Even in the middle of winter you can soak in the sights and scents of the tropics under the domes of this Victorian glass conservatory. The greenhouses shelter cacti, fruit trees, palms, and orchids. The American Ivy Association certified the claim of the largest ivy collection of any botanical garden in the world. Formal gardens and a park with a golf course (the park is popular with runners) surround the conservatory. Guided tours are given by reservation.
