Discover the fascinating Ulmus rubra, commonly known as Slippery Elm or Red Elm, a medium-sized, deciduous marvel native to the central and southern United States. While it thrives in medium moisture, well-drained soils under full sun, this adaptable tree also tolerates both wet and dry sites, making it resilient even in urban environments. Slippery Elm can reach heights of 40-60 feet, with a spread of 30-50 feet and boasts unique botanical features like downy twigs, red-hairy buds, and its signature slimy red inner bark. The tree's reddish-green blooms grace the landscape from March to April.
Historically, the versatile inner bark, rich in mucilage, has been valued for its soothing properties, famously used in throat lozenges and to quench thirst by Native Americans. Despite its coarse texture and susceptibility to diseases like Dutch elm disease, this elm supports wildlife, offering cover and food for birds and mammals. Although rare in commercial nurseries, Slippery Elm remains an essential piece of natural and cultural heritage, lending character and ecological value to diverse landscapes.
