Description

Very little is known about this variety of prickly pear cactus. About a third of the historic occurrences have been extirpated and the remaining populations are highly fragmented. This is due to habitat loss caused by agricultural development in the region in the early 1900's. Continued development along with several industrial and recreational activities still threaten the remaining populations. This variety grows in dense patches with many of its leaves overlapping with neighbors, making accurate individual counts difficult. This plant is measured as collections of pads that all appear to root at the same location or clusters to deal with this difficulty. When this cactus flowers in May, the patches become beautiful fields of large pink blossoms. (Brown and Cypher 1997)
