I think if you contact the Georgia Chapter of the American Chestnut Foundation they can give you that information. They are looking for people to grow them and find new sources of indigenous Georgia trees that can contribute pollen to the breeding program. They do have some, of course, but want more. Most of the previous breeding has been using sources from outside of Georgia for pollen and mother trees. Their next step is to breed indigenous Georgia genes into them to create southern crosses. By the way, Martin said that the chapter annual meeting will be at Berry College this year. He said keep an eye on the website for more details - I think it will be in May. Here is a link that might be useful: Georgia Chapter, ACF

I never felt that information put out by Tina Samuels was very accurate. She did a native plant book for Georgia that had issues in the content. While those are certainly good plants, I would not describe them as top ten plants for Georgia even in the world of native plants. Georgia is a huge state and no single list will do for the range of environments we have.

Most of these land-grant universities have good agricultural programs that assist the local communnities with information.

I now believe this is a Pityopsis graminifolia (Narrowleaf Silkgrass) and thankfully it is native. I probably repotted it in a soil mix that is too rich and moist and that's possibly why it hasn't flowered. Thanks for the posts!
