The croton "Petra" is an evergreen shrub-like plant that is boldly marked with bright yellow, orange, red, and even black outlines on multi-colored leaves. They prefer full to partial sun and need bright lighting to produce their boldest colors. It prefers hot, humid weather and grows well outdoors only in Zones 9B-11. Crotons planted outdoors can reach a height of 7-10 feet. Crotons are sensitive to salt spray and must be planted away from saline-prone areas. Grown indoors, they can be maintained to an appropriate height for their setting and container size. Find the sunniest spot in your home with the highest humidity level, and your croton will wow you with its vivid display of variegated leaves.
