They are frost tender, min 7-10C. They will prefer full light and fertile well drained soil. You should water freely when in full growth and moderately at other times. Cut back stems by half to three-quarters after flowering to maintain a neat habit.
You can propagate by softwood cuttings in the spring or by greenwood or semi-ripe cuttings in the summer.
