A hanging planter is commonly referred to as a hanging basket or hanging pot. These planters are designed to be suspended from the ceiling, a hook, or a railing, allowing plants to hang down, which is especially useful for saving space or creating a cascading effect. They can come in various materials like wicker, plastic, ceramic, or metal, and are often used for flowers, vines, or trailing plants.

Key Features of Hanging Planters:

1. Suspension: These planters typically come with a chain, rope, or cord for hanging.
2. Space-saving: Ideal for small spaces, patios, or indoors where floor space is limited.
3. Aesthetic Appeal: They add a vertical dimension to gardening, perfect for decorative plants or hanging flowers.

Sometimes, they may also be referred to as hanging pots, hanging flower baskets, or hanging garden planters, depending on their design and intended use.
