‘Blanc Double de Coubert’: Hybride de Rugosa… description… Il ressemble si fort à Rosa rugosa par son feuillage, son inflorescence et ses fins aiguillons, qu’on a mis en doute l’affirmation de son obtenteur selon laquelle ‘Sombreuil’ serait le parent pollinisateur, encore que son port soit plus ouvert que celui de Rosa rugosa. Coubert était le village de l’obtenteur. Cochet-Cochet, France, 1892. RHS Award of Garden Merit, 1993.
