A genus of evergreen trees or shrubs comprising about sixty species, mostly natives of Australia, Asia and South America. They form stately trees of rather formal habit of stem and head, well adapted, under suitable conditions, for making good street trees. The best species for California are Sterculia acerifolia (the Australian Flame tree), Sterculia diversifolia (from Victoria) and Sterculia platanifolia (a native of China). All are fairly vigorous and prefer a warm sheltered situation.

Propagate by cuttings of well-ripened wood placed, in September, in a cool frame and shaded during hot sunshine until rooted, or by seeds sown in Spring. Cover the seeds to the depth of one-eighth of an inch.
