Augustine (elm cultivar)

From Wikipedia, the free encyclopedia

The American Elm U. americana cultivar Augustine is a fastigiate tree originally selected in Bloomington, Illinois, in 1927. Distinguished by its thicker branches and larger, more deeply-toothed leaves, it has proven particularly susceptible to Dutch elm disease, exhibiting 36 % crown dieback in one year after inoculation with the disease's causal fungus.
