[From "Suckering Roses Revisited", by Darrell g.h. Schramm, pp. 23-27]
Among the Portlands I find four roses that cautiously amble away from home—never far. These are ‘Delambre’ (1863), ‘Duchesse de Rohan’ (1847), ‘Indigo’ (1830), and ‘Rose de Rescht’ (reintroduced in 1949).

('Duchesse de Rohan', 'Duc de Rohan') c. 1860. Description and vital statistics. Many-petalled flowers fade slightly with age from rich, warm pink to lavender, exuding a charateristically heady, Centifolia perfume, and occasionally repeating, which is, of course, untypical. It could be an early Hybrid Perpetual.
