Candelilla
Euphorbia antisyphilitica is a succulent that offers an interesting structural form. Pencil-thin stalks grow about one foot tall and spread as a clump about 2 feet wide. In spring, tiny pinkish-white flowers cover the tips. It is drought-tolerant and withstands a range of sun exposures, including full or reflected sun to partial shade. It must have well-drained soil or it will rot. When cut, it exudes a milky white sap that is poisonous so where gloves when handling.

University of Arizona News
Researchers from the University of Arizona and an independent naturalist teamed up to report that as temperatures rise, plants are flowering at higher elevations than in previous years. They compared 93 plant species over two 10-year periods, using the naturalist's extensive field notes. The changes have the potential to impact food sources for insects and animals.
