‘Agathe’: Les rosiers de Provins. On le considère généralement comme un hybride issu de Rosa gallica et Rosa damascena. Description… NB: L’appellation de ‘Agathe’ peut être une source de confusion, sachant qu’il existe tout un groupe de roses désignées sous ce nom. Elles présentent en général des fleurs petites, très doubles, les pétales de la périphérie étant inclinés vers le réceptable et ceux du centre dressés et concaves. Leurs coloris varient du rose pâle au pourpre et leurs feuilles sont semblables à celui de Rosa gallica.
