Spiraea x media
Noted for its massive white dome-shaped blooms up to 6 to 8 inches across and superb autumn color. A snow storm of abundant, massive white flowers covers this plant in April and May. The pure white blooms will light up your garden and contrast wonderfully with the bluish-green foliage. Watch for a blaze of orange and red leaves in fall. The plant is sturdy and holds its blooms up in a neat fashion. Adaptable and easy to grow, this low-maintenance shrub is useful to both the professional landscaper and homeowner. Deer-resistant
Well drained soil is best. Best if pruned after flowering. To promote continued flowering deadhead (remove faded flower clusters.) Medium moisture. Fertilize in early spring by applying a slow release fertilizer specialized for trees & shrubs. Follow
I hate Spireas but this one is really beautiful. I saw it first without flowers and thought the foliage was sublime. The foliage is a lovely soft blue/green, and decently sized leaves (not those puny little spirea leaves) with purple stems. The flowers are very nice, not those hairballs like other spireas. I prune it hard after flowering and it still looks fabulous. I grow it with Thalictrum rochebrunianum which has 8 foot tall pencil thin purple stems.
