3 out of 5 stars
A fast growing tree with an upright, rounded to irregularly-shaped habit. The aromatic, 2 to 3 inch, gray-green to blue-green leaves have a rounded to oval shape when young, becoming more ovate to broadly lance-shaped in maturity. The young leaves are often used in dried and fresh flower arrangements. Small cream-colored flowers and woody seed capsules are unremarkable. The pale smooth juvenile bark eventually gives way to rough, slightly shaggy-looking mature bark. The species is noted for its drought tolerance. More cold hardy then some other Eucalyptus trees. Responds well to pruning. May become chlorotic in our heavy soils or if chronically overwatered.
