In 2013 I bought some fastigiate oaks from Musser Forests (http://www.musserforests.com/). Fastigiate is from Latin and means narrowing toward the top and when applied to trees, having upright usually clustered branches. Trees that have a more narrow form are often called fastigiate and these oaks are actually named Quercus robur ‘Fastigiata’. The English oak is a pretty tree, especially when it gets large, but it can be a bit much for a suburban garden, needing a huge space to be grown to full advantage. These narrow trees, however, should do reasonably well here. They are not quite as hardy as the species but I’ve seen them growing in the district and there is a huge one only a few blocks away, so I’m hopeful. I have them growing in two parts of the yard, one on the north end of the yard and one along the back (west side). Planted in 2013, they are already more than 10 feet tall, and growing quite quickly.
