A flower pot having a removable base, comprising: a basin-shaped main body, with its bottom portion or side wall provided with at least an opening, and at least a female connection piece disposed on said basin-shaped main body and around perimeter of said opening and at least a removable base, having a male connection piece disposed thereon corresponding to said female connection piece, such that the removable base penetrates through said opening and is connected to said basin-shaped main body through connecting said male connection piece to said female connection piece. When a plant in said flower pot has grown up to a certain extent and requires more space, said removable base can be removed, such that the roots of a plant in said flower pot may grow and expand through said opening to a new flower pot, hereby saving the effort and trouble of transplanting.
