At Sabino Canyon, the cacti usually start blooming after the wildflowers. On March 24th, I found a Saguaro cactus blossoming on a sunny hilltop.
Two days later, I noticed that some of the prickly pears were starting to bloom.
I didn't find any cholla cacti blooming, but this one's buds looked about ready to burst.
