Seedling
2-3 weeksTiny seedlings with first true leaves emerging; very delicate and small.
Keep soil moist; provide bright light and warmth (65-75°F). Seedlings are slow to establish, so patience is needed.
Vegetative
4-6 weeksCompact plant developing multiple stems; distinctive white-variegated edges on green leaves becoming more pronounced.
Pinch back growing tips to encourage bushier growth. Keep soil moist. Begin harvesting small amounts once plant has 4-6 leaf sets.
Flowering
4-8 weeks (June-August)Small lavender-pink or white flower spikes appear at stem tips; plant reaches 6-12 inches in height.
Flowers are edible and aromatic. For maximum leaf flavor, pinch off flower buds before they open. If allowing flowers, ensure plant gets adequate water.
Peak Growth & Harvesting
Throughout growing seasonPlant is fully established and producing abundant flavorful leaves; compact mounding habit.
Harvest regularly by cutting stems above leaf nodes to encourage branching. Can harvest up to one-third of plant at a time. Harvest in morning after dew dries.
Dormancy
3-4 months (November-March in cold climates)In late fall/winter, foliage dies back; plant goes dormant underground in cold climates.
Reduce watering significantly. In zones 3-5, apply 2-3 inches of mulch for winter protection. Cut back dead stems in spring after new growth appears.

Harvest Tips
Begin harvesting when plant has at least 4-6 sets of leaves (about 6-8 weeks). Pinch or cut stems just above a leaf node; this encourages bushier growth. Best flavor is in mid-morning after dew dries but before heat of day. Harvest regularly to prevent flowering and maximize leaf production. Can be harvested throughout growing season; in cold climates, do major harvest before first frost.
Fun Facts
- 🌱 Nana Alba is a sterile hybrid peppermint cultivar, so it spreads entirely through underground runners (stolons) rather than producing viable seeds, making it easy to propagate by division.
- 🌱 The white variegation on the leaf edges becomes more pronounced and vibrant when the plant receives adequate sunlight; in shade, leaves may revert to solid green.
- 🌱 Despite its compact 'dwarf' size, Nana Alba can spread several feet wide via underground runners if not contained, making it ideal for pots or root barriers in garden beds.
