PURPOSE: To prevent falling of a flowerpot only by fxtting a flowerpot in a frame regardless of the kind of trees and flowering plants planted in a pot.

CONSTITUTION: A flowerpot 10 is fitted in a conical supporting frame 20, one end of which is pressed to the uper outer periphery of a flowerpot 12 in such a manner as to surround the same, the other end side having an earthing portion larger than the outer form of the flowerpot 12. Thus, the flowerpot 10 can be held simply and surely only by fitting the flowerpot 10 in the supporting frame 20. When the flowerpot is fitted in the supporting frame 20, the flowerpot 10 is out of contact with the ground, so that ventilation is improved through a hole provided in the base of the pot and noxious insects are almost prevented from entering from the ground so as to produce an insect control effect. As the supprting frame 20 protects the outer periphery of the pot, the pot can be prevented from being soiled, so that it becomes easy to take the flowerpot 10 placed outside into the interior of a room.
