Germinating Princess Tree (Paulownia) Seeds After Winter Collection

Princess tree seeds collected in winter may have reduced viability due to moisture exposure, but many will still germinate after proper stratification.

Recommended Protocol

Air-dry seeds for 1 week.
Place in a sealed container with moist peat moss in the refrigerator for 3 months (cold stratification).
Sow in pots with potting mix; cover with plastic film to create a mini-greenhouse.
Keep at 70–75°F; remove plastic once germination occurs.

Tree seeds often have long dormancy periods; patience and proper stratification are key.
