I have no green thumb. The only plants that do well for me are those that need either a lot of water or no water. I am always pleased when one of my cacti blooms like this one did. If you remember, I 'deflowered' one of my cacti last year when my tripod fell over on it. I took no chances with this one; used a long lens and no tripod.
Today is my mother's 86th birthday! Happy Birthday, Mother! Beginning of summer, too!
