\"Grevillea1\"<\/a> On ne les voit pas beaucoup dans les jardins et cela tient s\u00fbrement au fait que les gr\u00e9vill\u00e9as<\/a> ne sont pas rustiques, il n’y a que dans le midi qu’ils peuvent passer l’hiver en plein air. En dehors de cette zone, on peut les cultiver en bac et les abriter pendant les mois les plus froids, cela serait dommage de se priver d’une floraison<\/a> aussi spectaculaire qu’originale, d’autant qu’elle dure plusieurs mois.<\/p>\n

Pour finir de vous convaincre, j’ajoute que ces plantes ont un feuillage  persistant qui est fin et attrayant.
Alors, n’h\u00e9sitez pas, installez dans un grand pot ce petit arbuste d’origine australienne, vous ne le regretterez pas. <\/p>\n

Il y a pr\u00e9s de 200 esp\u00e8ces connues de grevillea, elles ont des feuilles diff\u00e9rentes et des coloris de fleurs vari\u00e9s. Grevillea juniperus<\/a> est le plus facile \u00e0 cultiver et le plus r\u00e9pandu, ses feuilles sont fines et ses fleurs bien rouges, grevillea robusta<\/a> \u00e0 un feuillage qui fait penser \u00e0 celui des foug\u00e8res et porte des fleurs jaune-orang\u00e9. Autre esp\u00e8ce bien connue, grevillea rosmarinifolia dont les feuilles ressemblent \u00e0 celles du romarin, ses fleurs sont bien rouges.
Ces plantes aiment les sols frais, le soleil, mais n’appr\u00e9cient pas les arrosages \u00e0 l’eau calcaire qui d\u00e9clenchent chez eux une chlorose au niveau des feuilles.
Vous pouvez faire des semis au printemps pour avoir des pieds de grevilleas, si vous faites tremper les graines avant de les planter vous obtiendrez un meilleur r\u00e9sultat.
Le bouturage? Possible bien s\u00fbr mais en \u00e9t\u00e9 et \u00e0 l’\u00e9touff\u00e9e car il faut chaleur et humidit\u00e9 pour que la tige coup\u00e9e prenne racine.<\/p>\n","protected":false},"excerpt":{"rendered":"
