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.

Eucalypts are the most widely planted non-native trees in these two Western states—for several hundred miles in parts of California.Eucalyptus sideroxylon
