Ses feuilles sont moins \u00e9troites que celles d’Epilobium dodonaei.<\/p>\n\n\n\n

Plante rhizomateuse formant des colonies. L’architecture est dite en Bell.<\/p>\n\n\n\n

Origine, distribution et taxonomie:<\/strong><\/h2>\n\n\n\n

Cet \u00e9pilobe a une tr\u00e8s large r\u00e9partition: circumbor\u00e9ale. Sachant que les plus petites cytologies<\/a> sont europ\u00e9ennes, et des r\u00e9gions parmi les plus froides.<\/p>\n\n\n\n

Il peut \u00eatre reconnu la sous-esp\u00e8ce circumvagum concernant les plantes d’Asie (hexaplo\u00efdes), et d’Am\u00e9rique (t\u00e9traplo\u00efdes)<\/p>\n\n\n\n

Ecologie<\/strong><\/h2>\n\n\n\n

L’\u00e9cologie de cette plante est amusante. En principe, les \u00e9pilobes sont plus ou moins inf\u00e9od\u00e9s aux zones humides. Ce n’est pas le caract\u00e8re qui va le mieux d\u00e9noter l’\u00e9cologie de cette esp\u00e8ce.<\/p>\n\n\n\n

C’est un plante de coupes foresti\u00e8res, coupes plut\u00f4t \u00e9nergiques. On la trouve donc parfois plut\u00f4t dans les ourlets internes — du c\u00f4t\u00e9 boisement. Typiquement, il peut arriver que le sol originel, avant la coupe, soit assez sec, voir un peu pauvre (la trophie<\/a> remonte avec l’\u00e9clairement due \u00e0 la coupe foresti\u00e8re, et moins d’eau se trouve mobilis\u00e9e par les arbres disparus). Ce qui est troublant; Or, c’est bien quelque chose qu’elle recherche. Le trouble. Elle est pionni\u00e8re. C’est une vivace. Sa situation pr\u00e9f\u00e9rentielle est \u00e0 la fois d’ourlets<\/a> (jusqu’aux sous bois, parfois) et de friches<\/a>: elle pr\u00e9f\u00e8re les situations rud\u00e9rales<\/a>. Ouverture des boisements sur sols frais (non sp\u00e9cialement tr\u00e8s humides, ni aussi secs que pr\u00e9c\u00e9demment), mais se trouve aussi en situations rivulaires.<\/p>\n\n\n\n

Les photos de cette fiche sont prises l\u00e0 o\u00f9 un immeuble a pr\u00e9c\u00e9demment \u00e9t\u00e9 abattu. Franchement, ces plantes sont \u00e0 peu de choses pr\u00e8s sur un reste de dalle de ciment.<\/p>\n\n\n\n

Plante des coupes foresti\u00e8res pionni\u00e8res et (ronciers de clairi\u00e8res) m\u00e9dio-europ\u00e9ennes, m\u00e9sohydriques \u00e0 m\u00e9sohygrophiles de l’Epilobietea angustifolii T\u00fcxen & Preising in T\u00fcxen 1950<\/p>\n\n\n\n

Cette plante est mellif\u00e8re.<\/p>\n\n\n\n
