Unknown 'tumbleweed' grass ID help

treeguy123(AL 7b)January 9, 2008

On windy days the entire panicle of this strange and cool grass will detach, roll, and blow threw the air every winter. If it's a very windy day they can take flight and reach 20 to 30+ feet in the air before blowing into the woods. Each detached panicle that blows threw the air is around 1.5 to 2 feet long but a few can be up to 3 feet long. I'm guessing this it's the neat way it disperses it's seeds. I've nicknamed it tumbleweed grass, :-) and it's bugging me because I want to know what it's really called.

Does anybody know what exactly what this interesting grass is called? Any help would be very appreciated.

Anybody know?
I've been thinking it's in the genus: Eragrostis but I'm not 100% sure.

Panicum capillare?

I looked at Panicum capillare before but I don't think that is it because it is shaped different, the seed structures look different, and the panicle looks thicker. But Panicum capillare does detach and roll around like tumbleweed just like our mystery grass from what I've read.

Here is a link that might be useful:

To maybe help, I've narrowed it down to these as being good matches. If anybody has more, post them. Or if anybody knows what exact type of grass it is for sure.

Eragrostis capillaris
Eragrostis elliottii
Eragrostis hirsuta
Eragrostis lugens
