Culture

With good humidity, this plant is easily grown in St. Louis as a houseplant. Use a well-drained humusy potting mixture. Plants need bright light for best leaf color, with some direct sun. May lose lower leaves in too much shade. Plants also prefers high humidity. Consider standing plant on bed of wet pebbles to increase humidity. Water regularly to keep soils moist, but not wet, during the growing season. Does not require winter dormancy, but appreciates a resting period with reduced watering from fall to late winter.

Noteworthy Characteristics

Codiaeum variegatum var. pictum, commonly called croton or Joseph’s coat, is native to Malaysia, Pacific islands and northern Australia. It is a woody-based perennial that typically grows to 6’ tall. In the St. Louis area, it is grown in containers as a 2-4’ tall houseplant. It is noted for its bold, often strikingly foliage. Glossy, leathery, smoothed-edged leaves are in bright colors ranging from yellow, pink, orange, red, bronze, purple and green plus combinations thereof in patterns involving blotching and striping. Leaves are oval to lanceolate (to 18” long). Foliage color is distinctive, appearing somewhat gaudy at times.

Genus name comes from the Latinized version of the Ternate vernacular name, kodiho.

Specific epithet means variegated.

Problems

No serious insect or disease problems. Watch for scale, spider mites and mealybugs.

Garden Uses

Use ‘Mammy’ as a tropical accent in containers and border gardens, but like most crotons, this plant is not hardy in the St. Louis area. Bring this plant indoors before night temperatures reach 50F or use as an annual. Can also be kept indoors year-round, with the best color and overall vigor being achieved with plenty of bright light and even moisture.
