Plant Profile: Fraxinus caroliniana

Fraxinus caroliniana, commonly known as Carolina Water Ash, is a relatively small, long-lived deciduous tree or shrub indigenous to the southeastern United States. This species often features a swollen base and a leaning posture, topped with a rounded or narrow crown. It thrives exclusively in the deeper swamps and along the riverbanks of the Carolina coastal plains and Piedmont regions, although a few specimens have been identified in Wake and Anson counties. Typically, this tree reaches a height of about 25 feet and has a trunk diameter ranging from 6 to 8 inches. It is sensitive to salt spray and brackish water, preferring to grow as an understory tree in moist to wet, shaded environments with acidic soil.

The foliage of the Carolina Water Ash is quite distinctive, characterized by its relatively large, pinnately compound leaves. The tree also produces winged seed pods that dangle in clusters, adding to its visual appeal. This species is well-suited for wet areas in gardens, such as locations with frequent standing water, pond edges, boggy spots, or low-lying regions.

**Diseases, Insects, and Other Plant Issues:**

This tree is vulnerable to the Emerald Ash Borer (Agrilus planipennis), a highly destructive wood-boring beetle that originated in Asia. First identified in North America in July 2002, this pest has since established itself in states like Michigan, New York, Ohio, and in Ontario, Canada, leading to the death of millions of ash trees across the northeastern United States.
