How to Grow Catmint from Seed: The Pollinator Magnet You Need

Catmint (Nepeta spp.) is one of the most versatile and underrated garden plants. Its clouds of lavender-purple flowers bloom for weeks, attract bees, butterflies, and hummingbirds in droves, and the plant itself is remarkably tough — drought-tolerant, deer-resistant, and perennial in most climates.

Starting Catmint from Seed

Catmint seeds benefit from cold stratification (2–4 weeks at 35–40°F) for improved germination. After stratification, sow indoors 8–10 weeks before last frost. Surface-sow on a well-draining mix — seeds need light to germinate. Keep at 60–70°F (15–21°C). Germination takes 10–20 days.

Transplanting

Harden off seedlings for 7–10 days. Plant in full sun to partial shade with well-drained soil. Space plants 18–24 inches apart — they spread attractively. Catmint tolerates poor soil and doesn't need fertilizing once established.

Care and Pruning

After the first flush of flowers fades (usually June–July), cut plants back by one-third to one-half. This hard cut triggers a second bloom in late summer or early fall — often as prolific as the first. Water during establishment; once established, catmint is remarkably drought-tolerant.

Why Gardeners Love Catmint

  • Blooms for 8–12 weeks — one of the longest-flowering perennials
  • Deer and rabbit resistant
  • Perfect edging plant — soft, mounding form
  • Loved by bees, beneficial insects, and hummingbirds
  • Fragrant foliage repels aphids naturally

Frequently Asked Questions

Is catmint the same as catnip?

They are related but different. Catnip (Nepeta cataria) is the variety that strongly affects cats. Catmint (Nepeta mussinii or Nepeta racemosa) is the ornamental garden variety with lavender-purple flowers and a more refined appearance. Cats may be attracted to catmint, but less intensely than to catnip.

Does catmint spread aggressively?

Catmint spreads gently by forming a wider clump each year and may self-seed lightly, but it is not considered invasive. It's easily controlled by dividing clumps every 3–4 years or removing self-seeded seedlings.

How do I get catmint to bloom again?

After the first flush of flowers fades, cut the entire plant back by one-third to one-half. This shearing triggers vigorous new growth and a second bloom wave in late summer or early fall, often as impressive as the first.
