EUCALYPTUS

With few exceptions, these plants are native to Australia. More than 600 different species grow there, ranging from sprawling shrubs (many of them bearing the common name “mallee”) to skyline trees. About 150 species have been grown in areas of California and Arizona that have climates similar to the plants’ native Australian habitats; many more have been grown as solitary representatives in arboretums. Eucalypts are the most widely planted non-native trees in these two Western states—for several hundred miles in parts of California.

Eucalyptus polyanthemos

Hardy to 14°Fto 18°F (–10°C to –8°C). Grows30–75 ft. tall, 15–45 ft. wide, with gray-green, nearly round, 2–3-in. juvenile leaves and dark green, lance-shaped mature leaves. Young leaves useful for fresh and dried arrangements. Select young trees carefully; some have leaves less round and gray than others. Good as specimen or street tree. Can be used as perennial in borderline climates.
