L’<\/span>Iris de Louisiane<\/strong> n’est pas une esp\u00e8ce unique, mais un groupe horticole compos\u00e9 de cinq esp\u00e8ces sauvages originaires des zones humides du sud-est des \u00c9tats-Unis<\/mark>, parmi lesquelles l’Iris nelsonii<\/strong><\/em> (souvent appel\u00e9 \u00ab Abbeville Red<\/strong> \u00bb). D\u00e9couvert \u00e0 la fin des ann\u00e9es 1930 et officiellement class\u00e9 en 1966, l’Iris nelsonii<\/em> est la plus rare de ces esp\u00e8ces.\u00a0<\/div>\n

Caract\u00e9ristiques principales de l’Iris nelsonii<\/div>\n<\/div>\n
\n
    \n
  • Origine unique :<\/strong> Il s’agit d’une esp\u00e8ce end\u00e9mique<\/strong> d’un seul mar\u00e9cage de cypr\u00e8s (le Abbeville swamp<\/em>) situ\u00e9 dans la paroisse de Vermilion, en Louisiane.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
    \n
      \n
    • Origine hybride naturelle :<\/strong> Des \u00e9tudes g\u00e9n\u00e9tiques ont montr\u00e9 qu’il est issu d’une hybridation naturelle stable entre trois autres esp\u00e8ces d’iris (Iris fulva<\/em>, Iris hexagona<\/em> et Iris brevicaulis<\/em>).<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
      \n
        \n
      • Taille impressionnante :<\/strong> Surnomm\u00e9 \u00ab Super Fulva \u00bb, il est beaucoup plus grand que l’Iris fulva<\/em>. Ses tiges robustes s’\u00e9l\u00e8vent g\u00e9n\u00e9ralement \u00e0 1,20 m<\/strong><\/span><\/li>\n<\/ul>\n<\/div>\n

          \u00a0Description morphologique<\/div>\n<\/div>\n
          \n
            \n
          • Les Fleurs :<\/strong> Elles mesurent environ 5 \u00e0 12 cm de diam\u00e8tre et se distinguent par leur port l\u00e9g\u00e8rement retombant. Sa couleur signature est un rouge brique vibrant, rouge violac\u00e9 ou cuivre<\/strong> tr\u00e8s recherch\u00e9, bien que des variations de jaune ou de brun-violet existent en milieu naturel.<\/span><\/li>\n<\/ul>\n<\/div>\n
            \n
              \n
            • Le Feuillage :<\/strong> Les feuilles sont vertes, lisses, en forme de glaive ou d’\u00e9p\u00e9e (ensiformes). Elles forment de grandes touffes denses.<\/span><\/li>\n<\/ul>\n<\/div>\n
              \n
                \n
              • Floraison :<\/strong> Elle a lieu au printemps, principalement au cours du mois de mai et juin<\/strong> (ou d\u00e8s avril dans son habitat d’origine).<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n

                  \u00a0Conditions de culture et entretien<\/div>\n<\/div>\n
                  \n
                  L’Iris nelsonii<\/em> et les hybrides d’Iris de Louisiane sont des plantes vigoureuses et faciles \u00e0 vivre si leurs besoins en eau sont respect\u00e9s :\u00a0<\/div>\n<\/div>\n
                  \n
                    \n
                  • Exposition :<\/strong> Plein soleil<\/strong> \u00e0 mi-ombre pour garantir une floraison g\u00e9n\u00e9reuse.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
                    \n
                      \n
                    • Nature du sol :<\/strong> Riche en mati\u00e8res organiques, acide \u00e0 neutre, et surtout constamment humide<\/strong>.<\/span><\/li>\n<\/ul>\n<\/div>\n
                      \n
                        \n
                      • Plantation aquatique :<\/strong> C’est une excellente plante de rive. Il s’\u00e9panouit les pieds dans l’eau, supportant une immersion permanente sous 5 cm d’eau maximum<\/strong>.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
                        \n
                          \n
                        • Rusticit\u00e9 :<\/strong> Malgr\u00e9 ses origines du Sud, il est tr\u00e8s rustique et supporte des gels allant jusqu’\u00e0 -10\u00b0C \u00e0 -15\u00b0C<\/strong> selon les vari\u00e9t\u00e9s.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
                          \n
                            \n
                          • Cycle de croissance :<\/strong> Il entre en repos (semi-dormance) durant les fortes chaleurs de l’\u00e9t\u00e9 o\u00f9 son feuillage peut jaunir. C’est le moment id\u00e9al pour diviser ses rhizomes. Sa croissance reprend activement d\u00e8s l’automne.<\/span><\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
