Deciduous forest in autumn

Deciduous forest in winter

Mixed deciduous forest in spring

Deciduous plants in mid- to high latitudes shed their leaves as temperatures drop in autumn.

Deciduous means "temporary" or "tending to fall off" (deriving from the Latin word decidere, to fall off).When talking about plants this means that the plant loses its leaves, usually in autumn. The leaves will then grow again in spring.

When referring to teeth, it means the teeth at the front of the mouth that grow and fall out and are replaced in childhood. They are called deciduous teeth.
