Cactus Collection

I bought these five cactuses from Lowes on clearance. I really didn't know what to do with them, but they were either $0.88 or $0.48 each - and they didn't look bad either. I potted them up together in one pot and I thought they looked nice for a while - one recently bloomed, but they're starting to look crowded. I had amassed a small collection of ceramic pots that I never knew what to put in them - so I figured this would be a good idea. I tried to match the cactus to the pot, taking into account size, shape and color. I'm happy with the outcome and so is Robin. Now I don't know where t o put them!
