Various paddle cactus - I can tell you the one on the right is a Cow's Tongue Cactus.
For loved ones in CO, something you'll rarely see - a lizard crossing Rabbit Ears Pass. Bottom left is a Fire Stick Cactus.
Ocotillo in full bloom on the left. The cactus on the right was "in the pink" and bare, all within a week's time.
This grand old sentinel of the garden seems to be saluting the end of the desert bloom. Here's hoping your May is already bringing the blooms promised by those April showers (and snowstorms), and that your own colorful display is starting as ours is ending.
