Crazyflower, it's a short lived perennial here, but cuttings take easily, which can be overwintered in a cold frame, GH or windowsill. Dordogne is usually colder than the UK in winter, often down to -7° to -10°. And we can have hard frosts and snow and violent rain! Summers are longer and hotter than the UK. Can be difficult to cope with when growing an English herbaceous border.
