I need a greenhouse or some such thing as my back windows just aren't the best for plants but it's all I have for now.Typically, the smaller, shorter succulents have evolved to be this way because they have the sun blasting on them. There definitely as many species to consider, but most of them will grow a little leggy if put in less sun, or just die (typical with harder to care for plants, which I will not be recommending).
I'd say look into sedum, anacampseros, crassula (although you'll have to trim those back to keep the compact look), and mammilaria
Thanks for these suggestions, I am going to go do some research on them!
. That's a separate thing that I wouldn't know about, since I've never had my whole collection in an enclosed space
I then made a big wire box and put cacti and flowers in it and the squirrels climbed all over it to get inside. Pack rats eat EVERYTHING that contains water, and I don't doubt mice do the same. I can't be sure about deer but they eat everything in my garden so I need a well protected area to grow anything.
