If you want to wait another month or so I could help. I have a trident maple in my yard that throws out so many seeds I have trouble collecting them all and throwing them out and usually have to pull at least around 50 seedling each year as well. If you would like you can send me a private message in late May or June and I can send you some. I would just ask you send me a self addressed envelope with postage paid and I can pretty much give you any quantity you want, reasonably.
