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. Kay
Based on a really quick Google search (ginkgo genetic diversity), there is significant diversity in remaining wild populations. So there's a chance that cultivars might come from a variety of genotypes. I'd wondered whether all the ginkgoes in North America were descended from a few handfuls of seed from just a few trees. Looks as though a few nurseries, at least are indeed offering 'Elmwood upright' as different from 'Elmwood'. This cultivar list seems likely to be reasonably complete. It just has 'Elmwood' as a name. Now for someone who knows ginkgoes to explain. Anyway, it looks as though there's plenty of tall, skinny ginkgoes for narrow spots.
