I am researching an upright ginkgo and have run into Elmwood Pillar and Elmwood Upright. I am wondering if these are one and the same and if not, what is the difference? It sounds like Elmwood Upright might be a newer cultivar, if so, is it improved? I noticed a great picture of Elmwood Pillar on this site, that's what got me wondering. Thanks.
