This hybrid was discovered and developed by Mark Dimmitt at the Arizona-Sonora Desert Museum in Tucson, Arizona.

Believed to be a natural hybrid of Parkinsonia aculeatae, Cercidium floridum, and Cercidium microphylum, it combines the desirable characteristics from the three parent trees.

Very popular due to its thornless characteristics. Not easy to find in nurseries. The natural occuring Parkinsonia aculeatae has very sharp thorns.
