Duc de Guiche est un autre Provins de forme exquise. Ses fleurs sont plus petites que celles de Charles de Mills mais très doubles et particulièrement séduisantes. La couleur est cramoisi suffusé de pourpre. .....Else Thykier, Skorrebrovejen, 3720 Aakirkeby, Danmark

Duc de Guiche (Gallica) Flowers of extra good shape, comparable with 'Belle de Crècy' and 'Mme. Hardy'. It is a sturdy plant, however, and a true gallica. Intense rosy-crimson heavily veined with violet-purple. Sometimes labelled 'Duc de Valmy'. Superlative quality. Recommended.
