If you’re looking for a low-maintenance, hardy perennial, catmint (Nepeta) is an excellent choice. Often confused with catnip because of their similarities, catmint distinguishes itself with rich purple blooms and is valued more for its decorative appeal rather than its herbal use. As part of the mint family, it also features the characteristic aromatic leaves that make these plants so beloved.

Catmint is a great team player in the garden. Cats adore it, and many plants thrive next to it. By carefully choosing plants that match its growing conditions and aesthetic, you can design a seamless and thriving garden environment.

When selecting companion plants for catmint, consider factors like plant height, growth patterns, and space needs. Here are 21 companion plants that are perfect partners for catmint.
