To provide a post holder attached to a flowerpot designed so as to readily attach the post to the flowerpot to support a plant in the flowerpot.
The post holder attached to the flowerpot is structured so as to attach a post support 2 to the flowerpot 1. The holder makes it possible to thrust a post 4 into the soil in the flowerpot through the axis hole of the post support 2, and to maintain the post 4 standing by itself with supporting power of the soil and the support via the post support 2. The structure of the holder enables a user to set up her (his) desired number of the posts 4 through attaching the post support 2 in accordance with the desired number of the posts to be set. Rigidity of the post 4 is improved through connecting the posts 4 with each other at the upper part of the post 4 using a fixing ring 6.
