Boone Hall Plantation, just outside Charleston, has a very good rose garden designed by Ruth Knopf. Also, in town, right by the gates to the Citadel, is Hampton Park, which has the Noisette Study Garden plots. I believe they are still there, although it's been a few years since I've visited.

Just wanted to remind anybody that is coming to the Meetup tonight in Charleston SC @ the Library on 68 Calhoun St. 7pm, it is still on! Hope to see somebody there! LOL Darren

Agardenstateof mind - it probably is Deep Cut Gardens though the name doesn't ring a bell. Is it the one with the old hemlocks in back of the main house with the stairs going down? I surprised no one has mentioned it here before unless I just missed it. Birdgardner, thanks for the update. I wanted to recommend Arnold's Promise so I'm glad you got it. The scent is great and the blooms glow. I have Diane as well but I have been disappointed in mine. It doesn't bloom well though I can't say that about other Diane's I've seen. I just got a dud and I am thinking about shovel pruning it. Also, although I've caught a scent off it once or twice over many years, it mostly doesn't have a scent. As far as combo's, winter jasmine, helleborus foetidus, early purple, blue or yellow bulbs like iris reticulata and crocus, any evergreen, cornus winterflame, kerria and other colorful stems. There is a beautiful display at Brooklyn with a the collection of witch hazel heavily under planted with purple crocus tommasinianus and it's gorgeous.

For historic gardens go to Middleton Plantation and Drayton Hall. Both are large landscapes that are quite significant historically speaking, not small gardens with lots of flowers. Well worth the time if you are interested in history and gardens.
