DESCRIPTION
Firestorm Chinese Croton is an evergreen shrub that averages 3 to 5 feet in height with a comparable spread. It can be dense if properly pruned and it is upright to spreading in form. The somewhat cascading branches work well in hanging baskets. It has a slow to moderate growth rate.
Leaves are evergreen, lanceolate in shape, simple, opposite in arrangement with somewhat wavy margins, shiny, and 3 to 5 inches long. The top of the leaf is variegated in color with medium green, cream, and touches of pink. The bottom of the leaf is maroon. New leaves are a deep red/maroon. As with many plants in the Euphorbia family, Chinese Crotons have a very milky sap.
Flowers are inconspicuous, dioecious, small, greenish-white in color, and are borne in axillary and terminal racemes. Spring to fall is the usual bloom time.
Fruit are red, fleshy, 3-lobed capsules containing ovate-shaped, smooth seeds.
HARDINESS
Hardy in USDA Zones 10 to 11, down to about 30 degrees F.
LIGHT
Full sun in the morning with some afternoon shade; part shade
SALT
Poor Salt Spray Tolerance – it’s risky for this plant to be put in a coastal area as it has minimal tolerance. It would require multiple layers of protection such as in a greenhouse, indoors, or in a small enclosed area such as a courtyard beyond the dunes.
SOIL
It prefers a rich, moist, well-drained soil, but it will grow on other well-drained soils.
WATERING
Once established, it has moderate drought tolerance, but it will be much healthier with irrigation in dry spells. Indoors, let the soil dry slightly between waterings.
FERTILIZER
It has no unusual needs. In general, apply a slow release balanced analysis during the growing season and lower nitrogen as winter approaches. Specifics depend on the nutrient holding capacity of the soil, the soil’s pH and a soil test if possible. Follow the fertilizer product label suggestions unless a soil test suggests something different.
PROPAGATION
Cuttings; air layering
PRUNING
Prune selectively to encourage branching.
