Le <\/span>Nuphar nain<\/strong> (Nuphar pumila<\/em>), \u00e9galement appel\u00e9 petit n\u00e9nuphar jaune, est une plante aquatique vivace<\/strong> de la famille des Nymph\u00e9ac\u00e9es. Version miniature du n\u00e9nuphar jaune commun (Nuphar lutea<\/em>), il s’agit d’une esp\u00e8ce rare, prot\u00e9g\u00e9e et consid\u00e9r\u00e9e comme une relique glaciaire en Europe.\u00a0<\/div>\n

1. Description botanique<\/div>\n<\/div>\n
\n
    \n
  • Morphologie g\u00e9n\u00e9rale :<\/strong> C’est une plante compacte dont la hauteur oscille entre 30 et 60 cm. Ses racines rhizomateuses robustes s’ancrent au fond de l’eau, tandis que ses feuilles et ses fleurs flottent \u00e0 la surface.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
    \n
      \n
    • Les feuilles :<\/strong> Elles sont ovales en c\u0153ur, mesurent environ 5 \u00e0 10 cm de diam\u00e8tre et arborent une couleur vert moyen. Leurs p\u00e9tioles sont l\u00e9g\u00e8rement comprim\u00e9s au sommet.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
      \n
        \n
      • Les fleurs :<\/strong> De couleur jaune vif, elles ressemblent \u00e0 des boutons d’or ronds mesurant \u00e0 peine 2 \u00e0 3 cm de diam\u00e8tre. Elles sont port\u00e9es l\u00e9g\u00e8rement au-dessus de l’eau.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
        \n
          \n
        • Crit\u00e8re de distinction :<\/strong> Pour ne pas le confondre avec le grand n\u00e9nuphar jaune, on observe son disque stigmatique (au centre de la fleur) : celui du n\u00e9nuphar nain est profond\u00e9ment \u00e9chancr\u00e9 avec des bords lob\u00e9s \u00e0 lobes aigus.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n

            2. Habitat naturel et \u00e9cologie<\/div>\n<\/div>\n
            \n
              \n
            • Origine :<\/strong> Zone bor\u00e9ale et eurosib\u00e9rienne (Scandinavie, Sib\u00e9rie, Europe centrale).<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
              \n
                \n
              • Milieu :<\/strong> Il affectionne les eaux calmes, stagnantes, froides et plut\u00f4t pauvres en nutriments (oligotrophes) des lacs d’altitude et des \u00e9tangs.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
                \n
                  \n
                • En France :<\/strong> Devenu tr\u00e8s rare et menac\u00e9 par la d\u00e9t\u00e9rioration de la qualit\u00e9 des eaux, on ne le trouve plus que de fa\u00e7on tr\u00e8s localis\u00e9e dans le Massif central, les Vosges et le Jura. Son pr\u00e9l\u00e8vement dans la nature y est strictement interdit<\/strong>.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n

                    3. Culture et utilisation au jardin<\/div>\n<\/div>\n
                    \n
                      \n
                    • Id\u00e9al pour petits espaces :<\/strong> Contrairement aux grands n\u00e9nuphars, sa petite taille permet de le cultiver facilement dans un mini-bassin, un conteneur, une bassine ou une pot\u00e9e aquatique sur un balcon ou une terrasse.<\/span><\/li>\n<\/ul>\n<\/div>\n
                      \n
                        \n
                      • Profondeur de plantation :<\/strong> Il n\u00e9cessite peu de hauteur d’eau, sa profondeur id\u00e9ale d’immersion se situant entre 15 et 35 cm.<\/span><\/li>\n<\/ul>\n<\/div>\n
                        \n
                          \n
                        • Exposition :<\/strong> Lumineuse \u00e0 ensoleill\u00e9e.<\/span><\/li>\n<\/ul>\n<\/div>\n
                          \n
                            \n
                          • Substrat :<\/strong> Un sol aquatique pauvre. \u00c9vitez les terreaux trop riches qui favorisent la prolif\u00e9ration des algues.<\/span><\/li>\n<\/ul>\n<\/div>\n
                            \n
                              \n
                            • Entretien :<\/strong> C’est une plante rustique (qui r\u00e9siste bien au gel). Son feuillage est caduc, il dispara\u00eet en hiver pour r\u00e9appara\u00eetre au printemps.<\/span><\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
