ʻJenny Duvalʼ and ʻBelle de Crécyʼ, classified either within the Gallica or within the Hybrid China roses (Beales, 1985; Beales et al., 1998; Cairns, 2000; Dickerson, 1999), are found in the same branch together with the two Gallica  accessions R. gallica L. ʻConditorumʼ Diek and R. gallica ʻOfficinalisʼ Thory.

Jenny Duval ('Jenny') Gallica. Duval (France) before 1836... Claimed by some to be the same as 'Président de Sèze'; however, when correctly identified, these are two distinct roses... The blossom color -- changing with age and temperature -- may appear as rose-pink violet, lavender, or mauve-gray, so that no two flowers ever seem quite the same... Growth is upright but the canes may bow or arch under the weight of the flowers... Possibly a Gallica-China hybrid.

Jenny Duval Gallica. Before 1842. Shrub: normally rather upright for a Gallica; some prickles and bristles. Foliage: medium green; quite large foliage, elliptical, often only 3 per leaf. Bloom:nsolitary or in clusters of 2 or 3; medium size, semi-double; center petals folded, quartered, visible stamens; petals reflex slightly towards the inside. Colour: veined pink at the centre, more lilac on the periphery, with numerous shades which give the bloom a lighter impression; when the bloom agespasses to a greyish lilac which seems to cover the rose.
This rose raises a lot of questions. Much of the contemporary literature assigns it the date of 1821 but doesn't provide information about who the breeder was... This rose was first listed in Van Houtte's catalog of 1842. A couple of years later, Oudin described it in his catalog as "medium, very full, white with a pink center". This colour is very surprising. In effect, A. Otto, in his "Der Rosenzüchter oder die Cultur der Rosen" (erlangen, 1858, p. 212) describes as: "bright red".
The American Rose Society believes that 'Jenny Duval' is the same variety as 'Président de Sèze'. This is also very surprising...According to us, 'Jenny Duval' and 'Président de Sèze' are two different varieties and have never been synonms....'Jenny Duval' as exhibited at Sangerhausen, for example, is not identical to 'Président de Sèze'. It is clearly less double and the periphery of the bloom is darker.

('Jenny Duval') Confusion reigns over this rose. In the first edition of Classic Roses (1985) [Beales] wrote of it as a cultivar in its own right. By the time [he] wrote Roses (1990) [Beales] had come to believe that commercial stock was synonymous with 'President de Seze'. Now [Beales is] not so sure. [Beales explains and says none of the modern descriptions] conform to the old description of crimson-to-mauve.

'Jenny Duval'. Gallica. One of the most remarkably colored roses in existence. It usually opens pale lilac, but as the flowers expand they are apt to take on every shade of purple, magenta, pink and violet that you can think of, all in the same flower, and all quite separate, but without stripes or blotches.
