Catnip Seeds

Ready to grow a fragrant garden feature for your cat to investigate? Follow our step-by-step Catnip Grow Guide for sowing, germination, transplanting, regional timing and safe ongoing care.

Grow aromatic catnip with soft grey-green foliage and pale flowers in a sunny bed or freely draining pot, where your cat can investigate it under supervision.

Quick Grow Facts

• Plant Type: Usually short-lived herbaceous perennial.
• Scientific Name: Nepeta cataria; no cultivar or series is named on the current listing.
• Seed Form: Raw seed in 1 g and 20 g packs; check the current packet for lot-specific treatment and handling directions.
• General Sowing Time: Spring to autumn, choosing a mild local establishment window.
• Position: Full sun, or light afternoon shade in severe heat, with freely draining soil or potting mix.
• Sow Depth and Light: The listing says 0.5 cm; generic Nepeta guidance differs on whether light is needed, so follow the physical packet if it gives a different direction and never bury more deeply.
• Germination: The listing gives about 7–14 days; aim for a steady medium near 20–24°C and allow longer if conditions fluctuate.
• Spacing: 45 × 30 cm; allow more airflow in humid sites.
• Growth Form: Upright, bushy clump, often about 60–90 cm tall; normally no support is needed.
• Care: Keep new plants evenly moist, then avoid a permanently wet crown. Pinch established tips or shear after flowering for denser growth.
• Harvest: The listing gives 90 days as a planning estimate; weather and establishment can shift timing.
• Pet Safety: The ASPCA lists catnip as toxic to cats because ingestion can cause vomiting and diarrhoea. Supervise access, discourage chewing and contact a veterinarian if your pet seems unwell.

Why Grow Catnip

• Aromatic foliage offers a supervised sensory experience for many cats.
• Grey-green leaves and pale flowers add soft texture to sunny pots and beds.
• A managed container or protected garden spot helps young plants establish before curious pets reach them.

Garden Uses

Plant catnip in a sunny border or a draining pot. Protect young plants from rolling or trampling, and supervise your cat around established foliage.

Growing Notes

• Sow thinly using the physical packet’s depth and light directions; the live listing says 0.5 cm.
• Keep the medium near 20–24°C and evenly moist, never waterlogged, while seed germinates.
• Harden off sturdy seedlings, plant at the listed 45 × 30 cm spacing and shear spent stems after flowering.
