Yes, I grow a few different succulents, including an assortment of the Asclepiads ~ Stapelia, Huernia, Orbea, Caralluma & Hoya.
I like anything that does not have thorns or stickers. The closest I've gotten to stickers is Bromeliads and I am wary of getting too carried away with them.
And yes, a few years ago my sweetie built me a greenhouse. It wasn't quite what I had in mind but how could I criticize his generous thought and it does work well. I have a wood heater, a church pew, chairs, a potting table... on those dreary winter days I love to go sit out there and dream of spring.
