Aronia melanocarpa, commonly known as black chokeberry, is a deciduous shrub native to eastern North America valued for its ornamental white flowers, vibrant fall foliage, and antioxidant-rich berries. Seeds require cold stratification for 120 days to break dormancy, making germination moderately challenging but rewarding. After stratification, seeds typically germinate within 20-60 days when maintained at moderate temperatures with alternating day/night cycles.
Before sowing
Pre-soak seeds for 12-24 hours in room temperature water, then cold stratify for 120 days at 4°C in moist peat.

What to expect
Tips
Soak seeds for 12-24 hours before placing in moist peat for cold stratification. After 120 days at 4°C, sow seeds 1/8 to 1/4 inch deep in well-drained peat/perlite mix. Maintain soil moisture without waterlogging and cover containers with plastic to retain humidity. Keep seedlings at moderate temperatures (20-25°C during day, 18°C at night). Do not discard the seedbed prematurely as germination may be slow and sporadic. Plant in location with indirect sunlight after germination. Seedlings require 2 years in pots before field planting.
