Today's Edwardian-style glass structure was built in 1929, but fell into neglect until 1970, when a group of concerned citizens preserved it.

Debate in the community had some suggesting the site would make "a perfect parking lot", but the volunteer actions of the Citizens Committee for the Conservatory saved it from that fate.

Woody plants in this room include olive, etrog, fig, date palm, bay[clarification needed] and pomegranate.

The rainforest collection includes Anthurium, aroids, banana, cycads, dracaenas, ferns, fig trees, Monstera deliciosa, palms (lady, fishtail, fan, and Canary Island date), papaya, Peperomia, Pilea, spider plants, as well as a pond with koi, goldfish, and turtles.

The Conservatory collection includes agave americana, commonly known as the century plant for the long decades until it blooms.
