What Is Variety Of Elm With Bark That Looks Like Opened Blisters

Question From: W. Proveaux - Essex, Maryland, United States
Q: Is there a variety of Elm tree called "Dreg or Dredge" Elm? It has a distinct bark that looks like blisters that have been broken open - somewhat scale-like.

A: I did a google search but was unable to find this one. I suggest you contact botanical gardens in states that share your zone. If you plan to purchase one, be sure it's listed as resistant to Dutch Elm Disease. Best And Happy Yardening, Nancy
