Bridal wreath spirea is a medium-sized, fast-growing deciduous shrub with an upright arching habit featuring cascading waterfalls of white double flowers. The flowers are followed by 1- to 3-inch-long oval green leaves, which transition to attractive yellow-orange or purplish-brown hues in the fall.

Bridal wreath spirea grows best in full sun, well-draining loamy or acidic soils, withstanding wintery weather and summer temperatures.
