4-6 weeksBushy growth with increasingly prominent variegated foliage; multiple stems develop from the base.
Pinch back growing tips to encourage bushier growth. Ensure consistent water supply. Variegation intensifies with adequate light.
Pre-flowering
2-3 weeksPlant reaches mature size with dense foliage; flower buds begin to form at stem tips.
Continue regular harvesting to extend vegetative growth. Pinch off early flower buds if foliage production is priority.
Flowering
4-8 weeksPurple-pink flower spikes emerge from leaf axils; blooms attract bees and butterflies.
Flowers are edible and can be harvested for garnish. Deadhead spent flowers to encourage continued blooming.
Seed Set & Dormancy
Variable; extends into fall/winterFlowers mature into seed capsules; plant begins to slow growth as temperatures cool (in cooler zones).
Allow some flowers to set seed for self-propagation if desired. Cut back plant by half in fall to encourage spring regrowth.

Harvest Tips

Fun Facts
- 🌱 Mentha aquatica 'Variegata' is sometimes called 'Peppermint' mint or 'Bergamot Mint' due to its complex aromatic profile that blends mint, citrus, and floral notes—quite different from common spearmint.
- 🌱 The variegation in the foliage results from variegated chlorophyll production and is best maintained through vegetative propagation (cuttings or division); seeds from variegated plants typically revert to solid green.
- 🌱 Water mint has been used since ancient times and was historically strewn on floors in medieval homes to mask odors and repel insects; it's hardy enough to naturalize along stream banks and pond edges.
