Cape gooseberry? Cant spell Physalis

I've grown those in the past but they tried to takeover the greenhouse! I did manage to keep them going for a good few years though in a compost filled dustbin.
If I could find a more compact variety, I may give them another try  as I enjoyed the fruit in the paper lanterns.

There is a dwarf one - not sure how different it is. 
I like growing them because they're so easy. I have 2 in buckets as we speak.
