Leaves: The small alternate leaves are simple, toothed, and often diamond-shaped.
Flowers: Dense clusters of small pure-white flowers line the branches and create a foamy, fountain-like display.
Flowering time: It flowers in spring on growth made the previous year.
Fruit: The small brown dry fruits are not showy.

Look-alikes

Bridalwreath SpireaSpiraea prunifolia

The commonly planted Bridalwreath Spirea has double white flowers that open before the leaves. Bridal Wreath has rounder flower clusters along leafy stems, although its double-flowered can still be confusing.

Why they get mixed upBoth are arching spring shrubs sold under a bridal-wreath name.

Vanhoutte SpireaSpiraea × vanhouttei

Vanhoutte Spirea often has broader leaves with shallow lobes near the tip; Bridal Wreath usually has narrower, more diamond-shaped leaves. Flowers alone may look alike.

Why they get mixed upBoth have arching branches covered with round white flower clusters.
