And here, still more, from the Atlanta Botanical Garden.
If you've never been, you ought to go. Atlanta's worth seeing anyway, as it's a big city with lots of things in it. Go in the morning, before the air gets too hot, and wear a little bug spray, should the mosquitos grace you with their presence, and enjoy your time among the flowers.
(And if you get too hot, just duck into the Highlands Room, where the brisk mountain temperatures will cool the sweat on your skin, and quails will scurry along the floor and coo at you from behind the shielding plant fronds.)
