Self-watering planter for use with flood floors

A self-watering planter, comprising:

• an interior cavity defined by a wall and a bottom surface;
• a plurality of drainage risers extending from the bottom surface within the interior cavity, each drainage riser having a tapered shape, a centrally disposed drainage opening, and a plurality of vertically disposed slits in fluid communication with the centrally disposed drainage opening;
• a recess formed on an external portion of the bottom surface, the recess configured to form a cross-shaped channel formed under the bottom surface when the self-watering planter interfaces with a supporting surface, wherein the centrally disposed drainage opening is in fluid communication with the cross-shaped channel;
• a reservoir region formed between the bottom surface and a lower edge of each of the plurality of vertically disposed slits to store water;
• and
• a centrally disposed support structure disposed in a central region on the external portion of the bottom surface, the centrally disposed support structure configured to prevent sag to maintain the cross-shaped channel when the self-watering planter interfaces with the supporting surface;
• wherein the cross-shaped channel provides an opening for flood floor water to enter the interior cavity and be stored in the reservoir region;
• wherein an opening is at an end of the cross-shaped channel and a cross section of the opening is lar ger than a cross section of the cross-shaped channel.

A self-watering planter, comprising:

• an interior cavity defined by a wall and a bottom surface;
• a plurality of conical drainage risers extending from the bottom surface within the interior cavity, each drainage riser having a centrally disposed drainage opening and vertically disposed slits in fluid communication with the centrally disposed drainage opening;
• a cross-shaped recess formed on an external portion of the bottom surface, the cross-shaped recess configured to form a cross-shaped channel formed under the bottom surface when the self-watering planter interfaces with a supporting surface, wherein each centrally disposed drainage opening is in fluid communication with the cross-shaped channel;
• a reservoir region formed between the bottom surface and a lower edge of the vertically disposed slits to store water;
• a permeable tray supported above the bottom surface by a plurality of supports and configured to receive a plant or growing medium, the permeable tray including a plurality of perforations to allow water and air flow;
• a centrally disposed support structure disposed in a central region on the external portion of the bottom surface within the cross-shaped recess, the centrally disposed support structure configured to prevent sag to maintain the cross-shaped channel when the self-watering planter interfaces with the supporting surface;
• and
• peripheral supports disposed on the external portion of the bottom surface, wherein the peripheral supports and the centrally disposed support structure include feet to provide stability and extend a clearance distance with the supporting surface;
• wherein the cross-shaped channel provides an opening for flood floor water to enter the interior cavity and be stored in the reservoir region;
• wherein an opening is at an end of the cross-shaped channel and a cross section of the opening is larger than a cross section of the cross-shaped channel.
