 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’.

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.

 A very close relative of R. wichuraiana, R. luciae appears to have been used to produce a small group, of which ‘Alberic Barbier’ and ‘Albertine’ are the most familiar and which can best be described as coming halfway between ramblers and climbers.   They flower earlier than the other ramblers, their flowers are bigger and in smaller clusters, their canes are stiffer,  and they do not just produce new growth from ground level, which means their pruning has to be different.   Yet by ancestry they are ramblers, and they are not recurrent.   The French firm of Barbier was instrumental in breeding many of the best ramblers round about the turn of the century and they rapidly became enormously popular.

 .....if the two species are compared, the correct botanical description of R. luciae must be given first priority (over R. wichuraiana.  Yet this has not been the case even though the  Americans regard the two species as one.   It is only known for sure that Barbier used R. luciae in his breeding program.

La Roseraie d’Orléans (garden) .......and no less than 530 climbers and ramblers.   The latter are wonderfully displayed on a large pergola, on trellis-work screens and on pylons, and are of particular interest because the district around Orléans was the birthplace of so many of them.   Among other raisers working in the field, between 1900 and 1914 René Barbier used R. wichuraiana and its close relative R. luciae, which had been introduced from Japan, in the breeding of ‘Alberic Barbier’,  Francois Juranville’,  Alexandre Girault’,  ‘Leontine Gervaise’,  ‘Albertine’ and ‘Primavère’,  all of which can still be found in the garden, amongst a wealth of others.
