A cachepot is a French term for what is usually called in modern English a “planter”, namely a decorative container or “overpot” for a plant and its flowerpot, for indoors use, usually with no drainage hole at the bottom, or sometimes with a matching saucer. It is intended to be more attractive than the terracotta flowerpot in which the plant grows, and to keep water off furniture surfaces. This is a whimsical example standing 5 ½” with a 6 ½” opening.
