Le Caltha palustris var. alba<\/strong> (commun\u00e9ment appel\u00e9 Populage des marais blanc<\/strong> ou Souci d’eau blanc<\/strong>) est une plante vivace semi-aquatique tr\u00e8s appr\u00e9ci\u00e9e pour illuminer les bordures de bassins d\u00e8s le d\u00e9but du printemps. Contrairement \u00e0 l’esp\u00e8ce type qui arbore des fleurs jaune d’or, cette vari\u00e9t\u00e9 se distingue par une floraison d’un blanc pur et lumineux<\/p>\n

Caract\u00e9ristiques morphologiques<\/div>\n
    \n
  • Les fleurs :<\/strong> Elle produit de charmantes fleurs en forme de coupes, compos\u00e9es de t\u00e9pales blanc pur<\/strong> qui entourent un c\u0153ur contrast\u00e9 de nombreuses \u00e9tamines jaune vif<\/strong>. La floraison principale a lieu au printemps (de mars \u00e0 mai), avec parfois une discr\u00e8te remont\u00e9e \u00e0 l’automne.<\/span>\u00a0<\/li>\n
  • Le feuillage :<\/strong> Ses feuilles sont caduques, arrondies \u00e0 r\u00e9niformes (en forme de rein)<\/strong>, d’un vert brillant et verniss\u00e9. Elles forment une touffe dense et compacte.<\/span>\u00a0<\/li>\n
  • Dimensions :<\/strong> C’est une plante de petite taille, atteignant environ 20 \u00e0 30 cm de hauteur<\/strong> pour autant d’\u00e9talement. Elle est beaucoup moins envahissante que d’autres plantes de bassin.<\/span>\u00a0<\/li>\n

    \u00a0Conditions de culture et plantation<\/div>\n
      \n
    • Exposition :<\/strong> Elle s’\u00e9panouit pleinement au soleil<\/strong> ou \u00e0 la mi-ombre. Une bonne luminosit\u00e9 garantit une floraison g\u00e9n\u00e9reuse.<\/span><\/li>\n
    • Type de sol \/ Milieu :<\/strong> C’est une plante de zone humide par excellence. Elle se pla\u00eet les pieds dans l’eau. On l’installe g\u00e9n\u00e9ralement en bordure immerg\u00e9e, \u00e0 une profondeur d’eau comprise entre 0 et -5 cm<\/strong> maximum (le niveau de l’eau au-dessus du collet). Elle peut aussi pousser en pleine terre si le sol reste constamment d\u00e9tremp\u00e9 ou mar\u00e9cageux.<\/span><\/li>\n
    • Rusticit\u00e9 :<\/strong> Tr\u00e8s robuste, elle r\u00e9siste \u00e0 des temp\u00e9ratures hivernales descendant jusqu’\u00e0 -25 \u00b0C<\/strong>.<\/span>\u00a0<\/li>\n

      <\/div>\n
      \u00a0Utilisation au jardin<\/div>\n
      Le Souci d’eau blanc est id\u00e9al pour am\u00e9nager les berges des petits bassins<\/strong>, les ruisseaux de jardin, les zones de lagunage ou m\u00eame dans des contenants \u00e9tanches (comme des bassines en zinc d\u00e9coratives) plac\u00e9s sur une terrasse humide. C’est \u00e9galement une excellente plante mellif\u00e8re qui attire les premiers insectes pollinisateurs \u00e0 la sortie de l’hiver.\u00a0<\/div>\n
      Note : En fin d’\u00e9t\u00e9, la plante peut entrer en dormance pr\u00e9coce ; son feuillage jaunit et fane naturellement pour r\u00e9appara\u00eetre vigoureusement le printemps suivant.<\/em><\/div>\n
