This pachycaul tree is from Brazil and Argentina. Once in the genus Chorisia, this species is known for its photosynthetic trunk bearing large, blunt spines. The leaves are green and multi-fingered, and the flowers are pink to purple. This plant is common in the southern California landscape, but the most extreme frosts in Tucson (23F or lower) will kill it. These plants are seedlings in one-gallon pots.
