The purpose of the present invention is to provide a bottom member of a planter in which the occurrence of rot, mold, and the like in a side wall lower-end side of a planter having a wooden side wall can be suppressed to improve durability, and a highly durable planter that uses this bottom member. Mounted on a side wall member 1, which is made of a wooden material and shaped as a cylinder open in the top and bottom, is a bottom member 2 made of a synthetic resin and provided with an undersurface cover portion 3 that has a lower end receiving part 32 for receiving the lower end surface of the side wall member 1 and that has a ring shape as seen in plan view, an outer wall cover part 4 interconnected with the undersurface cover portion 3 and arranged so as to cover the outer peripheral surface of the lower end part of the side wall member 1, and a bottom portion 5 interconnected with the interior of the undersurface cover portion 3 and having a water-draining hole. The bottom member 2 is mounted so that the lower end opening of the side wall member 1 is closed by the bottom portion 5, the undersurface of the side wall member 1 is covered by the undersurface cover portion 3, and the outer periphery of the lower end part of the side wall member 1 is covered by the outer wall cover part.La présente invention se donne pour objectif de fournir un élément inférieur d'une jardinière dans laquelle il est possible de supprimer la pourriture, la moisissure et autre apparaissant dans le bord inférieur de la paroi latérale d'une jardinière à parois latérales en bois pour en améliorer la durée de vie, et une jardinière extrêmement durable qui utilise cet élément inférieur. Monté sur un élément de paroi latérale 1, qui est constitué d'un matériau en bois et de forme cylindrique ouvert dans la partie supérieure et la partie inférieure, figure un élément inférieur 2 fait d'une résine synthétique et pourvu d'une partie de revêtement superficielle inférieure 3 qui a une partie réceptr
