They will take several seasons to reach their full potential. Primarily, make sure that they are well fed. A liquid feed every week while they are in active growth will help. Also, if they become rootbound in their hanging basket then you may need to carefully repot them into fresh compost. You can also pinch out the tips of their stems to make the plants produce bushier growth (this will reduce the length but should encourage a fuller display).
In winter it is important not to overwater try to keep the compost just moist as this will reduce the risk of root damage should the compost become frozen. Overwintering in an unheated greenhouse is ideal as they prefer cool conditions (A heated environment will produce very spindly growth). In spring they can be acclimatised to outdoor conditions over a week or so and then moved outside.
