Abstract: A stackable planter comprising a plurality of planter trays has planter cups at a periphery for holding soil and plants. An inner rib of each planter tray defines a center portion of the planter tray. The center portion of one of the planter trays has a bottom wall that extends across the center portion and defines a recess for holding soil, whereby one or more plants may be planted in the center of the stackable planter. The planter trays are shaped to nest within one another when in a collapsed configuration. The stackable planter may be used indoors or outdoors and is portable in nature. Further configurations of the planter may provide a watering device with features configured to fit within the center portion of a planter trays.
