What common name is associated with Nyssa sylvatica?

Nyssa sylvatica is commonly known as sourgum, or black gum. This deciduous tree is recognized for its distinctive glossy leaves and beautiful fall colors, often exhibiting shades of yellow, orange, and red. The name "sourgum" reflects the flavor of the tree's fruit, which is a bit acidic or sour in taste, making it less desirable for consumption but still attractive to a variety of wildlife.

The other options, such as quaking aspen, callery pear, and scarlet oak, refer to different species with unique characteristics and are not associated with Nyssa sylvatica. Quaking aspen (Populus tremuloides) is known for its beautiful white bark and trembling leaves; callery pear (Pyrus calleryana) is recognized for its ornamental flowers; while scarlet oak (Quercus coccinea) is notable for its lobed leaves and vibrant fall coloration. Each of these has distinct growth habits and environmental preferences that differ significantly from those of sourgum.
