Rosa 'Souvenir de la Malmaison' is a rose cultivar with large, very pale pink flowers that open flat.
[2] 'Souvenir de la Malmaison' has few thorns and grows to between 1 and 2 metres (3.3 and 6.6 ft) high and about 1 meter (3.3 feet) wide.
The plant has a reputation for lack of winter hardiness (USDA zone 6)[4] and for responding poorly to pruning.
In colder, rainier climates, the cultivar can be susceptible to mildew and black spot.
There are five known extant sports: the climber 'Climbing Souvenir de la Malmaison' (Bennett, 1893), the pink form 'Capitaine Dyel de Graville' (Boutigne, 1905[5]), a lighter pink sport with scooped petals 'Mme Cornelissen' (Cornelissen, pre-1864[6]) the white sport 'Kronprinzessin Viktoria' (Volvert, 1887), named after the oldest daughter (1840–1901) of Queen Victoria, and 'Souvenir de St Anne's (Hilling, 1950), a semi-double white rose with yellow stamens that had originated in a garden at St Anne's, Clontarf, Dublin.
