Report an issue with this species
Ulmus pumila, also known as Siberian elm, is a deciduous tree native to Asia. It features dark green, double-serrated leaves and produces unshowy flowers followed by winged samaras. While resistant to Dutch elm disease and drought, it has weak branches, is susceptible to pests, and exhibits invasive root behavior, making it a challenging choice for urban landscapes.
