10 Seeds False Spirea Shrub Sorbaria sorbifolia Hardy Flowering Shrub for Borders

False Spirea (Sorbaria sorbifolia) is a hardy, deciduous flowering shrub grown for its fern-like foliage and large, feathery plumes of tiny white flowers in summer. It forms a full, bushy shape that works well as a backdrop or mass planting in mixed borders.

Grown as an ornamental shrub for borders, hedges, and naturalized areas, it spreads readily by suckers to fill space over time. Suited to temperate gardens with moist, well-drained soil, it is generally low maintenance once established. Seeds are small and best started indoors or in a nursery bed before transplanting.
