Flower pot

A container assembly for growing and transplanting plants comprising, in combination, a pot having an open top end, an open bottom end, an upwardly flaring conical sidewall disposed between the top and bottom ends, and an annular flange projecting into the interior of said pot from the sidewall near the bottom end defining the open bottom end, said flange being inwardly, radially spaced from said sidewall;

• bottom disc removably supported on the annular flange within the interior of said pot and covering the open bottom end, said bottom disc having at least one drainage opening overlying the open bottom end for permitting water to drain from soil enclosed within said pot through the open bottom end, and said bottom disc being upwardly movable through said pot for displacing a volume of soil and a rooted plant through the top opening without disturbing the soil surrounding the roots of the plant;
• a tray for supporting said pot in an upright position, said tray having a closed bottom panel and an upturned sidewall projecting from the closed bottom panel, said tray bottom panel, tray sidewall and pot sidewall defining an open annular reservoir space between the sidewall of the tray and the sidewall of the pot when the pot is received within the tray;
• and, interlocking support means mounted on said pot and on said tray for centering and removably supporting the open bottom end of said pot above the bottom panel of said tray and below the top of the tray sidewall and for providing fluid communication between the open reservoir space and the intermediate opening, said interlocking support means including a circular array of axially projecting feet depending from said flange, said feet being spaced relative to each other thereby defining a flow passage between adjacent feet, and a circular array of elongated, curved ridge segments projecting upright from the tray bottom panel, said curved ridge segments being spaced relative to each other thereby defining a flow passage between adjacent ridge segments, the circular array of axially projecting feet being concentrically aligned with the circular array of ridge segments, said axially projecting feet and ridge segments being engageable to define a male and female connection for securing said pot into engagement with said tray.
