ABSTRACT:
This is a watering system for a stand for a botanical specimen. The watering system includes an ornamental reservoir from which a water hose and an air hose extend. The hoses have terminal ends which are positioned in the container of the stand. The container is filled with water and the terminal ends are cut on a bias. As the water in the container is depleted, the biased terminal end of the air hose is opened to the atmosphere causing water to flow from the reservoir to the container through the water hose. The watering system could also use a single hose of greater diameter than either of the hoses of the first embodiment. The terminal end of the hose is positioned in the container and is cut on a bias. As the water in the container is depleted, the biased terminal end of the hose is opened to the atmosphere causing water to flow from the reservoir to the container through the bottom half of the hose.
