April is the time to see the cactus blooming. But these amazing flowers usually only last for one day - or sometimes only one night. Once you see the buds it may only be a matter of a few days before those buds grow into full flowers and then bloom over. So if you see the flowers consider yourself fortunate. If you see the flower buds, keep an eye on those because they may bloom in the next day or two. They grow fast and end fast. Here are some pictures from the Rabbit Run rock garden.
