‘Blanc Double de Coubert’, Rugosahybride, Cochet-Cochet, France, 1892
By its very good hardiness this rose is probably a filled form of Rosa rugosa ‘Alba’. ‘Blanc Double the Coubert’ is a most desirable hybrid with typical Rugosa foliage. She has large, snowy white, fairly double flowers all season. The flowers are noticable for their fragrance. Because of the double flowers ‘Blanc Double de Coubert’ rarely forms hips, but when she does, they are orange-scarlet. The foliage is dark, leathery and wrinkled and she usually grows into a medium sized shrub. The leaves, inflorescence and fine spines of this shrub are so similar to Rosa rugosa that the assertion of the breeder that ‘Mlle. de Sombreuil’ was the pollen parent has to be questioned, although the plant grows much more open than the wild Rosa rugosa.
Hardiness: to average -35 °C
