Outstanding Qualities

This small deciduous shrub is easy to grow and has a compact attractive habit. In late spring to early summer its tight mounded foliage is dotted with flat clusters of white flowers. The tiny birch-like leaves are deep green with an almost iridescent sheen framing its bright blooms. In autumn, leaf shades of orange, red and purple add sparkle to the end of the season. Use it as a single specimen mixed among perennials or in drifts to edge shrub beds. The deep green leaves and white flowers on this compact plant create a lovely contrast to taller ornamental grasses, like Miscanthus sinensis 'Morning Light' or to the soft flowing seed heads of Molinia caerulea, purple moor grass.

Culture Notes
This small spirea prefers full sun to light or open shade. Plant it in rich, well-drained soil, although it will tolerate clay if the drainage is adequate. Provide regular water to this small shrub to keep it looking its best through the summer. A few older stems can be pruned to the ground in the winter every year. Alternatively, cut the entire shrub back to six to eight inches tall every three or four years and allow it to regrow
