Lotusland
The 37-acre estate—with gardens that are often ranked among the world's 10 best—once belonged to the Polish opera singer Ganna Walska, who purchased it in 1941 and lived here until her death in 1984. Many of the exotic trees and other subtropical flora were planted in 1882 by horticulturist R. Kinton Stevens. On the docent-led or self-guided tour—the only options for visiting unless you're a member (reserve well ahead as spots fill fast)—you'll see an outdoor theater, a topiary garden, a lotus pond, and a huge collection of rare cycads, an unusual plant genus that has been around since the time of the dinosaurs.
