Type
Shrub
Family
Rosaceae

Sorbaria sorbifolia 'Sem' is a highly decorative suckering shrub, prized for its feathery, fern-like foliage, which emerges coppery pink in spring, turns light green in summer, then takes on reddish-orange hues in autumn. It forms a dense, rounded bush, slowly spreading by its shallow roots. In summer, it produces upright panicles of creamy white flowers, slightly fragrant and highly visited by pollinators. Tolerant of intense cold, poor soils, and difficult conditions, 'Sem' is ideal for naturalized areas, embankments, informal borders, or country-style mass plantings. It is appreciated as much for its ecological versatility as for its evolving visual interest over three seasons.
