Voici un rosier\u00a0botanique bien original. Il est originaire d\u2019Am\u00e9rique du Nord comme le tr\u00e8s beau Rosa foliolosa et pousse l\u00e0-bas dans les marais ou sur les berges des lacs.<\/p>\n

Sa v\u00e9g\u00e9tation est tr\u00e8s drageonnante et il \u00e9met de belles pousses rouge\u00e2tres aux aiguillons rares mais bien ac\u00e9r\u00e9s. La floraison est tr\u00e8s int\u00e9ressante puisqu\u2019elle survient en juillet \u2013ao\u00fbt sur une longue p\u00e9riode\u00a0; de jolies \u00e9glantines d\u2019un rose soutenu sont suivies de petits cynorrhodons rouges. Ce rosier promet bien des utilisations notamment son\u00a0implantation dans des zones humides et fragiles\u00a0o\u00f9 l\u2019urgence est de limiter l\u2019\u00e9rosion li\u00e9e \u00e0 l\u2019eau.<\/p>\n

D’un vert fonc\u00e9 brillant en \u00e9t\u00e9, le feuillage offre un spectacle automnal flamboyant en prenant des teintes rouge vineux \u00e0 pourpre<\/strong> avant de tomber.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
