La Sagittaria montevidensis<\/em>, commun\u00e9ment appel\u00e9e Sagittaire de Montevideo ou Fl\u00e8che d’eau d’Argentine<\/strong>, est une plante aquatique vivace et robuste appartenant \u00e0 la famille des Alismataceae. Originaire des zones humides d’Am\u00e9rique du Sud (notamment de la r\u00e9gion de Montevideo en Uruguay), elle est tr\u00e8s appr\u00e9ci\u00e9e dans les bassins d’ornement pour son graphisme et sa floraison bicolore unique.\u00a0<\/div>\n

  • Le feuillage :<\/strong> La plante doit son nom de \u00ab\u00a0Sagittaire\u00a0\u00bb (du latin sagitta<\/em>, la fl\u00e8che) \u00e0 la forme de ses feuilles \u00e9merg\u00e9es. Port\u00e9es par de longs p\u00e9tioles spongieux et charnus, les feuilles adultes sont grandes, glabres, vert clair, et adoptent une forme de pointe de fl\u00e8che ou de hallebarde<\/strong> tr\u00e8s marqu\u00e9e. Les jeunes feuilles immerg\u00e9es, quant \u00e0 elles, ressemblent plut\u00f4t \u00e0 de fins rubans.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n

      \n
    • Les fleurs :<\/strong> C\u2019est sa principale distinction esth\u00e9tique. Sa floraison, qui s’\u00e9tend de juin \u00e0 septembre<\/strong>, se compose de grappes dress\u00e9es portant des fleurs \u00e0 trois p\u00e9tales. Ces p\u00e9tales sont d’un blanc pur, orn\u00e9s \u00e0 leur base d’une tache (macule) rouge pourpre ou bordeaux tr\u00e8s contrast\u00e9e<\/strong>, entourant un c\u0153ur jaune.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
      \n
        \n
      • La taille :<\/strong> Elle forme une touffe dress\u00e9e qui s’\u00e9l\u00e8ve g\u00e9n\u00e9ralement entre 50 et 100 cm<\/strong> au-dessus de la surface de l’eau.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n

          • Exposition :<\/strong> Elle a besoin d’une exposition en plein soleil<\/strong> pour fleurir g\u00e9n\u00e9reusement.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
            \n
              \n
            • Plantation :<\/strong> C’est une plante de berge ou de faible profondeur. On l’installe id\u00e9alement sous 5 \u00e0 30 cm d’eau<\/strong> (jusqu’\u00e0 50 cm maximum) dans un sol riche et vaseux.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
              \n
                \n
              • Rusticit\u00e9 :<\/strong> Elle est semi-tropicale et frileuse<\/strong>. Dans les r\u00e9gions aux hivers rudes (nord de l’Europe), elle est souvent cultiv\u00e9e comme une plante annuelle car elle g\u00e8le facilement. Cependant, sa souche peut survivre si elle est immerg\u00e9e profond\u00e9ment en dessous de la zone de gel (au moins 30 cm d’eau) ou dans le sud de la France. Elle se propage et se ress\u00e8me \u00e9galement tr\u00e8s bien d’une ann\u00e9e sur l’autre.<\/span><\/li>\n
