Larry, sorry that I don't have an answer for you.

Ken, I don't let it get to flowering stage! It's like a weedy grass, but it is somewhat fine bladed with sort of sharp edges and maybe a bit of a midrib iirc (not going out into the wet to look around for any I missed), and the basal foliage is purplish red. They have real roots, no bulbs. And what seems to be happening, is that if you leave even the tiniest bit of root behind, it keeps coming back. Earlier this spring I thought I had beaten it in one of the beds, but nope... I found a bunch yesterday. My best guess is that it is an invasive perennial, but I have no guess as to whether or not it is a native (because the presumed source of it, compost or mulch, could have come from who-knows-where). I looked at the Calflora images, but they weren't helpful. Maybe next time I am out with a camera, I will think to try to take a picture.
