Tucson always puts on a lovely show of gorgeous cactus blossoms. The bloom are huge, brilliant colors and brief. Even very small cacti put forth their best "prom" colors to greet the longer days and the high clouds. These two short (about five inches) "Rainbow" cacti (blooming by my front door) have beautiful rose-colored thorns that are small and tightly knit against their green ribs. Their gorgeous flowers bloom with such out-sized confidence and brio, as if to insist that though they are small, they matter.
