Vegetative Growth
6-10 weeksPlant develops bushy mound shape with narrow, silvery-green foliage; no flowers yet
Allow to establish strong root system; water sparingly; pinch tips in early growth to encourage branching and compact form
Flowering
6-12 weeks (June-August in Northern Hemisphere)Compact mound produces abundant spike-like inflorescences with tiny purple-blue flowers clustered densely along stems
Deadhead spent flowers to encourage continuous blooming; ensure good air circulation; do not fertilize (promotes leggy growth)
Seed Development & Maturation
8-12 weeksFlowers fade to tan seed heads; foliage remains silvery-green and aromatic; plant hardens off for dormancy
Can leave seed heads for wildlife and winter interest, or harvest for seeds; reduce watering; avoid pruning after August
Dormancy
3-4 monthsPlant enters winter rest with minimal visible growth; foliage darkens slightly but remains evergreen

Harvest Tips
Harvest flowers at peak bloom when just opening but before fully mature for best fragrance. Cut flower spikes in morning after dew dries. Dry hanging upside-down in dark, airy location for 2-3 weeks. For essential oil, harvest mid-bloom. Deadheading spent flowers encourages more blooms and maintains compact shape.
Fun Facts
- 🌱 Compacta lavender was selected and bred specifically to create a dwarf cultivar perfect for containers and small garden spaces while maintaining the full fragrance and ornamental appeal of larger English lavender varieties.
- 🌱 Lavender has been cultivated for over 2,500 years and was used by ancient Romans in bath water; the name 'lavender' comes from the Latin 'lavare,' meaning 'to wash.'
- 🌱 The essential oil in lavender is produced in tiny glands on the flowers and leaves; drought conditions and stress actually increase oil concentration, making lavender more fragrant under drier growing conditions.
