Greenhouse and Sonoran Plant Garden

Since the inception of the Desert Laboratory, researchers have taken a keen interest in growing plant specimens of special interest. In fact, the Lab’s 1906 greenhouse in the first greenhouse in Tucson, which was recently rehabilitated and is once again thriving with life. Our living collection represents the unique bio-cultural diversity of the Sonoran Desert region and features the tropical affinity of the Sonoran Desert flora as well as species from continents with similar habitats that harbor plants that look nearly identical to our native species but are unrelated (convergent evolution).

 

The Lab maintains three primary living collections, (1) the Desert Laboratory Greenhouse, (2) the Sonoran Plant Garden, (3) The Tumamoc Resilience Garden Shade house.

Some plants bear the name of the founding scientists of the lab, or close colleagues and friends:

- Agave felgeri (Felger’s Agave, from the costal desert near San Carlos, Sonora): Named for eminent botanist of the Sonoran Desert, Richard Felger.

- Agave shreveii (Shreve’s Agave, from the northern Sierra MAdre): Named after previous Lab researcher and Director Forrest Shreve who mapped and established our concept of the Sonoran Desert region.

- Bursera exequielii (Exequiel’s Bursera, endemic to Punta Arena and Cabo Pulmo, Baja California Sur): Named after ecologist and conservationist Exequiel Ezcurra, a leader in the region’s conservation and ecological understanding.

- Echinocereus gentryi (Gentry’s Hedgehog Cactus, found in the Sierra Madre near Alamos, Sonora): Named for pioneering botanist of tropical Sonora, Howard Gentry

- Fouquieria shreveii (Shreve’s Ocotillo, only found in the Chihuahuan Desert in the Bolson de Mapimi): Named after the first to map the Sonoran Desert region, Forrest Shreve

- Tumamoca macdougallii (Tumamoc Globe Berry, found through much of the mainland Sonoran Desert, though consistently rare): Named after Tumamoc Hill and founding director Daniel T. MacDougall
