The genus Angophora is very close to Eucalyptus, and can be distinguished easily by its opposite leaves. The old bark is shed in spring in large flakes with the new salmon-pink bark turning to pale grey before the next shedding. The tree has a handsome, rugged ornamental appearance and its young red tips are often used in floral arrangements.
