Schefflera arboricola: Dwarf Schefflera1
Introduction
This evergreen shrub has attractive dark green, glossy, palmate leaves densely covering flexible, green stems which gently fan out into a rounded crown. Plants are usually seen with multiple stems sprouting from the base. Branching can be encouraged by pinching the stems, which forms a denser shrub. It can be pruned into a small tree over a period of years where it would make an accent or patio tree. The tree remains a green mass, not changing during the year, except when it displays the brilliant orange-yellow fruit in the winter.

Use and Management
A popular house plant, dwarf schefflera performs well in a variety of outdoor settings. It can be used as a hedge, specimen planting, poolside container plant, and even trains well into an espalier on the wall of a building. Aerial roots originate from the lower portions of the trunks and branches, and root into the ground.
Dwarf schefflera is adaptable to sun, part sun or deep shade and does best on light, sandy, well-drained soils. The plant prefers soil which is kept on the dry side. One of the best hedges for shady areas.
There is a cultivar available with variegated foliage.
Propagation is by seed, cuttings, or air-layers.
