La Pontederia rotundifolia<\/strong> (commun\u00e9ment appel\u00e9e la pont\u00e9d\u00e9rie tropicale ou pont\u00e9d\u00e9rie \u00e0 feuilles rondes) est une plante aquatique vivace<\/strong>\u00a0originaire des zones mar\u00e9cageuses d’Am\u00e9rique du Sud et d’Am\u00e9rique centrale. Contrairement \u00e0 sa cousine plus courante (Pontederia cordata<\/em>), elle se caract\u00e9rise par un port tapissant unique et une moindre rusticit\u00e9 face au gel.<\/div>\n

  • Feuillage :<\/strong> Ses feuilles vertes et brillantes ont la particularit\u00e9 d’\u00eatre r\u00e9niformes \u00e0 cordiformes<\/strong> (en forme de rein ou de c\u0153ur arrondi). Elles sont port\u00e9es par de longs p\u00e9tioles reli\u00e9s \u00e0 des tiges tra\u00eenantes qui rampent \u00e0 la surface de l’eau, formant un tapis v\u00e9g\u00e9tal dense.<\/span>\n

  • Floraison :<\/strong> Durant l’\u00e9t\u00e9, la plante produit des inflorescences en \u00e9pis dress\u00e9s. Les fleurs affichent une corolle pubescente de couleur\u00a0bleu clair<\/strong>, agr\u00e9ment\u00e9e d’une tache jaune distinctive sur le t\u00e9pale sup\u00e9rieur. Les \u00e9couvillons floraux s’\u00e9l\u00e8vent jusqu’\u00e0 50 ou 60 cm au-dessus de l’eau.<\/span>\u00a0<\/li>\n
  • Syst\u00e8me racinaire :<\/strong> Ses racines forment un r\u00e9seau dense sous l’eau, offrant un excellent refuge naturel pour les alevins et la petite faune aquatique.<\/span>\u00a0<\/li>\n

    Conditions de culture et maintenance<\/div>\n
      \n
    • Exposition :<\/strong> Elle appr\u00e9cie une exposition en plein soleil<\/strong> pour garantir une belle floraison.<\/span><\/li>\n
    • Plantation :<\/strong> Sa profondeur id\u00e9ale d’installation se situe entre -10 cm et -40 cm<\/strong>. Elle peut s’enraciner dans un sol mar\u00e9cageux ou \u00eatre cultiv\u00e9e de mani\u00e8re partiellement flottante.<\/span>\u00a0<\/li>\n
    • <\/li>\n
    • Param\u00e8tres de l’eau :<\/strong> Elle s’\u00e9panouit dans une eau douce et plut\u00f4t acide \u00e0 neutre (pH entre 6,5 et 7,5). Dans un cadre tropical ou en aquarium, la temp\u00e9rature id\u00e9ale se situe entre 22\u00b0C et 27\u00b0C<\/strong>.<\/span>\u00a0<\/li>\n
    • Rusticit\u00e9 :<\/strong> C’est une plante sensible au gel<\/strong>. En Europe, ses bourgeons terminaux doivent \u00eatre prot\u00e9g\u00e9s du froid. Il est fortement conseill\u00e9 de la planter en pot afin de pouvoir la rentrer \u00e0 l’abri du gel durant l’hiver.<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
