General Distribution: F. nigra is found in temperate deciduous forests of the northeastern United States.
Propagation Goal: Plants
Propagation Method: Seed
Product Type: Container (plug)
Propagule Processing: Seeds exhibit morpho-physiological dormancy.
Pre-Planting Treatments: Seeds are placed in cold moist stratification for 60 to 90 days. Seeds require warm stratification before cold stratification. Germination occurs at 30D/20N C alternating temperature cycle.
