What is this bush?


I would like to identify


Thank you for contacting the Toronto Master Gardeners.

Your photo shows a beautiful example of a Deutzia gracilis.  This shrub grows best in average, medium moisture well-drained soil in either full sun or part shade.

I have attached a link below which will give you more information on this lovely flowering addition to any garden.
