What berries grow in crimson towers,
With tangy taste that puckers and sours?
Staghorn sumac! (Rhus typhina)
Growing up, the slim outline of the staghorn sumac lined the perimeter of my backyard, reaching out its limbs, dotted with dark red berries. In the bored heat of summer, my brothers and I would grab the plant’s thin trunk and shake, raining berries down on us and gathering as many in our hands and pockets as we could.
These wide and angular branches give the staghorn sumac its name, resembling the sharp antlers of a deer. And much like the thin, soft velvet that covers young antlers, the staghorn sumac’s stem is lined with a fine velvety layer of hair (or trichomes). In addition to serving as a protective layer from insects and the elements, this fuzz distinguishes the staghorn sumac from its common relative, the smooth sumac. These two plants share quite a few traits, both having pinnate (feather-like leaves) and producing red fruit. However, the smooth sumac, as the name suggests, lacks the fine velvety texture on its stems that characterizes the staghorn.
Planting roots
Beyond its striking leaves and vibrant berries, the staghorn sumac has a unique way of multiplying and thriving in the wild.
Growing from a large shrub to a small tree, the staghorn sumac ranges in size from about 3 to 30 feet in height. It is native to the eastern half of the United States and flourishes on the edges of forests, clearings, and dry, rocky, or gravelly soils.
The staghorn is a colony forming plant, meaning that they cluster in groups of genetically identical clones, connected through an underground network of roots. The plant reproduces new clones via a process known as root suckering, where vertical growths originate from its root system. In addition to producing colonies, the staghorn sumac also naturalizes through self seeding, the dispersal of its own seeds.
The flowers of a staghorn sumac are crimson, hairy, and bloom through May to July. Berries form tightly pyramidal clusters and are usually ripe by September, persisting into the winter, even after the staghorn sumac has lost its leaves, though this timeline can vary by geography.
The staghorn sumac is dioecious, male staghorn sumac and female staghorn sumac flower separately. The female staghorn sumac produces flowers and seed, while the male staghorn sumac only produces flowers. Due to the staghorn sumac’s colony forming habits we just learned about, and while not always the case, groves of predominantly female-only or male-only trees can be found. The colony of staghorn sumacs that grew around my childhood backyard were all seed bearing, and therefore a colony of female-only sumacs.
Berries and Beyond
The berries produced by the female staghorn sumac hold the same shade of deep red as the flowers, but also have finer hairs and a denser, round body. As children, my brothers and I were convinced that these velvety, red berries were poisonous, and we handled them with a slight air of suspicion. However, despite their vibrant color, the berries lining our pockets were not poisonous. While brightly colored fruits may have a reputation for being dangerous, many use bright colors to attract different pollinators. In this case, the bright Staghorn sumac berries are an edible fruit that has been used by humans for centuries. They are high in vitamin c and have a strong, tart taste. Upland game birds, songbirds, white-tailed deer, and moose also eat the tree’s leaves and twigs, while rabbits eat even the plant’s bark.
The staghorn sumac has been utilized by Indigenous peoples in North America for a variety of different purposes—including traditional medicine—over hundreds of years. The fresh twigs of the staghorn sumac, once peeled, can be eaten, and have been used in dishes such as salads. These same twigs, along with the leaves, can be brewed into medicinal tea, traditionally used to relieve post pregnancy bleeding, alleviate respiratory conditions such as asthma, and assist in digestion. In addition, the roots of the staghorn sumac have historically been used for their supposed antiseptic and anti-inflammatory properties.
A common use for sumac berries is to make sumac-aide, a lemonade-like beverage with a strong, tart taste. Sumac-aide has been used for its believed medicinal properties, or simply as a refreshing summer drink. Sumac berries are ready to be harvested and used for culinary purposes during late summer, once they turn dark red in color.
The staghorn sumac trees that once grew lush in my childhood backyard are all gone now, leaving an empty patch of dirt in their wake. Although my family does not understand the events that lead to their demise completely, potential disease could be one contributing factor. The staghorn sumac is a resilient tree that is able to flourish under a variety of conditions. However, like all plants, the staghorn sumac is still susceptible to disease. Fungal diseases such as anthracnose, powdery mildew, and root rot, and bacterial diseases such as leaf spot can infect and kill groves of the staghorn sumac. In addition, invasive pests such as Japanese beetles can strip the staghorn sumac by skeletonizing its leaves and damaging flowers.
Recently, I was walking along an icy boardwalk near my childhood home and noticed little fuzzy flowers, bright red against the white snow. It took me a closer inspection of these cute crimson flowers to notice the large group of staghorn sumac arching above the boardwalk and over my head. The trees bore their rich red flowers despite the other snow encrusted barren trees of the landscape.
If you know where to look, the staghorn sumac is everywhere, dotting the sides of highways, bike paths, playgrounds, and perhaps even your own backyard.
