Probably will be difficult to find at local nurseries, unless they stock a number of native plants and then they may not have it, as it isn't native anywhere west of the Miss River.
Your best solution may be ordering online. Be sure to check ratings for any source at Dave's GardenWatchDog, before ordering.
Be aware that the plants are somewhat difficult to transplant, as they require several hours of sunlight and constant moisture, yet good drainage.
I have tried, with limited success, several times, mainly due to the moisture requirement and it makes me mad, since a neighbor has a large patch growing in the middle of his lawn (from my seed!) that he can't get rid of, due to bits of the runners left behind, when he digs it up.
Hope you are able to get it established and enjoy it!

Thank you, I'm very aware of online resources. I'm looking for a local source. Are you in Georgia? How did you stumble onto this forum? Sounds like I need to send your neighbor some postage and have him send me some runners....
