Adult leaves are narrow lanceolate or lanceolate, falcate, acute, basally tapered, glossy or semi-glossy, green, thin, concolorous, 7–15 cm long, 0.7–1.5 mm wide.

Eucalyptus radiata essential oil in clear glass vial

E.radiata has six known chemotypes of essential oil. The leaves are distilled for cineole and phellandrene based eucalyptus oils. E.radiata was the first eucalyptus species to be commercially utilized for oil by Melbourne pharmacist, Joseph Bosisto, in 1854 as "Eucalyptus amygdalina".[3]
