Culture<\/h4>\n

Il est facile \u00e0 cultiver dans un sol moyen, l\u00e9g\u00e8rement acide, sec \u00e0 moyennement humide, bien drain\u00e9, en plein soleil ou \u00e0 l’ombre partielle. Pr\u00e9f\u00e8re le plein soleil dans la partie nord de son aire de culture, mais appr\u00e9cie un peu d’ombre l’apr\u00e8s-midi dans la r\u00e9gion de Saint-Louis. Tol\u00e8re une large gamme de conditions de sol. Tailler au besoin imm\u00e9diatement apr\u00e8s la floraison et au plus tard \u00e0 la mi-ao\u00fbt. Les plantes peuvent \u00eatre coup\u00e9es pr\u00e8s du sol en hiver pour rajeunir. Les plantes ont souvent du mal \u00e0 supporter les climats estivaux chauds et humides du Sud profond, dans les zones 8-9 de l’USDA.<\/p>\n<\/div>\n

Caract\u00e9ristiques remarquables<\/h4>\n

Physocarpus opulifolius<\/em>, commun\u00e9ment appel\u00e9 ninebark, est un arbuste \u00e0 feuilles caduques, \u00e9rig\u00e9, \u00e9tal\u00e9, quelque peu grossier, originaire du Missouri et \u00e9troitement li\u00e9 au genre Spiraea<\/em>. Dans le Missouri, elle se rencontre g\u00e9n\u00e9ralement le long des cours d’eau, des berges rocheuses, des bancs de gravier et dans les fourr\u00e9s humides, en particulier dans les comt\u00e9s situ\u00e9s au sud de la rivi\u00e8re Missouri (Steyermark). Pousse de 5 \u00e0 9 pieds de haut (plus rarement jusqu’\u00e0 10 pieds). Remarqu\u00e9 pour son \u00e9corce exfoliante (sur les branches matures) qui se d\u00e9tache en bandes pour r\u00e9v\u00e9ler plusieurs couches d’\u00e9corce interne rouge\u00e2tre \u00e0 brun clair (d’o\u00f9 le nom commun d’\u00e9corce \u00e0 neuf feuilles). L’\u00e9corce est int\u00e9ressante en hiver, mais elle est g\u00e9n\u00e9ralement cach\u00e9e par le feuillage pendant la saison de croissance. Petites fleurs roses ou blanches \u00e0 cinq p\u00e9tales apparaissant en grappes denses, plates, arrondies, de 1 \u00e0 2 pouces de diam\u00e8tre, semblables \u00e0 des spirales (corymbes) \u00e0 la fin du printemps. Les fleurs laissent place \u00e0 des grappes tombantes de fruits rouge\u00e2tres (capsules de graines gonfl\u00e9es). Les feuilles ovales \u00e0 arrondies, g\u00e9n\u00e9ralement \u00e0 3 ou 5 lobes (jusqu’\u00e0 4″ de long) sont d’un vert terne en \u00e9t\u00e9 et passent \u00e0 un jaune discret en automne.<\/p>\n

Le nom du genre vient du grec physa<\/em> qui signifie vessie et karpos<\/em> qui signifie fruit, en r\u00e9f\u00e9rence aux fruits secs gonfl\u00e9s de la plante.<\/p>\n

L’\u00e9pith\u00e8te sp\u00e9cifique fait r\u00e9f\u00e9rence aux feuilles qui ressemblent \u00e0 celles de Viburnum opulus<\/em>.<\/p>\n

Le nom commun de l’alisier est une r\u00e9f\u00e9rence \u00e0 son \u00e9corce exfoliante et attrayante pour l’ornement.<\/p>\n<\/div>\n

\n

Probl\u00e8mes<\/h4>\n

Le feu bact\u00e9rien, l’o\u00efdium et les taches foliaires peuvent appara\u00eetre.<\/p>\n<\/div>\n

\n

Utilisations<\/h4>\n

En masse dans les bordures d’arbustes. Efficace comme haie, \u00e9cran ou pour le contr\u00f4le de l’\u00e9rosion sur les berges. Jardin de plantes indig\u00e8nes. Capable de pousser dans des conditions difficiles.<\/p>\n
