Small cactus in pots are very popular here in Italy where so many people in the towns and cities do not have a garden and many not even a terrace. The variety is amazing and I am sure if ever I found myself in that position I would become quite passionate about them, Jorun's Euphorbia being top of th list. What an interesting family of plants that is by the way, can't imagine what I would do without some of the varieties I cultivate....
