I have 4 acres of woods filled with a lot of birch trees but still I ordered one aspen tree right now because I'm not entirely sure if I have birch or aspen. I'm pretty sure what I have is birch or maybe it's a mix of birch and aspen. I just don't know! Anyway I ordered one aspen and I guess they grow quickly so that is great because on the side of my house I have a crapload of silver maple, elm and buckthorn that I am not too crazy about. I want to chop that all down and lighten it up. Plus I heard that the yellow variety of amanita muscaria like aspen :) so we'll see in 10 years or so if this might be true :) here is a pic of my backyard right now.
