Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
Stamens, got it. Let me look that up! Here is something I learned from my S-I-L. Use a hand lens to get an extreme closeup. So probably not a penstemon. Does that leave only Physostegia?
Sunset Zone 28, AHS Heat Zone 9, USDA zone 8b~"Leaf of Faith"
