This afternoon while watering my office plants, I was surprised to see my cactus is blooming! This cactus was given to me from LaVonne, my former supervisor, who dug it out of the ground in Arizona about five years ago, or so. I left it in the sand from which it came and merely put it into one of my old pots. It sits on a window sill in our office and I water it a couple of times a year, or so. Last year it surprised me with three blooms.
If it follows the pattern from last year, the blooms will last about 2 days. I'm so happy I spotted it today.
