grass ID please?

This is one of a kind here so either it is rare or it escaped from someone's garden miles away. It has narrow leaves and delicate purple flowers...beautiful! I'm in Northern VA (cove forest, Appalachians).

Looks like one of the rosette grasses, Dichanthelium sp. Should have smaller leaves in a rosette at the base of the plant,otherwise it is a Panicum sp. If Dichanthelium it is likely one of the narrow-leaved species such as D. linearifolium or D. depauperatum.

I don't see a rosette...so I'll go w/Panicum.

Thanks Lycopus!

No, I think you're right...it looks more like a Dichanthelium sp but I can't find a description with the purple flowers...you'd think this would be part of a description....it's a fairly distinct feature? I can't really see rosettes on either species you mentioned but I'm probably missing something? If it helps this was found in a limestone/meadow/forest edge setting. Thanks!

Also just re-examined...stems are fuzzy....pubescent. Dead stalks from last yr but def. no rosette.

My bad, the two species I mentioned are among the few that don't form the rosette leaves. It is probably D. linearifolium. I don't think the color of the flower is unique any species.

Ok....I see, everything has purple flowers :) Just found a key for Dichanthelium and every other one had purple flowers! I will go w/your ID of D. linearifolium.....I hope it spreads!

Thanks again!
