Croton "Petra" (Codiaeum variegatum var. pictum "Petra") adds bright color to the garden in the form of long, leathery leaves with splashes of red, orange, pink, yellow and green. Use these evergreen shrubs as hedges, as specimen plants or in shrub borders. They don't need routine pruning, and left to their own devices they grow to a height of 7 to 10 feet with a spread of 4 to 6 feet. "Petra" is hardy in U.S. Department of Agriculture plant hardiness zones 9b through 11.
