Light. Grows in sun or shade. The gold spotting is brightest in good light; in heavy shade the color fades and lower leaves may drop.
Water. Water often while it settles in, but do not keep the soil soggy. Once established it is drought tolerant and can get by on rainfall. Wilting new leaves mean it needs water.
Soil and feeding. It wants fertile, well-drained soil. In a container, use a good Potting Soil that drains well.
Size. Usually 3–6 ft tall. Space plants about 3 ft apart when massing them.
Problems to watch. Usually trouble-free, but mealybugs, scale, spider mites and thrips show up at times. Treat mealybugs and scale with Insecticidal Soap following the label. Hosing off the leaves helps keep spider mites down.
Good to know. The leaves are poisonous if eaten and the sap irritates skin and stains fabric. Wear gloves and keep children and pets away. Frost damages it, but it recovers quickly.
