Vanhoutte Spiraea is a classic Victorian garden staple, blooming reliably every year is April and May, while adding graceful arching green branches to the landscape in summer. When in bloom in mass, Spiraea x vanhouttei looks like "a cresting wave of white", to quote our sister Louise Gross. Blooming on new growth, Vanhoutte Spiraea performs very well to periodic trimming, and can be used to make a tough but showy hedge, as well as a stand alone specimen. The small leaves are fine textured and very clean. Resulting from a cross between S. trilobata and S. cantoniensis.
