As with all spiraea, it is a dense, compact, deciduous flowering shrub with outward arching branches. This particular cultivar is noted for its early blossoms, producing fragrant white flowers in early spring along slender naked branches. The foliage of narrow, green, leaves is dense on the branches, but appears after the blooms. This plant works well on banks, as a low mass or filler, or as the front of a shrub border.
