What is it? Constructed in 1893, the steel-and-glass Phipps Conservatory and its surrounding grounds house the Center for Sustainable Landscapes, an impeccably green botanical research facility.
Why go? Take the right-turn-only path that meanders around the Victorian greenhouse and grounds and through the numerous plant collections and exhibits, including desert plants, ferns, orchids and the butterfly forest. Come in the summer for the Gardens of Sound and Motion flower show, where wind sculptures and interactive installations add another dimension to the blooms.
