Plumbago can make a good informal or formal hedge because it does well with pruning. It will flower abundantly after being cut back, bearing flowers on new wood. Cut back after winter to keep it neat and in the desired shape, even if this is only done every few years. Plumbago will form into trees if not pruned or controlled.
