Cincinnati's indoor desert is the home of many cacti, including succulents. These plants have the ability to store water for long periods of time. Arid conditions, cool winters, and a hot summer sun bring the desert plants into colorful spring bloom.

Of the thousands of species of succulents, the Krohn collection contains such representative groups as the Yuccas, Agaves, Aloes, and Crassulas. From the cactus family, there are the Cereus, Pereskia, and Opuntia or "prickly pear" cactus.

Beyond the desert area is the Orchid Display and behind it is the Floral Display House.
