Decorative containers for indoor-use like tall ceramic planters need to be watertight without any holes for drainage. Otherwise, the leakage will damage your carpeting or floor finishes. Ceramic is the best material for indoor planters as it breathes or sweats. But, you'll also need a plastic liner that's watertight to be placed inside the planter. If you'll be purchasing a container with holes, make sure you fill the holes with epoxy or any other waterproof material to ensure no damage is caused to your home.
