Did you know?

What tree has been attacked by a disease from another country?

Although once widely planted as a street and lawn tree, American Elm trees have been  decimated by Dutch Elm (fungal) disease. The tree is no longer considered to be a good  selection for landscape uses.

Are there new forms (cultivars) of this tree being raised in university nurseries?

Disease resistant varieties such as Ulmus americana ‘Valley Forge’ are promising.  However, the trees are not totally immune from the disease.
