Showy Mountain Ash

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.

Showy Mountain Ash is a hardy accent tree. It features pretty clusters of white flowers in spring followed by bright scarlet berries lasting into winter.

Great for small landscapes, Showy Mountain Ash is adaptable to both dry and moist locations, and it is suitable for average home landscape conditions.
