A plant holder has a basket formed from a base and a peripheral sidewall around the base. A support arm extends upward from the base at a flat region of the sidewall. A hook at the distal end of the support arm may be inserted into a hole in a vertical surface such as a wall. The basket is then suspended from the support arm and the flat region of the sidewall abuts and is flush with the vertical surface. The support arm may be angled slightly inward toward the center of the basket in order to provide additional force holding the plant holder against the vertical surface it is suspended from.
