Ironwood Tree
Discovery Japanese Elm

Ironwood Tree is one of the strongest and most resilient trees you will find in North America. In fact, it has the hardest and most dense wood of any North American tree. Prized for its oval shaped canopy and showy winter trunk, this striking shade tree will make a beautiful addition to any yard. Make sure you do not plant near roads as it is highly salt sensitive.

Discovery Japanese Elm is great for anyone who doesn't have a lot of time to maintain their trees as it doesn't drop many seeds. It has beautiful dark green foliage and is resistant to Dutch Elm Disease. This elm is similar in shape to the American Elm but is roughly 30% smaller. Instead of having an irregular and broad-shaped crown as other Japanese Elms do, the Discovery Japenses Elm has symmetrical branching, an upright growth form, and develops a classic vase-like crown.
