Abstract: A planter is provided, which includes a container for holding plants, which is mounted on a window pane from attachment positions outside the periphery of the container's silhouette on the window. The container includes a planar surface that rests against the window. At least two mounting elements, e.g., suction cups, attach to the window. The container is hung from a flexible strand(s) which loop through and/or terminate at rings or apertures on the container. The other end of the strand(s) attaches to the mounting elements. The horizontal and/or vertical positioning of the container can be adjusted in situ. The planter can include a plurality of containers hung in various configurations from two or more mounting elements. The containers can be formed from (synthetic) stained glass, ceramic, or other decorative material and filled with clear or colored synthetic soil. The flexible strands are also decorative and formed, for example, from macramé.
