Bridal wreath spirea grows as a loose, gracefully arching shrub to around 6 ft in height and width. The slender shiny brown stems tend to be a little zig-zaggy.
The leaves are glossy dark green, often turning purplish or reddish orange in autumn. The flowers are snowy white and double, about a third of an inch in diameter and produced all along the stems in open corymbs of 3-6, each cluster about 2.5 in across. Bridal wreath spirea blooms in early to mid spring, before the leaves come out.
Light: Grow bridal wreath spirea in full sun to partial shade. In warm climates, protection from midday sun is helpful.
Moisture: Bridal wreath spirea likes a good moist soil, but of course, not waterlogged.
Hardiness: USDA Zones 5-9. Bridal wreath spirea needs some cold weather to flower properly.
Use bridal wreath spirea in an informal mixed hedge, in the garden border, or as a specimen where its generous springtime bright white floral display will stand out. If left alone, bridal wreath spirea grows into a graceful, open, arching shrub with some branches drooping all the way to the ground. It should never be sheared, but may have to be pruned to keep it in its allotted space. Like other shrubs that bloom in early spring, this one should be pruned (if necessary) right after blooming.
