*Nymphaea odorata*<\/span><\/em>\u00a0subsp.\u00a0<\/span>*tuberosa*<\/span><\/em>\u00a0. \u00c9galement connu sous le nom de n\u00e9nuphar blanc d’Am\u00e9rique ou n\u00e9nuphar odorant, *tuberosa* appartient au\u00a0sous\u00a0<\/em><\/span>–<\/span><\/em>\u00a0genre *Nymphaea*\u00a0et\u00a0est une sous-esp\u00e8ce de l’ esp\u00e8ce sauvage\u00a0*Nymphaea<\/em>\u00a0odorata*. Son nom japonais est *N\u00e9nuphar am\u00e9ricain*. Lors de sa d\u00e9couverte, il fut initialement appel\u00e9 n\u00e9nuphar tub\u00e9reux, un nom original d\u00e9riv\u00e9 de son nom scientifique, *tuberosa*, car les nouvelles pousses (nouveaux rhizomes) qui se forment sur le rhizome ressemblent aux tubercules des n\u00e9nuphars tropicaux.\u00a0L’esp\u00e8ce *Nymphaea odorata*, y compris sa sous-esp\u00e8ce, est originaire du Canada et d’Am\u00e9rique centrale, et a \u00e9galement \u00e9t\u00e9 signal\u00e9e au Br\u00e9sil et en Guyane, en Am\u00e9rique du Sud. *Nymphaea tuberosa* est originaire du centre et de l’est des \u00c9tats-Unis, principalement du nord-est, mais est souvent confondue avec *Nymphaea odorata*.\u00a0Les caract\u00e9ristiques distinctives de cette esp\u00e8ce (outre celles de *Nymphaea odorata*) sont ses feuilles flottantes arrondies, les lignes rouges sur les p\u00e9tioles et la fa\u00e7on dont les nouveaux points de croissance se forment sur le rhizome. Cette\u00a0vari\u00e9t\u00e9 \u00e0 rhizome est de grande taille et se d\u00e9veloppe tr\u00e8s bien, \u00e0 l’instar de *Nymphaea odorata*. Elle constitue une vari\u00e9t\u00e9 horticole repr\u00e9sentative, de type *Nymphaea tuberosa*. Ainsi, selon l’\u00e9quilibre de la fertilisation, elle peut fleurir m\u00eame si le rhizome est court. Cependant, la vitesse de croissance du rhizome est extr\u00eamement rapide, ce qui n\u00e9cessitera \u00e0 terme de la cultiver jusqu’\u00e0 une taille importante. Dans un environnement domestique classique, sa culture conviendra aux personnes exp\u00e9riment\u00e9es en n\u00e9nuphars rustiques, mais elle mettra \u00e0 l’\u00e9preuve leur savoir-faire. Cette esp\u00e8ce \u00e9tait auparavant connue\u00a0sous les noms scientifiques suivants\u00a0:\u00a0*Castalia tuberosa*<\/em>\u00a0,\u00a0*Leuconymphaea tuberosa*<\/em>\u00a0,\u00a0*N. odorata*<\/em>\u00a0var. Les esp\u00e8ces *Nymphaea\u00a0maxima<\/em>\u00a0* et\u00a0*N. tuberosa* \u00e9taient longtemps consid\u00e9r\u00e9es comme appartenant \u00e0 la m\u00eame esp\u00e8ce, et en 1994, elles ont \u00e9t\u00e9 regroup\u00e9es sous le nom de\u00a0<\/em>*Nymphaea odorata*<\/em>\u00a0subsp.\u00a0*tuberosa*<\/em> .\u00a0<\/span><\/p>\n

Conseils de Plantation pour les nymphaea rustiques en g\u00e9n\u00e9ral<\/div>\n
\n
    \n
  • Le contenant :<\/strong> Utilisez une coupe d’au moins 15 \u00e0 20 litres.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
    \n
      \n
    • Le substrat :<\/strong> Bannissez les terreaux horticoles classiques qui polluent l’eau ; optez pour de la terre de jardin argileuse non calcaire .<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
      \n
        \n
      • La position :<\/strong> Installez le rhizome de mani\u00e8re oblique en laissant d\u00e9passer le bourgeon terminal \u00e0 la surface du sol, puis recouvrez la terre de graviers pour emp\u00eacher les poissons de creuser.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n

          \n
            \n
          • Nettoyage :<\/strong> Coupez r\u00e9guli\u00e8rement les feuilles jaunies et les fleurs fan\u00e9es au ras de l’eau pour garder une belle v\u00e9g\u00e9tation.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
            \n
              \n
            • Engrais :<\/strong> Apportez une dose d’engrais \u00e0 lib\u00e9ration lente sp\u00e9cial plantes aquatiques au pied de la plante chaque printemps pour stimuler la floraison.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
              \n
                \n
              • Hivernage :<\/strong> Les n\u00e9nuphars rustiques sont r\u00e9sistants au froid ; veillez simplement \u00e0 ce que le pot ne prenne pas dans la glace en profondeur (une immersion sup\u00e9rieure \u00e0 30 cm suffit \u00e0 les prot\u00e9ger).<\/span><\/li>\n<\/ul>\n<\/div>\n
                \n
                  \n
                • Division :<\/strong> Si la floraison diminue ou si le plant devient trop volumineux apr\u00e8s 3 ou 4 ans, sortez le pot au printemps pour diviser le rhizome<\/span><\/li>\n<\/ul>\n
