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.
