Mirror plant (Coprosma repens) is an evergreen shrub suitable for growing in USDA plant hardiness zones 8 through 11. This fast-growing shrub can reach mature heights of 10 feet fairly quickly. Mirror bush plant is available in several variegated forms and various combinations of creamy white, lime green, bright pink, purple, gold or soft yellow. The colors intensify when cooler weather arrives in autumn. Dwarf varieties, which top out at 2 to 3 feet, are also available. Look for clusters of inconspicuous white or greenish-white blooms followed in summer or fall by fleshy fruit that turns from shiny green to bright red or orange.
