Catmint

Nepeta racemosa is native to the Caucasus region, Turkey, Iran, and parts of Central Asia, where it grows wild on dry hillsides, rocky slopes, and open scrubland.

• The genus Nepeta comprises approximately 250 species distributed across Europe, Asia, and Africa, with the greatest diversity in the Mediterranean and Western/Central Asian regions
• Nepeta racemosa was introduced to European horticulture in the early 19th century and has since become one of the most widely cultivated species in the genus
• Numerous cultivars have been developed, including the popular 'Walker's Low,' which was named Perennial Plant of the Year in 2007 by the Perennial Plant Association
• The plant has naturalized in parts of Europe and North America outside its native range

Nepeta racemosa is a clump-forming, herbaceous perennial typically growing 30–60 cm tall and spreading 45–90 cm wide.

Stems & Foliage:
• Stems are square in cross-section — a characteristic feature of the Lamiaceae family
• Leaves are opposite, ovate to heart-shaped, 2–5 cm long, with serrated margins
• Foliage is soft, grey-green to sage-green, and densely covered with fine hairs (pubescent)
• When crushed, leaves release a strong, pungent, minty fragrance due to volatile essential oils

Flowers:
• Small, tubular, two-lipped flowers (~1–1.5 cm long) in shades of lavender, blue, or violet
• Arranged in dense terminal and axillary racemes or spike-like clusters
• Calyx is tubular with five teeth, often tinged purple
• Corolla is bilabiate (two-lipped): upper lip erect, lower lip spreading with a larger central lobe
• Blooms prolifically from late spring through summer, often reblooming if sheared back after the first flush

Root System:
• Fibrous, spreading root system with short rhizomes
• Can form dense clumps over time but is generally less aggressively spreading than true mints (Mentha)

Catmint thrives in open, sunny habitats with well-drained soils and is remarkably drought-tolerant once established.

• Native habitat includes dry grasslands, rocky slopes, and open woodland margins at elevations up to ~2,000 m
• Prefers full sun but tolerates light shade
• Highly attractive to pollinators — a magnet for bees, butterflies, and hoverflies
• The extended blooming period provides a valuable nectar source from late spring into summer
• Deer and rabbit resistant due to the strong aromatic oils in the foliage
• Tolerates poor, sandy, or gravelly soils and is well-suited to xeriscaping

Catmint is one of the easiest and most forgiving perennials to grow, making it ideal for beginner gardeners and low-maintenance landscapes.

Light:
• Full sun (minimum 6 hours of direct sunlight per day) for best flowering and compact growth
• Tolerates partial shade but may become leggy and produce fewer blooms

Soil:
• Adaptable to a wide range of soil types — sandy, loamy, or rocky
• Requires well-drained soil; does not tolerate waterlogged or heavy clay conditions
• Tolerates poor, nutrient-deficient soils
• pH range: 6.0–8.0 (slightly acidic to slightly alkaline)

Watering:
• Drought-tolerant once established; overwatering is a more common problem than underwatering
• Water regularly during the first growing season to establish roots
• Thereafter, supplemental watering is rarely needed except during prolonged dry spells

Temperature:
• Hardy in USDA zones 4–8 (tolerates winter temperatures down to approximately −34°C)
• Performs well in hot summers but appreciates good air circulation in humid climates

Pruning & Maintenance:
• Shear back by half after the first bloom to encourage a second flush of flowers and maintain a tidy, compact form
• Cut back to the ground in late autumn or early spring
• Deadheading spent flower spikes prolongs the blooming season

Propagation:
• Division in spring or autumn
• Softwood cuttings in early summer
• Seeds can be sown in spring, though cultivars may not come true from seed

Common Problems:
• Generally pest- and disease-free
• May develop root rot in poorly drained or overly wet soils
• Can become floppy or open-centered in too much shade or overly rich soil
• Foliage may decline in peak summer heat in very humid climates — a light shearing refreshes the plant
