White cottage rose, German Weisse Rose; French rose blanche; Italian rosa bianca; Russian roza belaja kazanlykskaja; Chinese bai qiang wei; Hindi gulab, swet; Korean hinkkothyangjangmi.
Area of origin unknown.
Cultivated in S France, Bularia (here the cultivar 'Semiplena'), Turkey, Crimea, India and North Korea for the use of flowers.
The produced oil is less precious than that of R. damascena, but the plants are more resistant to weather calamities. In India flowers and fruits are drugs. In Java the young tips of the shoots are eaten as a vegetable ("lablab") together with rice.
Cultivation in Europe possibly since the Roman era.

Rosa x alba /Rosa x alba L. /’Rose blanche’, ‘Rose blanche d’York’ /’Rose d’York’ = Section gallicanae. Parent: Peut-être Rosa coriifolia var froebelii (ou Rosa canina ou une espèce proche) x Rosa x damascena (ou encore Rosa corymbifera x Rosa gallica?). Existe depuis les temps anciens… Feuilles = 5 folioles, elliptiques larges à ovales ou oblongues-ovales, longueur 2 à 6cm, bords à dents simples... aiguillons recourbés et inégaux, parfois aussi des cils. Le feuillage, velu sur les revers, est le plus souvent grisâtre ou glaucescent. Les fleurs, toujours odorantes, s’épanouissent en juin, et ne remontent pas. Les fruits sont ronds, rouges et lisses. Tous les hybrides de ce groupe ont une bonne rusticité.

Important among the old garden Roses is R. alba. Though it is allowed to bear a botanical name, it is not thought to be a species, but is considered a cross between canina and gallica. This capital Rose is often seen in cottage gardens, where it is a great favourite. The double white form is the most frequent, but the delicate pink Maiden's Blush is a better flower. Lovelier still is the less double Celeste, a Rose of wonderful beauty when the bud is half opened. When once known the albas may be recognised, even out of flower, by the bluish colouring and general look of the very broad leafleted leaves. The blue colouring is accentuated in Celeste, and is a charming accompaniment to the rosy tinting of the heart of the opening flower. The albas, as well as others of the garden Roses, make admirable standards, their hardiness and strong constitution enabling them to be grown into quite large-headed bushes. It is no uncommon thing to see standards with heads a yard through in the gardens of cottagers, who also grow some of the Ayrshires in this way.

Le Rosa alba L., autre hybride de R. gallica et de R. canina, est au contraire [de R. turbinata] beacoup plus voisin de ce dernier...Ce n'est pas l'odeur de Rose véritable, c'est le parfum faible et presque caractèristique des R. canina odorants.
