Report an issue with this species
This small to slender tree, also known as illyarrie or red-cap gum, features a sprawling canopy with aromatic, dark green leaves. It is notable for its spectacular, showy sulfur-yellow blooms with bright red caps, followed by large, bell-like fruits. Eucalyptus erythrocorys makes an excellent urban and street tree due to its drought and salinity tolerance and shallow root system.
