'Léontine Gervais' (Barbier, 1903). Rosa wichurana x 'Souvenir de Catherine Guillot'. This famous and popular rambler has often been confused with 'Francois Juranville'; 'Leontine Gervais' is paler and only semi-double. The buds are coppery red, but the flowers open apricot pink and fade to pale pink and cream or white. The petal-backs are slightly darker. The flowers are about 5cm across, very strongly scented of sweetness and musk, and borne singly or in short-stemmed clusters of up to about seven. They become rather loose and untidy towards the end of their flowering and do not stand rain well - they do best in cool climates and keep their colour much longer in the shade. The leaves are wonderfully dark and lustrous, and the growing stems are crimson where the sun strikes them and green beneath. The plant has its big flowering fairly early, with a few more flowers later. It is healthy, sinuous, and vigorous and will grow to 5m.

 Léontine Gervais.  Modern, large-flowered climber.  Apricot blend.   The coppery red buds of this rose open to cupped blooms that develop into semi-double flowers of salmon and yellow that fade with age.   The dramatic trusses gather in clusters of 3-10, and the mixture of colors in the large, fragrant blooms is most attractive.   The young growth is bronzy, maturing to dark glossy foliage.   Easily reaching 20 ft (6m) in 3 or 4 years,  it is ideal for pergolas, walls and trees and will tolerate some shade.  In warm areas it will have some rebloom.   This rose was one of 30 varieties created by Barbier and Compaigne of Orléans, France, during the first quarter of the twentieth century.  Zones 4-10.   Barbier, France 1903.  Rosa wichuraiana x ‘Souvenir de Catherine Guillot’.

Article by Odile Masquelier on the roses at (her home) La Bonne Maison
......Leontine Gervais - there she is! Raised by Barbier, and introduced in Orleans in 1903, much less vigorous than ‘Alberic Barbier’ or ‘Albertine’, Léontine Gervais is probably the name of someone who worked in the Barbier nursery. She is ideal for a large arch or a pergola. Flexible, she will weave in and out to join her neighbours, but she is easily controlled. Foliage that is healthy and glossy sets off medium size, semi-double flowers that are quite loose petalled; they drink in the light and allow a glimpse of their stamens. The round, tight buds of bright coral expand into peachy apricot blooms, creating a very luminous effect, but of a surpassing softness. She is called Léontine, but like Colette, I would prefer to call her Abricotine. To my knowledge no other rambler has this delicious nuance of colour, which blends marvellously with the ivory of ‘Gardenia’ or ‘City of York’ and with the soft but pure yellow of ‘Primevère’, another Barbier rose, alas now forgotten. Leontine will easily achieve 5 or 6m (16.5-20ft, and like all the wichurianas, hates to be confined to a wall that is too warm for her. Arch, porch, gazebo, suit her well and in spite of her rather short flowering season, I could never just walk past this veil of salmon pink on the pergola at the very beginning of June. R. wichuriana x ‘Souvenir de Catherine Guillot’- once blooming.

p15   A good choice for covering a wide area, at least 15-20 ft (4.5 - 6m) would be a rambler like ‘Léontine Gervais’ which has a pendulous and horizontal habit.  
p17   A tunnel requires formal planting and detailed pruning, which means using climbers or the neater ramblers like Noisette Carnée (‘Blush Noisette’)  or ‘Léontine Gervais’.
p18  Where pillars and swags are used together, a delightful combination is to grow ramblers like ‘Léontine Gervais’ on the swags, and hybrid musks like ‘Cornelia’ on the pillars.  
p101  Léontine Gervais.  A good companion to ‘Alberic Barbier’;  habit, foliage and growth all complement each other well.   The flowers are predominantly pink, well filled with petals that have light shades of yellow at the base.   The fragrance is particularly rich, with Tea rose overtones.   When established, it seems to flower continuously, especially if deadheaded.   Introduced by Barbier, France 1903 (20ft (6m). 
p118   Ramblers on swags and pillars:   Good choices are the Barbier Ramblers, creamy-yellow ‘Alberic Barbier’ and soft pink ‘Leontine Gervaise’
p119  Photo.  ‘Léontine Gervaise’  is seen here tumbling over a low wall to give a cottagey effect.   Wires are used to established the tumbling appearance when the rose is young.   Once established, it needs no work apart from deadheading and a little shaping in winter.

'Léontine Gervais'. Origin: France (Barbier) 1904. Height 12ft / 3.6m. Z: 5.
This vigorous rambler, of R. wichuraiana origins, has splendidly sumptuous flowers. Its buds are very ornamental, showing pink and apricot as the sepals part. The flowers, which open in June, are semi-double, 3in / 8cm across, pink with yellow undertones, fading to creamy white in the sun. The petals are rounded at the tips and slightly notched, giving a decorative character to the flower shape. They have an excellent sweet scent. Flowers are carried in lavish clusters at the tips of long stems. New shoots are a striking plum colour and the foliage is very distinguished, with shapely little toothed leaflets that have a lively shining surface. In small gardens, to keep it within bounds, it may be pruned hard immediately after flowering. This is not a rose for timid effects - its blowsy abundance should be flaunted. It is admirable trained round an arch or gate, or over a pergola where it will make a scented tunnel and where the flowers are seen to particularly good effect with the sun shining through them. It can, with care, be planted with other roses of very pale pink, such as ‘New Dawn’, or white with cream undertones, such as ‘Madame Alfred Carriere’.

'Léontine Gervais'. Barbier, France, 1903. Rosa wichuraiana x ‘Souvenir de Catherine Guillot’. In all respects very similar to ‘Francois Juranville’ except the colour, which inclines towards copper and orange. As ‘Paul Transon’ (q.v.) has a much longer flowering season, I prefer it. 25 feet.
