Outside of the nerdy members of the International Oak Society, few gardeners have ever heard of Quercus x vilmoriniana. This spectacular oak is a hybrid between the Asian Quercus dentata and the European Quercus petraea. Quercus x vilmoriniana has been known in European gardens since 1894, but is rarely seen in US gardens. The hybrid is named for the late French botanist Maurice Leveque de Vilmorin.
Our 20′ tall specimen at JLBG was planted in 2012 and has developed not only superb foliage, but splendid deeply-fissured bark. There is an old specimen at Cornell in NY, so it shows good cold tolerance in addition to loving our hot, sweaty summers. We have sown acorns from our plant, and if they grow, we will make this available though the Southeastern Plant Symposium Rare Plant Auction in June.
