Once the plantation home of a wealthy rice planter, these 67-acre Gilded Age gardens are surrounded by huge lawns, serene lakes, and wooded gardens that hold just about every kind of azalea in existence. The blooms are at their height in the early spring, but even when they're faded, this is a lovely spot. Unveiled in 2007, an open-air greenhouse is home to some 20 native species of butterflies, and visitors can watch them as they take flight. Guides are on hand to give you tips on re-creating a small-scale butterfly garden in your own backyard.
