With rounded or heart-shaped, silver-gray leaves, the silver dollar plant (Eucalyptus cinerea) makes a striking visual statement in your garden, whether you grow it as an annual 6-foot bushy shrub from seed or as a 60-foot-tall tree. It's native to southeast Australia and thrives in U.S. Department of Agriculture plant hardiness zones 8 through 11. The plant does best when planted in well-draining soil and in full sun where it can get at least six hours of direct sunlight each day.
Invasive in Florida.
