Le jonc commun<\/strong> est une plante herbac\u00e9e vivace monocotyl\u00e9done appartenant \u00e0 la famille des Juncaceae<\/strong>. Tr\u00e8s r\u00e9pandu dans les zones humides de l’h\u00e9misph\u00e8re Nord, il se reconna\u00eet facilement \u00e0 ses touffes denses et h\u00e9riss\u00e9es d’un vert \u00e9clatant, ainsi qu’\u00e0 son port graphique tr\u00e8s sculptural.\u00a0<\/div>\n<\/div>\n

\u00a0Description botanique<\/div>\n<\/div>\n
\n
    \n
  • Tiges :<\/strong> Elles mesurent entre 40 cm et 1,20 m\u00e8tre de haut<\/strong>. Elles sont cylindriques, lisses \u00e0 l’\u00e9tat frais (finement stri\u00e9es une fois s\u00e8ches), sans n\u0153uds, et rigides. L’int\u00e9rieur est rempli d’une moelle blanche continue et spongieuse.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
    \n
      \n
    • Feuilles :<\/strong> Les feuilles sont presque inexistantes. Elles sont r\u00e9duites \u00e0 de simples gaines basales rouss\u00e2tres \u00e0 brunes<\/strong> qui entourent la base des tiges.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
      \n
        \n
      • Inflorescence :<\/strong> Contrairement aux gramin\u00e9es classiques, la floraison semble sortir du c\u00f4t\u00e9 de la tige (panicule lat\u00e9rale). Elle forme une grappe l\u00e2che, diffuse et ramifi\u00e9e de couleur brun verd\u00e2tre \u00e0 beige<\/strong>.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
        \n
          \n
        • Fleurs :<\/strong> Petites (environ 2 mm), discr\u00e8tes et de structure similaire \u00e0 celle d’un petit lis, compos\u00e9es de 6 pi\u00e8ces de p\u00e9rianthe pointues et de 3 \u00e9tamines.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
          \n
            \n
          • Fruits :<\/strong> De petites capsules de forme obovale contenant de nombreuses graines microscopiques dispers\u00e9es par le vent ou l’eau.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
            \n
              \n
            • Racines :<\/strong> Il poss\u00e8de un syst\u00e8me racinaire compos\u00e9 de rhizomes tra\u00e7ants et horizontaux<\/strong>, ce qui lui permet de stabiliser les sols et de s’\u00e9tendre rapidement.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n

                \u00c9cologie et Habitat<\/div>\n<\/div>\n
                \n
                Le jonc commun est une plante semi-aquatique tr\u00e8s rustique (r\u00e9sistant jusqu’\u00e0 -29 \u00b0C).\u00a0<\/div>\n<\/div>\n
                \n
                  \n
                • Milieux :<\/strong> On le trouve dans les foss\u00e9s, les prairies humides, les mar\u00e9cages, les tourbi\u00e8res et sur les berges des cours d’eau ou des \u00e9tangs.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n
                  \n
                    \n
                  • Indicateur :<\/strong> Sa pr\u00e9sence massive indique souvent un sol gorg\u00e9 d’eau (hydromorphe), compact ou sujet \u00e0 de fortes variations de nappes phr\u00e9atiques.<\/span>\u00a0<\/li>\n<\/ul>\n<\/div>\n

                      \n
                        \n
                      • Phyto\u00e9puration :<\/strong> Il est tr\u00e8s utilis\u00e9 dans les bassins de lagunage et les filtres plant\u00e9s car ses racines absorbent efficacement les polluants, les nitrates et les phosphates de l’eau.<\/span><\/li>\n<\/ul>\n<\/div>\n
                        \n
                          \n
                        • Vannerie et artisanat :<\/strong> Historiquement, ses tiges s\u00e9ch\u00e9es servaient \u00e0 fabriquer des liens, \u00e0 rempailler des chaises (vannerie de jonc) ou \u00e0 confectionner des nattes.<\/span><\/li>\n<\/ul>\n<\/div>\n
                          \n
                            \n
                          • \u00c9clairage ancien :<\/strong> Sa moelle spongieuse, une fois tremp\u00e9e dans de la graisse animale ou v\u00e9g\u00e9tale, servait autrefois de m\u00e8che pour fabriquer des chandelles \u00e9conomiques (\u00ab\u00a0chandelles de jonc\u00a0\u00bb).<\/span><\/li>\n<\/ul>\n<\/div>\n
                            \n
                              \n
                            • Ornementation :<\/strong> Tr\u00e8s appr\u00e9ci\u00e9 au bord des bassins de jardin. Il existe une vari\u00e9t\u00e9 horticole c\u00e9l\u00e8bre, le Juncus effusus ‘Spiralis’<\/em> (jonc tire-bouchon), dont les tiges s’enroulent sur elles-m\u00eames de fa\u00e7on totalement extravagante.<\/span><\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
