Finding and Germinating Japanese Maple Seeds

Japanese maples have tiny, inconspicuous spring flowers that develop into miniature winged seeds ("helicopters"). See flower photo and seed photos.

Cuttings rarely root; most cultivars won't root at all.
Grafting is standard commercially.
Seeds: stratify 60–90 days at 40°F (damp paper towel in fridge). Plant ½ inch deep, keep warm. Germination sporadic.
Seedlings won't replicate hybrid parents but can be attractive.

Use lots of seeds; grow under lights, harden off, plant with afternoon shade.
