Hybrid Perpetuals combine repeat flowering with large flowers, excellent scent and strong colours. They are hardier than Teas, but do seem to suffer badly from powdery mildew.
Hybrid Perpetuals are tall, narrow, upright plants. The flowers are repeat, double and fragrant and grow on the top of the bush. Deadhead and light summer trim to encourage repeat flowering. The vigour of many Hybrid Perpetuals is not always reliable so resist heavy pruning. In winter shape the bush by reducing some of the older wood, which has been weighed down by flowers. Because of its upright nature, it is very difficult to obtain a good shape. Remove all dead, damaged and diseased wood and twiggy bits.
