Chionanthus virginicus

Over the past five years, American fringe trees have faced attacks by the emerald ash borer, Agrilus planipennis. While this is certainly a concern, an ongoing study by Wright State University gives hope that Chionanthus might fare better than ash trees in terms of susceptibility to the beetle. There is evidence that ornamental plantings are not targeted like dense wild populations of fringe trees. Also, trees that are healthy and well cared for are much less likely to be infested.

C. virginicus thrives in rich, moist woods and hillsides. There are numerous specimens at Thomas Jefferson’s home at Monticello, and it was apparently one of his favorite trees. In the landscape, they do best in full sun to partial shade and they love heat and humidity. They are best grown as a multi-stemmed tree or large shrub and will reach a final height of 20 feet with a canopy spread of 15-20 feet. Chionanthus seldom need pruning and are naturally somewhat slow growing. They do well in urban settings, although perhaps not as a street tree. I say this for two reasons. First, they will not tolerate prolonged drought. Secondly, they are so beautiful while in bloom, I fear they would distract drivers. I can literally see myself trying to take a drive-by video or selfie and ending up in the ditch — or worse. Anyway, you’ve been warned. Seriously though, Chionanthus are beautiful trees, and I wish they were more available to American gardeners.
