At one time, this was the preeminent street tree in the US, due to it's beautiful vase shape, but disappeared due to the intruduced Dutch Elm disease. Ulmus americana 'Princeton' was originally selected in 1922 by New Jersey nurseryman William Flemer for its aesthetic merit. By coincidence, 'Princeton' was later found to have a moderate resistance to Dutch elm disease in the USA. It is also very resistant to the elm leaf beetle, which is the carrier of Dutch Elm Disease.

Adaptable to a wide variety of soil conditions. American elms tolerate deicing salts, drought, poor soil conditions, air pollution and range of pH¹s. Prune to establish central leader.

Over the past 50 years, millions of stately elms shading the streets of the American landscape have been lost to Dutch elm disease (DED). 'Princeton' has good levels of disease tolerance, although no cultivars are totally immune to DED. Both cultivars ('Valley Forge' and 'Princeton') possess the "classic" American elm shape and the tolerance to air pollution and poor soil conditions of the species. Examples of 'Princeton' were planted along Washington Road and another road in Princeton and most of these trees survive to this day unaffected by disease (Wikipedia). The cultivar was more recently chosen to replace elms killed by disease along Pennsylvania Avenue in front of the White House.

Plant history. Plant a disease-tolerant American elm!
