A native of Arizona and California, and extending southwards into Sonora and Baja California, this species of the genus Bursera develops a thick trunk with light gray-brown bark and finely pinnate leaves. We grow this species outside in Tucson, where it withstands 25F; heavier frost actually sculpts the plants into a nicer, more compact form. Our seedlings are in one-gallon pots and stand about a foot tall.
