Each of these self-watering planters is comprised of interlocking containers, giving them a stable base and an integrated reservoir. The planters are crafted from terracotta, and the upper containers retain their natural colour. The bases are coloured in green, white and dark brown. The water reservoir fills from the side, through an opening large enough to be refilled by a waterspout or hose nozzle. The self-watering function is activated when the upper containers absorb water from the bases below them.
