We have several older (probably close to 100 yr) Maple Trees on my property. The Maple trees are a mix of silver and sugar. We get the twirly seeds in the spring by the bucket full. If you would like to plant your own, let me know and I will send you some of the seeds. The sprouts are quite hardy, I have to pull them out of most everywhere. The local squirrels and chipmonks just love these trees and all the seeds that they drop, I swear theyre feed for months off them.
