Schefflera actinophylla: Schefflera1
The large, palmately compound, shiny leaves sit atop the multiple, thin, bare trunks of schefflera, creating much the impression of an exotic, 25-foot tall plant-umbrella. Schefflera lends a tropical effect to any landscape use, from patio containers to interiorscapes to protected outdoor locations. Capable of reaching 40 feet in height, schefflera will grow rapidly to create a dense windbreak or screen for property lines. When grown in full sun, trees will produce flowers during the summer, an unusual arrangement of small blooms on three-foot-diameter, stiff terminal clusters. These clusters are held above the foliage and are arranged like the ribs of an inverted umbrella, or like the tentacles of an octopus. The red blooms are followed by reddish-purple, half-inch fruits.

Use and Management
Schefflera will grow in full sun or partial shade on a wide variety of well-drained soils but require full sun to flower. Trees will display their best growth on rich, moist soil in a full sun location. There is significant leaf drop on this easily-grown tree creating quite a racking job, but plants will require very little pruning if given enough overhead space to develop. Trees may be topped as desired to create multi-level masses of foliage. This may be desirable since the lower portions of the trunks lose all their foliage over time. Sometimes the tree is used as a house plant, but it is too often misused by planting it too close to a building.
It has naturalized in some parts of south Florida and has been placed on a list of exotic pest plants.
Propagation is by seeds, cuttings, or layers.
Pests and Diseases
No pests or diseases of major concern. Scales and sooty mold are a minor problem. Trees used indoors are susceptible to infestations of spider mites.
