I uploaded this photo of a cactus I saw outside of JBWS to iNaturalist, and despite what I thought was a detailed description, I got no response. So I did a bit of searching on my own and narrowed it down to being either the Engelmann Prickly Pear or the Barbary Fig. I eventually came to the conclusion that it was an engelmann prickly pear, because in all of the photos I saw of barbary figs they were a bit taller than this cactus is. This cactus originates from Mexico and is still found in Northern Mexico, as well as throughout the south-central and southwestern United States. This cactus typically flowers in late April and into May, and what I found really interesting is that each bloom lasts only one day. The flowers open up in the morning around 8 am and close, 8 hours later. This plant really knows how to take it easy!
