Portland roses

Although many of the Portland roses were probably grown at Malmaison in France, they got their name from the English Duchess of Portland. She sent a plant to the château at Malmaison and the gardener there, Andre Dupont, called the first rose of the group after her. The origin of Portland roses is debatable but they were probably bred form a China x Damask cross. They repeat flower, although less reliably than the modern Hybrid Teas, and grow to around 120 cm (4 ft). The flowers, which retain a strong Damask scent, are on short stems so that, when open, they tend to be closely surrounded by the leaves.

Portlands hate too hot weather and love rather cool summer climate. In southern Sweden they are magnificent to grow and because they are very hardy they can survive the coldest winters there. 
All make a rounded shrub of 120X100 cm or 4 X3 feet. Partial shade is tolerated. Deadheading after flowering will ensure next flushes. We prune them only lightly. Always remove dead and weak wood. Portlands are very suitable for growing into pots and as a short hedge. In the center of the border they combine beautifully with perennials. Great garden plants!
