch, and in the lawn, bindies!
