Bridal Wreath Spirea (Spiraea prunifolia) is a large, arching shrub with long branches covered with white flowers in the spring. Most established spirea plants are drought tolerant. It loves full sun but can tolerate some shade.
It blooms at the same time as peonies and bearded irises. The plant needs good drainage and should be pruned after blooming to remove old dead canes and to shape if necessary. Pests and diseases do not usually bother this great old-fashioned plant.
