A planter is a container typically used for growing plants and flowers. It can be made of various materials such as plastic, ceramic, or wood. Planters come in different shapes and sizes, and are commonly used for home gardening or to add greenery to outdoor and indoor spaces. They often have drainage holes to prevent water from accumulating and causing root rot.

One can purchase a planter box online from Amazon, Lowes and Garden Centres. A planter box is used to place soil inside and plant seeds to grow into plants or simply put plants in straight away. Some can be window boxes inside or larger ones outside.
