Seedling/Establishment
2-4 weeksSmall rosette of silvery-green leaves emerges; plant develops root system
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing.
Vegetative Growth
4-8 weeksPlant develops bushy mound of soft, aromatic gray-green foliage; no flowers yet
Water moderately. Pinch back stem tips if you want denser branching. Begin reducing water to encourage hardiness.
Early Flowering
1-2 weeksFirst white flower spikes appear above the foliage canopy
Maintain moderate watering. Light deadheading encourages more blooms. Begin fertilizing lightly if desired.
Peak Bloom
6-12 weeksProlific white flower spikes cover the plant in bright blooms; full fragrant display
Deadhead spent flowers regularly to encourage continuous blooming. Reduce water to minimal levels; drought stress promotes more flowers. No fertilizer needed.
Late Season/Winter Dormancy
Variable by zone; typically 4-8 weeks before hard freezeFlower production slows; foliage remains silvery but may fade; plant prepares for dormancy
Stop deadheading to allow plant to set seeds for wildlife. Cut back in fall or early spring to 4-6 inches. Provide excellent drainage to prevent winter rot.

Harvest Tips
Catmint is not typically harvested as a crop. Deadhead spent white flowers by pinching or cutting just below the flower spike to encourage continuous blooming throughout summer. Cut back the entire plant to 4-6 inches in fall or early spring. Snip foliage anytime for fresh herbal tea or flower arrangements.
Fun Facts
- 🌱 Catmint Snowflake is a sterile hybrid (Nepeta × faassenii), meaning it cannot produce fertile seeds—this actually extends its blooming season since the plant keeps flowering instead of setting seeds.
- 🌱 The silvery-green foliage is aromatic when brushed or crushed, releasing a pleasant, herbal fragrance that deters some garden pests naturally.
- 🌱 Despite being called 'Catmint,' this cultivar is less attractive to cats than common catnip (Nepeta cataria), though some cats still enjoy rolling in it.
