We've been processing lots of hardy morus alba seed here. Seed is collected from a highly productive dark fruited variety in Ithaca, NY. Several male trees surround our mother tree, resulting in a very high germination rate. Packet of 100+ seed for $10. Plant them now for a small 6-12" seedling, or plant them early next spring for a larger tree.
We also will be collecting juneberry seed and have lots of other tree seeds available. Tree Seeds Thanks for looking,
