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 Bladdernut is a fast-growing, ornamental shrub native to eastern North America. It can be grown as a large shrub or trained as a small tree. The small, drooping, white flowers are bell-shaped and grow in clusters. They appear in mid to late spring, attracting various pollinators. Well suited as an understory plant as it prefers shady and partial sun location with moist soils.

The blossoms mature into papery seed capsules and have been described as miniature Japanese lanterns. They are commonly used in dried flower arrangements. The seeds found within the pods are edible, and have a taste similar to pistachios. They can be eaten raw, used in baking or made into a sweet cooking oil.

Care should be taken when planting American Bladdernut, as it can spread quickly. It is prone to suckering and will self-seed. Plant the right tree in the right place.
