2. Description of the Related Art In recent years, so-called gardening for making a garden in a miniature garden style at home has become popular. In this kind of gardening, the arrangement of vegetation is often changed in order to achieve a change of mind. Therefore, conventionally, plants are cultivated in a planter in which a synthetic resin material is formed in a box shape with a bottom, and the planter is moved as necessary to change the arrangement of the plants.

[0003]

However, even if a garden is constructed by arranging a large number of planters, the inorganic outer walls of the planters are conspicuous, causing a sense of incompatibility with plants and trees, and a relatively large gap is formed between adjacent planters. There was a problem that lacked a sense of unity.

Accordingly, the present invention is to solve such a problem, and it is possible to easily rearrange the vegetation without impairing the harmony with the vegetation and the sense of unity as a garden, and to provide a drainage hole . It is an object of the present invention to provide a stepped wall that can be easily formed.
