Establishment
First 3-6 monthsYoung plant with minimal branching; foliage shows bronzy-red new growth with some green adult foliage mixed in.
Water regularly to keep soil moist. Apply 2-3 inches of mulch around base. Avoid heavy pruning. Shelter from harsh winter winds in zone 6.
Vegetative Growth
Spring through summer, 4-5 monthsPlant develops fuller branching structure with predominantly green summer foliage. New tips remain reddish.
Continue regular watering. Light fertilizing in early spring with balanced fertilizer. Prune only to shape if needed after blooming.
Flowering
Late spring, 2-4 weeksDelicate clusters of small white flowers appear at branch tips. Foliage may show bronze tones as temperatures cool.
Do not prune during flowering to avoid removing future berries. Maintain consistent moisture. Light feeding optional.
Berry Development & Fall Color
Late summer through winter, 4-6 monthsFlowers fade and bright red berries develop. Foliage intensifies to vibrant crimson, burgundy, and purple tones as temperatures drop.
Reduce watering slightly as growth slows. Do not deadhead berries; they persist into winter and feed birds. Foliage color peaks mid-fall through winter.
Winter Dormancy & Rest
December-February, 2-3 monthsPlant enters semi-dormancy with deepest purple-red foliage color. Berries persist on branches. Minimal active growth.

Fun Facts
- 🌱 Nandina Nana Purpurea's dramatic color change is triggered by cooler fall temperatures and shorter day length, displaying some of the most intense purple-red tones of any compact shrub—deeper and longer-lasting than many dwarf Japanese maples.
- 🌱 The name 'Nandina' comes from the Japanese 'Nanten,' meaning 'southern bamboo,' though it is not actually a bamboo at all but belongs to the Berberidaceae family, making it a unique ornamental with bamboo-like foliage.
- 🌱 Unlike many ornamental shrubs, mature Nandina Nana Purpurea can spread via underground rhizomes, though the compact cultivar is far less aggressive than standard Nandina domestica and is rarely invasive in cooler climates.
