Nepeta ‘Cat’s Pajamas’: A Compact Catmint That Delivers Big Landscape Impact
In recent years, Nepeta ‘Cat’s Pajamas’ has become one of the most celebrated perennial introductions in the gardening world. Named the 2021 Perennial Plant of the Year, this compact catmint is loved for its long bloom period, drought tolerance, tidy growth habit, and ability to attract pollinators.
Unlike older catmint varieties that can become floppy and spread into neighboring plants, ‘Cat’s Pajamas’ maintains a compact, rounded form while producing masses of vibrant lavender-blue flowers from late spring through fall.
Origins of Nepeta ‘Cat’s Pajamas’
‘Cat’s Pajamas’ is a modern hybrid cultivar of Nepeta, a genus containing approximately 250 species native to Europe, Asia, and Africa. Catmints belong to the mint family (Lamiaceae) and are known for their aromatic foliage and pollinator-friendly flowers.
This cultivar was bred to improve upon traditional catmints by producing flowers along the entire length of the stem rather than only at the top. The result is a dense mound of colour that begins blooming earlier and lasts longer than many older varieties.
Why ‘Cat’s Pajamas’ Makes an Outstanding Landscape Plant
Long Bloom Season
One of the greatest strengths of this plant is its extended flowering period.
The indigo-blue to lavender-blue flowers begin in late spring and continue through much of the summer, especially when lightly sheared after the first flush of blooms.
Compact Growth Habit
Unlike some larger catmints that sprawl, ‘Cat’s Pajamas’ forms a neat, rounded mound.
Typical mature size:
- Height: 30–35 cm (12–14 inches)
- Spread: 45–50 cm (18–20 inches)
Its tidy habit makes it ideal for modern residential landscapes.
Pollinator Magnet
The flowers attract:
- Bees
- Butterflies
- Hummingbirds
- Other beneficial insects
This makes it an excellent addition to pollinator gardens and wildlife-friendly landscapes.
Deer and Rabbit Resistance
The aromatic foliage helps deter browsing by deer and rabbits, making it a dependable plant for rural and suburban landscapes.
Landscape Uses
Border Plantings
Its compact size makes it perfect along the front of perennial borders where it creates a continuous ribbon of colour.
Edging Pathways
Plant it along walkways, driveways, or garden paths for a soft, colourful edge.
Pollinator Gardens
Its abundant flowers provide valuable nectar throughout the growing season.
Rose Companions
Catmint is frequently planted beneath roses because its cool blue flowers complement rose colours while helping disguise bare lower stems.
Mass Plantings
Groups of ‘Cat’s Pajamas’ create striking drifts of colour in landscapes.
Gravel and Xeriscape Gardens
Its drought tolerance makes it ideal for low-water landscapes and rock gardens.
Growing Conditions and Care
Sunlight
For best flowering, plant in:
Full Sun (6+ hours daily)
It will tolerate light shade, but flowering is typically strongest in full sun.
Soil Requirements
‘Cat’s Pajamas’ thrives in:
- Well-drained soil
- Sandy soils
- Gravelly soils
- Average garden soils
It actually performs better in moderately poor soils than in overly rich soils.
Watering
Water regularly during establishment.
Once established, the plant is highly drought tolerant and generally requires little supplemental irrigation except during extended dry periods.
Fertilizing
Minimal fertilization is required. Excess fertilizer may encourage weak growth and reduce its naturally compact habit.
Pruning and Maintenance
Maintenance is simple:
- Remove spent flower spikes after the first major bloom.
- Lightly shear plants to encourage reblooming.
- Divide mature clumps every few years if necessary.
This simple maintenance routine often results in flowers for much of the growing season.
Common Pests and Diseases
One reason landscapers love this plant is that it is generally very trouble-free.
Possible Pests
Occasionally you may encounter:
- Aphids
- Spider mites
- Whiteflies
- Leafhoppers
These problems are usually minor and rarely threaten established plants.
Possible Diseases

Good drainage and proper spacing typically prevent serious disease problems.
