Hi Tobysmum,

You can certainly leave them outside through much of the year, and that will generally be the best place for them, providing much better light levels than they would ever receive indoors.

They are marginally frost hardy and should be allowed to enter a period of winter dormancy when you'll need to give them a little more protection.

There's a good site with masses of info, including on soil, watering and dormancy at:

They won't eat greenfly unless one happens to land on them though :-)
