American Elm

Black Gum is a slow-growing ornamental shade tree with a dense pyramidal shape. The foliage is dark green in the summer, and transitions to bright fall colours which include red, orange, purple, and gold. It is commonly used as an ornamental tree in parks and large gardens as a specimen or shade tree.

The small greenish white flowers provide nectar for bees and black tupelo honey is a sought after flavour. The small dark blue fruits which ripen in late summer will attract birds and other animals to your yard. The fruits are edible, but very sour, and are primarily used for pies, flavouring, and drinks. Plant the Black Gum where it will live long-term, as it has a large taproot and does not transplant well.

American Elm is fast growing, tall tree with a recognizable and pleasing shape.

It's well suited for urban environments because of its non-invasive roots and ability to grow on harsh sites (quite salt tolerant). American Elm develops a wide, dense canopy that provides shade for many city streets around North America.
