Picture of a three-dimensional simulated flower bed

Quick answer：

A three-dimensional simulated flower bed is a decorative item designed to look like a natural garden but without the need for real plants. It is commonly used in areas where real plants cannot be maintained, such as indoors or in urban environments. These flower beds are typically made from materials like plastic, rubber, or glass fiber, which can be painted to resemble various types of flowers and plants. They are a popular choice for garden enthusiasts and interior decorators looking for an easy-to-maintain and visually appealing alternative to live plants.
