A flower pot includes a first pot, a second pot and a lifting or lowering mechanism. The second pot circles the first pot. The bottom of the second pot has at least one hole. The lifting device includes at least one supporting and the lifting or lowering element. The supporting is through the hole of the second pot and support the bottom of the first pot to support the first pot. The lifting or lowering element drives the second pot and first pot far away or close to form a variable space.一種可拉伸的花盆裝置,包含一第一盆體、一第二盆體及一升降裝置。第二盆體可活動地套設於該第一盆體的下方,該第二盆體底部具有至少一穿孔。升降裝置包含至少一可傳輸土體的支撐管及一升降驅動器。一可傳輸土體的支撐管貫穿該第二盆體的該至少一穿孔並抵壓該第一盆體的底部以支撐該第一盆體。升降驅動器驅動該第二盆體與該第一盆體相對分離生成一可變容置空間。10‧‧‧花盆裝置100‧‧‧第一盆體200‧‧‧第二盆體210‧‧‧穿孔400‧‧‧盆栽填土裝置410‧‧‧升降裝置411‧‧‧支撐管412‧‧‧升降驅動器420‧‧‧填土裝置421‧‧‧載土腔體422‧‧‧流管423‧‧‧流體驅動器430‧‧‧殼體500‧‧‧傳感器S‧‧‧可變容置空間
