She-Oak (Casuarina)
She-Oak Genus Details
Australian pine is fast-growing; it can grow 60 feet tall in 6 years with a weeping growth habit. Several tree and shrub species have been planted in southern Florida and California as shade trees, hedges, ornamental plants, or windbreaks. The tree form has naturalized in some areas and forced out native vegetation. Australian pines have very reduced flowers, and the silver-grey needle-like branches. These brances have leaves that are reduced to scales that superfically resemble pines. The flowers are wind-pollinated and shed large amounts of pollen in spring and autumn, depending on the species and annual variation. The tree forms flowers in late summer in the southern Florida area where it has been reported to cause pollinosis.
