- Description
-
Water tupelo, is a native, large, long-lived deciduous tree in the Nyssaceae family inhabiting deep rivers or coastal swamps in the Southeastern United States that are usually flooded most of the year. It has a swollen base, large hanging fruit, and brittle twigs that distinguish it from the Blackgum. Water Tupelo has a long, straight trunk, narrow, open crown of spreading branches, and large, shiny leaves. In a forested stand, the trunk is often long, but somewhat crooked, above its buttressed base. It is very symmetrical and pyramid-shaped in its early years but develops an irregular form with age.
It grows well in medium to wet soils in full sun to part shade and prefers moist, acidic soils. It tolerates poorly-drained soils and can grow in standing water. A long taproot makes it difficult to transplant. It is rarely used in the home landscape. Often reaching heights of 100' with a trunk diameter of 3 to 4 feet, it is mostly dioecious and male plants are helpful to get a female fruit set. This plant has a beautiful yellow fall color and is heat tolerant.
Insects, Diseases, and Other Plant Problems: Fire is a major enemy of Water Tupelo. It scorches the thin bark, allowing the entrance of rot-causing fungi. The forest tent caterpillar (Malacosoma disstria) is a serious enemy in some years and locations.
