A cloche, or bell, is a type of bell-shaped cover often used in gardening. It is designed to protect plants from cold weather and pests while allowing sunlight to reach them. Made from glass or plastic, a cloche creates a mini-greenhouse effect, helping to maintain warmth and humidity around the plants. In addition to gardening, the term "cloche" can also refer to a style of hat that is fitted and bell-shaped, popularized in the early 20th century. This hat style is often associated with the flapper era and is characterized by its close fit and soft, rounded shape.
