Peniocereus greggii

Arizona Queen of the Night is our most illusive flowering cactus. The majority of the time, it looks like dead sticks so they are almost impossible to spot. During my many hikes and also while surveying flora in the McDowell Sonoran Preserve , I have found several specimens. It’s been extremely dry so a portion of this one has already become dehydrated but, as you can see, there are several buds so I’m hopeful. Although they start blooming at night, the flowers can last til early morning as evidenced by a friend who captured one during the early morning at Tohono Chul Park in Tucson.
