The design of a ship-shaped three-dimensional flower bed involves creating a landscape feature that mimics the form of a ship. This can include elements like sails, masts, and hull shapes, often made with plants, hedges, and other landscaping materials. Such designs are popular in gardens, parks, and public spaces, providing both aesthetic appeal and a sense of scale. They require careful planning for the selection of plants that can withstand the weather conditions and complement the ship theme.
