What German Easter decoration consists of tree branches covered with decorated eggs?

The German Easter decoration consisting of tree branches covered with decorated eggs is called an Ostereierbaum.

An Ostereierbaum, or Easter egg tree, is made by placing decorated eggs on branches indoors or on a living tree outdoors. The eggs may be painted, carved, blown and emptied, or made from materials such as wood, plastic or glass.

The custom belongs to a wider European tradition of using eggs and spring greenery as seasonal symbols. Eggs represent new life, while budding branches suggest the arrival of spring. In Germany, families and communities display these trees during the weeks around Easter.

The term is sometimes used loosely for any Easter tree. A famous public example was the Saalfeld Easter egg tree in Thuringia, which became widely known for its large collection of decorated eggs before the display ended in 2015.
