Hedging my best

It is exactly a year since we planted the hibiscus hedge at Dar Barbara and I am so pleased with it.  A year ago it was 18" sticks planted 18" apart but now it is a proper hedge which we have had to cut twice and even the righthand corner which did not take well and had to be replaced twice is looking like it was meant to be. The recent rain has greened up the garden as well as the surrounding countryside. When we went to Agadir the Sousse valley looked like the Vale of Clwyd in June. The Agave is looking good too and the roses which were about 9" high a year ago are getting out of hand and I will have to think how to prune them - Bush or Standard?
