Schefflera, Schefflera actinophylla

Schefflera is an ideal tree if you are looking for a quick tropical effect.  It grows from multiple trunks up to large "umbrella" leaf whorls.   The soft wood grows very fast, so often, annual pruning is necessary to keep it within bounds. 
Schefflera trees can grow quite large if allowed.  A decent frost will reduce the tree if you do not.  They are cold sensitive.
