How Big Does Catmint Grow?

Catmint size can vary depending on the specific variety you choose. Most traditional catmint plants form attractive, bushy mounds. Their typical size ranges from 30cm to over 90cm tall, with a similar or slightly wider spread. This makes catmint suitable for many uses, from edging pathways to filling sunny garden beds.

For example, Nepeta faassenii usually reaches about 40-45cm tall and can spread up to 60cm, making it excellent for softening the edges of garden beds. Nepeta mussinii (Catmint) is particularly popular for its dense growth habit and similar dimensions, making it an ideal candidate for compact spaces.

Popular Catmint Varieties and Their Sizes

Nepeta 'Six Hills Giant'

If you’re searching for larger impact, Nepeta 'Six Hills Giant' (Catmint) is one of the tallest varieties. It typically grows up to 90cm tall with an impressive spread of about 1 metre, perfect for making a statement or as a relaxed informal hedge in sunny borders.

Nepeta 'Walkers Low'

For a mid-sized option, Nepeta 'Walkers Low' (Catmint) forms neat, clumping mounds around 60cm to 75cm high and wide. The name can be a little confusing, as this variety is not as low-growing as it sounds. It’s an excellent choice for lining paths or mixing with roses and perennials.

Nepeta 'Blue Wonder'

If you have limited space or are working with containers, Nepeta 'Blue Wonder' (Catmint) is a more compact variety, usually reaching 30-40cm tall. Despite its smaller size, it offers all the classic catmint benefits—fragrant foliage, long flowering season, and excellent drought tolerance.

How to Choose the Right Catmint Size for Your Garden

Selecting the ideal catmint size depends on your garden’s scale and your planting goals. For low edges and lining paths, choose smaller varieties like Nepeta faassenii or Nepeta 'Blue Wonder' (Catmint). For greater coverage and presence, the larger Nepeta 'Six Hills Giant' (Catmint) and Nepeta 'Walkers Low' (Catmint) will suit best.

No matter which catmint size fits your space, these hardy perennials are sure to attract bees and butterflies, thrive in New Zealand’s conditions, and bring months of soft blue flower spires to your garden.
