Black Gum
American Plum

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 Plum is a cold-hardy wild plum native to North America that grows as a small tree or large multi-stemmed shrub. Small, firm, red plums ripen from mid to late summer; the skin is tough and tart, whereas the flesh is sweet and juicy. While some enjoy eating them fresh, they are more commonly used for baking and preserves. It is considered a universal pollinizer for other plum varieties and is often used for grafting or as a rootstock.

In spring, American Plum produces abundant white to pink flowers that attract a variety of pollinators, providing an important early-season source of nectar and pollen. It also serves as a host plant for numerous moth and butterfly species. In its native range, it is recognized as an important keystone plant, as it has a disproportionately large impact on local ecosystems.

American Plum tolerates a wide range of soil conditions, from acidic to alkaline, and heavy clay. It is well suited to a variety of projects, including fruit orchards for cross-pollination, as well as pollinator plantings, naturalization, and restoration projects.
