Pitahaya agria (Stenocereus gummosus) is common on most of the peninsula, and there are a few populations on the mainland too. It is widely regarded as bearing the most delicious of all cactus fruits.

Organ pipe cactus (Stenocereus thurberi) occurs almost throughout the peninsula as well as on the mainland from southern Arizona into Sinaloa. The plants on Cerro Colorado are mostly small.

A few small Yucca valida grow on the very perimeter of the Cerro Colorado study area. The flowers (inset) appear in summer.
