The Princeton American Elm tree is a very fast growing tree. It grows 3 to 6' a year and is very strong. It is not like other fast growing trees that get brittle, it maintains a very strong new growth and is not prone to splitting like some of the Chinese Lacebark elms, Sycamores or Tulip Poplars.
The Princeton American Elm is also extremely urban tolerant. It is the most urban tolerant tree I have ever seen.
