Portland rose André Dupont, gardener to Empress Joséphine, received this rose from England in 1803 and was calling it Rosier de Portland by 1809. It reached him despite the continental blockade, perhaps given a fair wind by the duke of Portland who held high government office. For a rose with Damask and Gallica parents its red colour is unusually bright. There was speculation that this was due to genetic input from a Chinese red variety, but this has been discounted by DNA tests. A pinky red 'Portland' known since the 1770s appears to be a different rose.

The Portland Rose, 'The Scarlet Four Seasons Rose'. Likely the results of a China rose-gallica cross. Resembles gallica 'Officinalis'. Originally known as 'Paestana', taken from the Italian town of Paestum, a centre of rose propagation for the insatiable Roman market -- for which roses were even grown under glass to lengthen the season when blooms would be available. Dupont named it 'Duchess of Portland' and it became the founder of the Portland rose line -- though many people continued for some time to refer to it as a damask perpetual in reference to its long and comparatively continuous flowering period. It was listed in a nursery catalogue in 1782. Redouté pictured it under the title Le Rosier de Portland.

The Portland Rose Redouté did a portrait of 'Le Rosier de Portland'. Description... flowers: in clusters, bright crimson, rather darker and more intense than the Red Rose of Lancaster, but smaller and semi-double. In hot dry seasons there is a long pause without flowers after the first flush at midsummer, but with good cultivation and reasonable moisture there are further flowers in autumn. Not strongly scented. Hips are long and are of true Damask shape.

Portland Rose Parentage: Unknown, but reputedly 'Quatre Saisons' x 'Slater's Crimson China', with possible R. centifolia involvement.
