Er, my mate says it's ok to grow it but beware of nosey neighbours. It's a beautiful plant and wonderfully fragrant. Should Mrs Schweizer have a problem, it'll soon turn into your problem. The harvested value of mature plants can be several thousand Franks.
Loads of people have it growing on balconies (roof terraces are best, ahem) and I've heard from my mate that the best fertilizer is one part fresh urine and five parts water. Apparently urine contains the right combination of phosphates etc. But I wouldn't know about that...
