I wondered why some limbs were drooping to the ground. Amur Cork Tree. I only have 4 and would like more. Please tell me all you can about when and how to harvest seeds. Gene

I haven't spent any time collecting seeds of Phellodendron amurense - yet another dioecious species. They appear to ripen in late September into October as well.

If you want MORE plants, contact someone in the mid-Atlantic growing region, where this species is a raging invasive pest plant.

Thanks for all the info. Not invasive here I do not know of anyone around here who has one except me. Gene
