Propagation Method
Seed collection: Tulip poplar fruit is a cone-shaped aggregate of winged seeds (samaras). Harvest the fruit in the fall after they have turned a light tan and before the seeds separate for dispersal.
Allow fruits to dry for several days and the seeds will easily separate from the fruit by pulling them apart. They can be stored dry for long periods in air tight containers in the refrigerator.
Seed dormancy: Tulip poplar has physiological dormancy.
Seed germination: Stratify seeds using moist chilling for 60-90 days to satisfy physiological dormancy. Following stratification, sow seeds in a nursery container to produce a seedling or sow them in a plastic container in the classroom to observe germination.
