Spiraea prunifolia 5-9' x 6-8' Also called Shoe Button Spirea or Popcorn.
This spirea looks like it came right out of grandma’s side yard with its bright masses of double flowers that look like miniature white roses on long arching bare branches in early spring. Large graceful classic old-fashioned coarse open-vase habit.
Some branch tips will touch the ground, so give it some room to express itself. Deep blue-green foliage emerges after the flowers blossom.
Requires very little pruning although older plants can be rejuvenated by cutting to the ground following bloom. Like other spring-flowering shrubs, prune after it’s finished flowering.
Prefers full sun to partial shade, moist but well-drained soils. Not to be confused with Vanhoutte Spirea (Spirea x vanhouttei) also called Bridalwreath, which has clusters of single flowers on leafy branches. Native to eastern Asia. Z4. (1-3' bare-root plants)
