This year I am going to buy some more plants and place them under all the bedroom windows. The plants don't normally have a very long life span...ours are at least five years old and spent their first few years in pots. I am careful to prune them after (or during ;) flowering and that helps prevent the bushes from getting spindly and awkward. But that is really all they need...quite good from a water perspective as they thrive on good drainage and enjoy their root area well mulched...lovely plants. Here are some photographs...
Bye now,
