Black Tupelo, scientifically known as Nyssa sylvatica, is a type of hardwood native to the eastern United States. Also known as black gum or sour gum, it’s valued for its durability and unique aesthetic qualities. Although not commonly harvested for lumber due to its tendency to warp, it still finds uses in specialty applications.
Aesthetically, Black Tupelo wood has some interesting attributes. The heartwood is usually pale yellow to light brown, with occasional streaks of darker brown, while the sapwood is typically a lighter color. The grain is generally interlocked, and the texture is medium to coarse, creating a unique, somewhat rugged appearance. The wood can also display an attractive figure, especially on quartersawn surfaces.
When it comes to workability, Black Tupelo presents a challenge due to its interlocked grain, which can cause tear-out during machining processes. However, it glues, stains, and finishes well, and it can be a good choice for certain applications when care is taken during the working process. Its natural durability makes it resistant to decay, and it is known for its exceptional resistance to wear, which can make it suitable for applications such as flooring. It’s also used for utility purposes, tool handles, pallets, and veneer. As always, it’s advisable to consult with a local lumber supplier for specifics when considering using Black Tupelo for your projects, as characteristics can vary.
