How to care for Nepeta: expert tips for thriving garden plants

Nepeta, also known as catmint, is a long-flowering and easy-care perennial that brings softness and movement to the garden. With its airy flower spikes and aromatic grey-green foliage, Nepeta is perfect for sunny borders, cottage gardens and pollinator-friendly planting schemes.

Varieties such as Nepeta nervosa ‘Blue Moon’, with its vibrant blue-purple flowers, and Nepeta faassenii ‘Snowflake’, featuring elegant white blooms, provide months of colour from late spring into summer. This hardy perennial is loved for its relaxed appearance and low-maintenance nature.

What are Nepeta plants?

Nepeta is a genus of flowering perennials belonging to the mint family. It is known for its fragrant leaves and abundant flower spikes that attract bees and butterflies.

Nepeta nervosa ‘Blue Moon’ produces upright spikes of deep blue-purple flowers and has a compact, clump-forming habit. Nepeta faassenii ‘Snowflake’ offers soft white blooms that beautifully contrast with its silvery foliage. Both varieties typically grow between 30 and 60 cm tall, making them ideal for the front or middle of a border.

Nepeta is a hardy and reliable plant that returns year after year with minimal care.

When to plant Nepeta

The best time to plant Nepeta is in spring or early autumn. During these seasons, the soil is workable, and temperatures are mild, allowing the roots to establish well.

Spring planting ensures strong growth and flowering in the same year. Autumn planting gives the plant time to root before winter, as long as the soil is not frozen.

How to care for Nepeta

Nepeta is an easy-care perennial that thrives in sunny conditions. Once established, it is drought-tolerant and requires little maintenance.

Light and location

Nepeta grows best in full sun but can tolerate light partial shade. A sunny location encourages compact growth and abundant flowering. It works beautifully in sunny borders, gravel gardens and along pathways where its soft, arching stems can spill gently over edges.

Soil

Nepeta prefers well-draining soil and does not tolerate heavy, waterlogged conditions. Average garden soil is usually sufficient, as long as drainage is good. If the soil is very heavy, improve it with sand or compost before planting. In pots, use high-quality potting soil with good drainage.

Watering

Nepeta is drought-tolerant once established. Water young plants regularly during their first growing season to help them develop strong roots. After that, water during prolonged dry periods, but avoid overwatering. The soil should dry slightly between watering.

Pruning

After the first flowering, cut the plant back by about one-third. This encourages fresh growth and often results in a second bloom later in the season. In early spring, trim back old stems to maintain a neat and compact shape. Regular pruning keeps Nepeta looking fresh and prevents it from becoming too woody.

Winter care for Nepeta

Nepeta is winter hardy in most moderate climates. In autumn, you can leave some of the stems for winter interest and cut them back in early spring.

Ensure the soil drains well during winter, as overly wet conditions can damage the roots. A light layer of mulch can provide extra protection in colder regions.

Where to place Nepeta in the garden

Nepeta is ideal for sunny borders, cottage gardens and pollinator-friendly planting schemes. Its soft, flowing habit pairs beautifully with roses, salvia, lavender and ornamental grasses.

Nepeta nervosa ‘Blue Moon’ adds bold blue tones to mixed borders, while Nepeta faassenii ‘Snowflake’ provides a fresh white accent that brightens planting combinations. It also works well along pathways and in raised beds, where its aromatic foliage can be enjoyed up close.
