I have a request of you wonderful folks. my husband (we live in Maine) has recently become interested in growing his own trees. obviously since trees take so long to grow this isn't really for him, but for future generations. He has planted and grown from seed black walnuts, horse chestnut and american chestnuts. he is looking for butternut tree seeds (aka white walnuts)that have fallen to the ground. he will use these to plant seeds and grow new trees. there is a fungus in butternuts that is now killing butternuts throughout much of maine and they are endangered and he hopes to get some that are resistant to the disease. the trees that have this, do not produce seeds. for more information here is a link, it has lots of pictures of the trees and the seeds so you will know if you have one of these or not. http://www.treetopics.com/juglans_cinerea/index.htm I am willing to pay you postage if you are not close by and some for your time to collect these if you have them on your property. I am also willing to swap tree nut from trees we have on our property, currently collected are beech and oak.
