Red Fescue Poaceae
Festuca rubra
I think the small fescue from dry places in the foggy Marin Headlands that I'm most
familiar with is Festuca idahoensis.
http://ag.arizona.edu/classes/ram382/plntpix/feid.html Like caifornica, idahoensis has
a narrow long fountain shaped curve & the leaf is folded or rolled. Often idahoensis
looks more thread like. It's makes a very pretty little dense tuft. I've seen what looks
like very old plants with big six inch trunks on them. Idahoensis is a classic small
bunch grass with bare ground between clumps to make room for wildflowers.
