Growing peppermint indoors follows the same basic care as any mint variety, peppermint and spearmint are the two most common choices. For container size, watering, light, propagation, and troubleshooting, see our complete guide to growing mint indoors. This page covers the few things worth knowing that are specific to peppermint.
Quick Ways to Identify Peppermint
Peppermint typically has purplish-tinted stems and darker green leaves, compared to spearmint’s green stems and lighter foliage. Crushing a leaf is the clearest test. Peppermint has a sharp, cooling menthol scent, quite different from spearmint’s sweeter, warmer aroma. For a full breakdown of the flavor chemistry and growing differences, see our dedicated spearmint vs peppermint comparison guide.
Growing Peppermint Indoors from Cuttings
Peppermint (Mentha × piperita) is a sterile hybrid, a natural cross between watermint and spearmint. That means it doesn’t produce viable seed, so it can only be grown from cuttings or division, never reliably from seed. If you see peppermint seeds for sale, know that plants grown from them may not come true to the parent plant’s flavor or characteristics. Our propagating mint guide covers the cutting process in full.
Growing Tendency
Peppermint generally prefers cooler, more consistently moist conditions than spearmint, and is a bit less tolerant of heat and inconsistent watering. It’s still a genuinely easy indoor herb, the main challenge is its vigorous growth habit, not keeping it alive.
Best Uses for Peppermint
Peppermint’s sharp, cooling menthol flavor makes it a natural fit for:
- Tea
- Desserts and chocolate pairings
- Cocktails and drinks where a bold, cooling flavor is wanted
- Aromatherapy and diffusers, for its strong, invigorating scent
Harvesting
Follow the same general harvesting approach covered in our full growing guide, snip stems just above a leaf node rather than pulling leaves individually. Peppermint’s essential oils are most concentrated in the morning, after any dew has dried but before the day heats up, so an early harvest gives you the strongest, most cooling flavor. Harvesting just before the plant starts to flower also tends to yield the most potent leaves.
Before You Go – Growing Peppermint Indoors
Growing peppermint indoors takes the same basic care as any mint. The main things worth knowing specifically about peppermint are that it can only be started from cuttings or division, not seed, and it prefers slightly cooler, more consistent moisture than some other mint varieties.
