Nymphaea mexicana<\/span><\/em>\u00a0est \u00e9galement connu sous les noms de n\u00e9nuphar jaune, n\u00e9nuphar banane ou n\u00e9nuphar mexicain. Au Japon, il est appel\u00e9 n\u00e9nuphar jaune. C’est le seul n\u00e9nuphar semi-rustique et, bien qu’appartenant au m\u00eame\u00a0sous-genre\u00a0<\/span>Nymphaea que\u00a0<\/span><\/em>le n\u00e9nuphar rustique, il est la seule esp\u00e8ce poss\u00e9dant un segment appel\u00e9\u00a0<\/span><\/em>Xanthantha<\/span><\/em>\u00a0.<\/span><\/p>\n

Son nom scientifique lui a \u00e9t\u00e9 attribu\u00e9 pour la premi\u00e8re fois en 1832 par Joseph Gerhard Zuccarini, botaniste allemand et professeur \u00e0 l’Universit\u00e9 de Munich, \u00e9galement connu pour ses travaux sur la flore japonaise men\u00e9s en collaboration avec Philipp Franz von Siebold. On pense qu’il a \u00e9t\u00e9 collect\u00e9 pour la premi\u00e8re fois en 1827 au Mexique par Wilhelm Friedrich Karwinski von Karwin, un explorateur allemand r\u00e9put\u00e9 pour sa passion des plantes et ses activit\u00e9s de collecte.

\nen 1832 par Asa Gray, consid\u00e9r\u00e9 comme l’un des botanistes am\u00e9ricains les plus importants du XIXe si\u00e8cle, sous le nom de\u00a0<\/span>Nymphaea mexicana , s’est av\u00e9r\u00e9e \u00eatre\u00a0<\/span><\/em>Nymphaea elegans<\/span><\/em>\u00a0, un n\u00e9nuphar tropical appartenant au sous-genre Brachyceras.<\/span><\/p>\n

C\u00f4t\u00e9 culture, il s’agit d’une esp\u00e8ce rampante qui se d\u00e9veloppe par stolons (branches rampantes) au ras du sol. Bien qu’elle soit l’une des esp\u00e8ces les plus faciles \u00e0 cultiver du genre Nymphaea, elle est extr\u00eamement prolifique. Son rhizome est parfois compar\u00e9 \u00e0 celui d’un ananas, mais contrairement aux rhizomes typiques du sous-genre Nymphaea qui s’\u00e9tendent horizontalement, il pousse vers le bas ; il est donc pr\u00e9f\u00e9rable de la planter verticalement. Semi-rustique, elle survit facilement \u00e0 l’hiver en ext\u00e9rieur\u00a0 ; toutefois, la prudence est de mise dans les r\u00e9gions plus froides.<\/span>
\nSes fleurs sont jaunes, et c’est une esp\u00e8ce sauvage tr\u00e8s r\u00e9put\u00e9e, utilis\u00e9e comme parent pour la cr\u00e9ation de vari\u00e9t\u00e9s horticoles de n\u00e9nuphars r\u00e9sistants au froid, dans les tons jaunes et orang\u00e9s. Impossible de parler de n\u00e9nuphars jaunes sans mentionner Nymphaea Mexicana.<\/span><\/p>\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
