Slippery elm is a medium tree with rough, sandpapery leaves and inner bark that becomes mucilaginous when chewed or soaked. The bark is dark brown and often furrowed.
Habitat and range
In Maryland, slippery elm grows in rich, moist woods, along streams, and on slopes, often with other hardwoods. It is less common than American elm was and has also been affected by Dutch elm disease.
Uses and significance
The inner bark was traditionally used for throat remedies and poultices. The wood is used for boxes, furniture, and lumber. Slippery elm provides food and cover for wildlife and is a component of mesic forest ecosystems.
