Feathery Plumes for Shade Gardens
Bring elegance to shady beds with Astilbe, a moisture-loving perennial prized for feathery plumes in pink, white, and red. Blooming from late spring into midsummer, Astilbe’s fernlike foliage and flowers add texture and color to woodland borders, shade gardens, and containers.
