Catmint Basics

If you’re searching for a fuss-free perennial that offers beauty and resilience, catmint is a top contender. Unlike catnip (though related), catmint is better-behaved and less likely to attract feline visitors. Its aromatic, silvery-green leaves and dense clusters of violet to blue flowers bloom from late spring into summer, with some varieties offering repeat flushes through fall. Catmint’s drought tolerance and deer resistance make it an all-star for both experienced and novice gardeners.

Popular Catmint Varieties

Catmint boasts a wealth of cultivars, each offering unique attributes in terms of size, bloom color, and growth habit. Here’s a look at some of the most popular types:

Newer hybrids such as ‘Purrsian Blue’ and ‘Junior Walker’ offer improved disease resistance, compact size, and non-flopping habits, making them ideal for small gardens or containers.

How to Plant Catmint

Catmint is forgiving but thrives best when proper planting guidelines are followed. Whether you’re growing catmint from seeds, purchasing young plants, or using bare roots, a few essentials ensure quick establishment and vigorous growth.

Where to Plant

• Choose a location with full sun for maximum blooming, though partial shade is tolerated in hot climates.
• Ensure soil is well-draining; avoid heavy clay and waterlogged areas which can cause root rot.
• Catmint is suitable for borders, raised beds, rock gardens, and as a ground cover.

When to Plant

• Plant in spring after the last frost or in early autumn before the first hard frost.
• Container-grown plants can be planted during summer if watered regularly until established.

How to Plant

• Space catmint plants 12–24 inches apart, depending on the mature spread of the variety.
• Dig a hole as deep as the plant’s root ball and twice as wide.
• Mix in a little compost if the soil is very poor, but avoid heavy fertilization which can cause lanky growth.
• Set the plant at the same depth as it was in its container. Backfill with soil and water thoroughly.
• Apply a light mulch to conserve moisture and suppress weeds, but avoid piling mulch against the stems.

Growing from Seed

• Catmint can be grown from seed, but many hybrids may not come true or are sterile.
• Start seeds indoors 6–8 weeks before the last frost. Sow thinly, lightly covering seeds, and keep moist at 65–70°F.
• Transplant seedlings outdoors after hardening off and when all danger of frost has passed.

Catmint Care and Maintenance

Catmint’s reputation as a low-maintenance perennial is well-deserved, but a few routine tasks will keep it looking and flowering its best throughout the season.

Watering

• Newly planted catmint needs consistent moisture until established (first growing season).
• Once mature, catmint is drought-tolerant and only needs watering during prolonged dry spells.

Feeding

• Generally, feeding is unnecessary if soil is moderately fertile.
• In very poor soils, a light application of compost in spring can help support vigorous growth.

Pruning and Deadheading

• Deadhead spent blooms regularly to prolong blooming and encourage rebloom.
• Shear plants back by about one-third after the first major flush of flowers fades. This rejuvenates foliage and can stimulate a second bloom.
• Cut back stems to ground level in late fall or early spring to tidy up plants and promote healthy new growth.

Mulching

• Apply a thin layer of mulch to retain moisture, suppress weeds, and protect roots from extreme cold.
• Avoid letting mulch touch plant stems to prevent rot.

Dividing Catmint

• Catmint can become woody or crowded after a few years; divide every 3–4 years in spring or fall to refresh the plant and maintain vigor.

Pest and Disease Resistance

• Catmint is remarkably resistant to most pests and diseases, including deer and rabbits.
• Occasional powdery mildew may appear if plants are overcrowded or grown in shade; provide good air circulation and avoid overhead watering.

Landscaping with Catmint

Catmint’s billowy form, aromatic foliage, and long-lasting flowers make it one of the best perennials for mixed borders, cottage gardens, and pollinator-friendly landscapes. Here’s how to use it effectively in your garden:

• Edging and Borders: Use compact varieties to edge walkways, borders, or garden beds for a soft, cascading effect.
• Pollinator Gardens: Plant in swaths to entice bees, butterflies, and other beneficial insects.
• Rose Companions: Catmint is a classic underplanting for roses, helping deter aphids and soften the edges of formal beds.
• Rock Gardens and Slopes: Drought-tolerant and tough, catmint adapts well to rocky or sloped areas.
• Containers: Dwarf types thrive in pots if drainage is good; combine with other sun-lovers for season-long color.
• Low Maintenance Mass Plantings: Use catmint in drifts or groupings for minimal-care ground cover that blooms for months.

Frequently Asked Questions (FAQs)

How is catmint different from catnip?

Catmint and catnip are both Nepeta species, but catmint (Nepeta ×faassenii and related hybrids) is more ornamental and less attractive to cats, while catnip (Nepeta cataria) has a much stronger effect on felines and is grown primarily for them.

Is catmint invasive?

Most modern catmint hybrids are not invasive and stay within their boundaries when properly maintained. Unlike true mint, catmint rarely spreads aggressively, especially the sterile varieties.

Do I need to prune catmint?

Yes, regular deadheading and shearing after the first bloom keeps catmint tidy, encourages fresh growth, and prolongs the flowering season.

Does catmint attract pollinators?

Absolutely. Catmint is one of the best plants for attracting bees, butterflies, and hoverflies, making it invaluable in supporting pollinator populations.

Is catmint deer-resistant?

Yes, catmint’s aromatic foliage deters deer and rabbits, making it a reliable choice for gardens with wildlife browsing pressure.

Can I grow catmint in containers?

Compact varieties grow well in pots with excellent drainage and full sun. Be sure to water regularly, as containers dry out faster than garden beds.

What are the best companion plants for catmint?

Excellent companions include roses, salvia, coreopsis, yarrow, lavender, and ornamental grasses. Catmint’s cool tones and soft texture mix well with bold or architectural plants.

How do I divide catmint?

Every few years, dig up the clump in spring or autumn, slice the root ball into sections (each with stems and roots), and replant at original depth. Water thoroughly to help divided plants establish.

Does catmint have medicinal uses?

Historically, some Nepeta species have been used in herbal remedies and teas. However, the primary use in gardens today is ornamental.

Catmint is an adaptable, enduring perennial that deserves a spot in any sunny border or pollinator garden. With its resilient nature, extended bloom time, and wildlife-friendly flowers, it’s a must-have for low-maintenance, high-impact gardening.
