A couple of months back I did a post on search for the perfect plant pot. It's not just aesthetics that are important when thinking about keeping succulents though; the most common discussion is terracotta verses plastic. Something I think is as important is the size and shape of the pot as it is another myth that all succulents do fine with restricted root systems. Getting the pot wrong can really slow the plants growth down, which in some cases can be an advantage but not if you are actually wanting your plants to grow.
Apart from speed of growth the other area where pot size may make a difference is in producing offsets. There are some people that think that restricting root space means plants produce more pups, others say over-potting encourages it. For me the jury is still out; I have plants that pup profusely and others that don't pup at all and I am a long way from being able to say how pot size effects this. The only way pot size effects pups for me is in easy of removing and spacing. But as I tend to remove pups at the start of each spring when I re-pot this doesn't make much difference. I would love to hear if anyone has noticed anything one way or another.
Of course water and climate usually have a far bigger effect on the speed of growth than pot size. But in the UK where we don't have the very hot summer, or intense sun light every little bit helps.
