I moved all these zygo cactus to water them and to rearrange the window where I had them. When I saw them all together (and this is only my collection of smaller ones. My larger ones have their own window) it dawned on me that perhaps my collection was getting a little bit out of hand. Will I stop buying them? Doubtful.

I can’t seem to limit my collecting, either! I just came home from the grocery store with an Easter rhipsalidopsis gaertneri even though I’ve promised myself that I will not buy any more. I couldn’t resist. Your collection looks gorgeous!
Phyllis,
So glad to hear that I am not alone! Thanks for reading and commenting. Karla
