The richly diverse ecosystems of the Florida Keys can be discovered in hidden gardens, tucked off main thoroughfares and the Overseas Highway, throughout the 125-mile-long island chain.

Connect & Protect Florida KeysNames of Florida Keys subtropical trees, plants and flowers often are mysteriously lyrical, with monikers such as “gumbo limbo,” known as the “tourist tree” because of its peeling red bark (really!), and “lignumvitae” — Latin for “wood of life,” whose dense bark contains a resin used for treating arthritis.

Hidden gardens, nurtured and enjoyed by Keys locals, protect and preserve rare and exotic trees, plants and flowers. And they’re open to the public, providing behind-the-walls access, during winter garden tours. Exploring these spots is a rare treat that lets visitors make a meaningful connection to the island chain’s natural world.
