The American black elderberry (Sambucus canadensis), for instance, often forms dense thickets through its suckering habit, creating a valuable habitat for wildlife. It is a member of the Adoxaceae family (also known as the moschatel family), which includes small to large shrubs and a few small trees. However, it is characterized by weak stems that arise from the crown of the plant. Elderberry shrubs typically have multiple branches that grow from the ground, in contrast to single-stemmed trees, giving them a bushy, woody appearance.

To determine if elderberry is a bush or tree, examine its growth pattern and physical characteristics:

• Leaves are oppositely arranged with a compound structure of 5 to 9 leaflets, measuring 15 to 30.5 cm (6 to 12 in) long.
• Elderberry leaves are opposite and pinnately compound, measuring 15 to 30.5 cm (6 to 12 in) long.
• Height can vary significantly, from a modest 2 meters to an impressive 4 meters. Elderberries can sometimes be classified as a small tree, especially when they reach greater heights and develop a more tree-like form.
• Older stems provide structural support to the plant.

Deciduous Shrubs vs. Small Trees

Most elderberries typically grow as deciduous shrubs, reaching 2 to 4 meters (6.5 to 13 feet). Some varieties can grow quite tall, reaching up to 20 feet in optimal conditions. They are known for their pinnate leaves and ability to form dense thickets through suckering, enhancing their aesthetic appeal and providing essential wildlife habitat. Elderberry typically prefers moist, edge habitats in full or light shade, making it a versatile choice for various landscapes. They are often found in moist locations such as lake and pond shores, low areas along roadways, and in low forests and old fields. The elderberry plant is native across the U.S. except in Nevada, Utah, Idaho, Oregon, Washington, Alaska, and Hawai’i.

Under certain conditions and depending on the species, elderberries can also grow as small trees. These trees often have an upright growth habit with fewer suckers, making them a striking addition to landscapes.

Whether as shrubs or small trees, elderberries add beauty and ecological benefits to gardens and natural areas, including shrub varieties.
