Hydrocharis morsus-ranae<\/strong><\/em>, commun\u00e9ment appel\u00e9e grenouillette<\/strong>, mor\u00e8ne des grenouilles<\/strong> ou petit n\u00e9nuphar<\/strong>, est une petite plante aquatique vivace et flottante<\/strong> originaire d’Europe, d’Asie et d’Afrique du Nord. Elle appartient \u00e0 la famille des Hydrocharitaceae<\/em>.\u00a0<\/div>\n

\u00a0Description morphologique<\/div>\n
    \n
  • Les feuilles :<\/strong> Elles ressemblent \u00e0 des n\u00e9nuphars miniatures. Elles sont vertes, charnues, en forme de c\u0153ur ou d’\u00e9cuelle (2 \u00e0 4 cm de diam\u00e8tre) et forment un petit tapis \u00e0 la surface de l’eau.<\/span>\u00a0<\/li>\n
  • Les fleurs :<\/strong> Elles apparaissent en \u00e9t\u00e9 (juin \u00e0 ao\u00fbt). Elles sont petites, mesurent environ 1 \u00e0 2 cm, poss\u00e8dent trois p\u00e9tales blancs<\/strong> d\u00e9licats et un c\u0153ur jaune.<\/span>\u00a0<\/li>\n
  • Les racines :<\/strong> Ses racines sont a\u00e9riennes et suspendues dans l’eau. La plante ne s’enracine pas dans le sol<\/strong>, ce qui la rend tr\u00e8s facile \u00e0 manipuler et \u00e0 contr\u00f4ler.<\/span>\u00a0<\/li>\n

    \u00a0Cycle de vie et reproduction<\/div>\n
    La grenouillette a un mode de reproduction fascinant adapt\u00e9 aux saisons :<\/div>\n
      \n
    • En \u00e9t\u00e9 :<\/strong> Elle se propage tr\u00e8s rapidement \u00e0 la surface de l’eau gr\u00e2ce \u00e0 des tiges horizontales appel\u00e9es stolons<\/strong>.<\/span><\/li>\n
    • En automne :<\/strong> Elle produit des bourgeons sp\u00e9ciaux (appel\u00e9s hibernacles<\/strong>). La plante m\u00e8re meurt, et ces bourgeons tombent au fond de l’eau pour passer l’hiver \u00e0 l’abri du gel.<\/span><\/li>\n
    • Au printemps :<\/strong> Avec le r\u00e9chauffement de l’eau, les bourgeons remontent \u00e0 la surface et se d\u00e9veloppent pour former de nouveaux plants.<\/span>\u00a0<\/li>\n

      <\/ul>\n

      <\/div>\n
      \u00a0Habitat et conditions de culture<\/div>\n
        \n
      • Type d’eau :<\/strong> Elle pr\u00e9f\u00e8re les eaux calmes, stagnantes ou \u00e0 faible courant<\/strong> (mares, \u00e9tangs, bras morts de rivi\u00e8res). Elle redoute les eaux trop calcaires.<\/span>\u00a0<\/li>\n
      • Exposition :<\/strong> Plein soleil \u00e0 mi-ombre.<\/span>\u00a0<\/li>\n
      • Int\u00e9r\u00eat \u00e9cologique :<\/strong> C’est une excellente plante oxyg\u00e9nante<\/strong>. En couvrant la surface, elle limite la prolif\u00e9ration des algues et offre un parfait refuge pour la faune aquatique, notamment les grenouilles et les t\u00eatards.<\/span>\u00a0<\/li>\n

        <\/ul>\n

        <\/div>\n

        <\/span><\/p>\n

        Note environnementale :<\/strong> Si elle est prot\u00e9g\u00e9e ou menac\u00e9e dans certaines r\u00e9gions d’Europe en raison de la disparition de ses habitats, elle a \u00e9t\u00e9 introduite en Am\u00e9rique du Nord o\u00f9 elle est devenue une esp\u00e8ce exotique envahissante<\/strong> \u00e0 surveiller de pr\u00e8s.\u00a0<\/div>\n
