Established in 1935, this unique habitat is the only frost-free botanical garden in the continental United States. You won't see fancy topiaries and exotic plants, but you'll see a unique eco-system that naturally occurs in this area and the Caribbean. There are paved walkways that take you past butterfly gardens, mangroves, Cuban palms, lots of birds like herons and ibis, and ponds where you can spy turtles and fish. It's a nice respite from the sidewalks and shops, and
offers a natural slice of Keys paradise.
