Cactus flowers in the spring are a big draw for us coming to Tucson, Arizona from March to June. The hedgehog cactus start first in March, then pincushion start to bloom, later barrel cactus, prickly pear, cholla and eventually the saguaro by May. We left at the beginning of April and the barrel, cholla, and prickly pear were loaded with buds and about to bloom, still too early for saguaro.
