Hummingbird Bush

A friend gave me this pretty bush which has clusters of white flowers and very green shiny leaves.  She said its name was hummingbird bush.

 Much to my surprise my shrub book shows a red-flowering bush quite unlike my small shrub and calls it a hummingbird bird bush.  I am still searching for a reference and perhaps another name.

Meanwhile it has been blooming this July.  It will die back for the winter very late.  It is somewhat hardy.

Incidentally, it produces many small offspring by sending out roots--plenty to share but not enough to be annoying.
