Heteranthera reniformis<\/strong>, commun\u00e9ment appel\u00e9e l’h\u00e9t\u00e9ranth\u00e8re r\u00e9niforme<\/strong>, est une plante aquatique de la famille des Pontederiaea<\/mark>. Originaire d’Am\u00e9rique<\/strong> (du Nord et du Sud), elle se caract\u00e9rise par ses petites feuilles luisantes en forme de c\u0153ur ou de rein (r\u00e9niformes<\/em>) et ses discr\u00e8tes fleurs blanches \u00e0 bleu p\u00e2le.\u00a0<\/div>\n

Caract\u00e9ristiques principales<\/div>\n
    \n
  • Morphologie :<\/strong> C’est une plante amphibie rampante qui s’enracine au niveau des n\u0153uds. Ses tiges immerg\u00e9es sont charnues, tandis que ses feuilles vert tendre se d\u00e9veloppent g\u00e9n\u00e9ralement en surface ou \u00e9merg\u00e9es.<\/span><\/li>\n
  • Dimensions :<\/strong> Sa hauteur varie de 10 \u00e0 30 cm<\/strong> (parfois jusqu’\u00e0 50 cm).<\/span><\/li>\n
  • Floraison :<\/strong> Elle produit de petites grappes de 2 \u00e0 10 fleurs<\/strong> qui s’\u00e9panouissent entre ao\u00fbt et septembre.<\/span><\/li>\n

    Conditions de culture & Utilisation<\/div>\n
      \n
    • Exposition :<\/strong> Elle demande un \u00e9clairage moyen \u00e0 intense<\/strong> et appr\u00e9cie particuli\u00e8rement le plein soleil.<\/span><\/li>\n
    • Param\u00e8tres de l’eau :<\/strong> Elle tol\u00e8re des temp\u00e9ratures allant de 18 \u00e0 30 \u00b0C<\/strong> et un pH de 6,0 \u00e0 7,5<\/strong>.<\/span><\/li>\n
    • Milieu :<\/strong> Bien qu’elle puisse pousser en aquarium, ses exigences lumineuses \u00e9lev\u00e9es et sa tendance \u00e0 \u00e9merger la rendent bien plus adapt\u00e9e pour les paludariums<\/strong> ou les bassins de jardin<\/strong> en \u00e9t\u00e9 (sur les berges humides entre 0 et -20 cm de profondeur). Attention : elle craint le gel et doit \u00eatre rentr\u00e9e en hiver dans les r\u00e9gions froides.<\/em><\/span><\/li>\n

      Statut \u00e9cologique (Esp\u00e8ce exotique envahissante)<\/div>\n
      Introduite en France \u00e0 la fin des ann\u00e9es 1980 (notamment en Camargue), l’h\u00e9t\u00e9ranth\u00e8re r\u00e9niforme est une plante \u00e0 croissance rapide et vigoureuse<\/strong>. Elle se propage facilement par stolons et graines, ce qui lui permet de coloniser rapidement les zones humides et les rizi\u00e8res, o\u00f9 elle est parfois consid\u00e9r\u00e9e comme une mauvaise herbe tenace.<\/div>\n","protected":false},"excerpt":{"rendered":"
