Gardeners' Notes:


On Mar 26, 2015, coriaceous from ROSLINDALE, MA wrote:

This is the most commonly planted American elm cultivar today.

There are now a few cultivars with proven tolerance for Dutch Elm Disease. Controlled testing shows this is one. It also shows resistance to elm leaf beetle.

Classic American elm vase-shaped habit.

Suitable for specimen use where there's enough space. Space at least 50' apart. Mature height is 60-80' or greater.

Pest and disease issues suggest that the mass planting of a single cultivar is inadvisable.

We bought two 3ft tall 1/2 inch diameter trees in spring 2002. One of them has gone crazy and is now 35 ft or so and the trunk is nearly 9 inches in diameter. The other one is about 25 ft tall and 6 inches in diameter. They were $50 apiece in 2002 and I consider them one of our better investments. They are planted about 65 feet apart in our front yard to someday (sooner than later I expect) provide the beautiful cathedral-like arched canopy only an American Elm can provide. My folks planted one in Hinsdale, Illinois in 1954 and that plant is still alive and thriving- you just can't beat some memories.

My tree is growing fast like what we expect from an american elm. Only problem is that they cost alot. Bring the glory back to the countryside, plant an DED-resistant american elm.

This is a variety of the true elm, Ulmus americana, not a hybrid. Supposedly this elm has shown high resistance to the Dutch Elm Disease fungus.
