Abstract: A flowerpot includes a main body and a water conservation arrangement. The water conservation arrangement includes a plurality of ventilating holes formed on a lower portion of the main body, at least one through drainage hole formed on the main body, a control valve provided on the drainage hole, and a plurality of selective passage members attached on an inner surface of the main body to completely cover the ventilating holes respectively. Each of the selective passage members is configured to have a predetermined water permeability and a predetermined air permeability. When a predetermined amount of soil and water are disposed in the receiving cavity, the water is substantially conserved in the received cavity for being absorbed by the plant.
