Report an issue with this species
Eucommia ulmoides is a small tree native to China, valued for its dense, low-branching canopy and shiny, broad, dark green foliage. It is considered vulnerable in the wild but tolerates urban environments well. Its leaves and bark produce a stringy latex-like sap when damaged, and it attracts birds.
