ISI 2021-14. Cyrtocarpa edulis Standl.

This little-known, pachycaulous tree resembles another Baja species, Bursera microphylla. The common name of “Elephant Tree” for the latter could equally apply to Cyrtocarpa edulis in reference to its succulent/woody, swollen trunks. These are sufficiently succulent so that even 6" ø cuttings can be rooted. Native to southern Baja, Cyrtocarpa edulis is less cold tolerant and, therefore, not as widely grown. Besides its obvious appeal to succulent collectors, the name edulis refers to the edibility of its fleshy fruits, which have a slightly sweet, custardy quality, but make more of an impression by their aroma, which is strikingly similar to that of freshly buttered popcorn. We offer HBG 138889, plants grown from self-fertile seed by Gene Joseph of Plants of the Southwest from material originally collected in the La Paz area of southern Baja California, Mexico. Gene covers his shade house in which his parent plant grows for the winter so that it is protected from frost. However, he can vouch for its heat tolerance to 115° F. $15.
