arendsii ‘Bumalda’ has foamy, full white plumes that have a pink glow and semi-glossy foliage. The icy flowers blush with age to pale pink while contrasting beautifully with the reddish stems and deep, dark bronze-green infused foliage. This perennial thrives in moist, shady locations and is popular for border plantings or alongside water areas. One of the very best white astilbes. Very pretty with small to medium size gold-leafed hostas like Gold Standard. Plant in groups for maximum impact.

Notes: Prefers a moist, slightly acidic, rich humus soil away from afternoon sun. Wilting and dying back can be avoided in hot, dry periods with ample irrigation. Periodically feed with a 5-10-5 fertilizer following label instructions. You can also mulch with well composted manure over Winter. Divide every 3-5 years. Attracts butterflies & hummingbirds and is a good cut flower. The flowers and foliage of the Astilbe are good for cutting and may be used in fresh floral arrangements. The flowers are good for drying. In order to keep Astilbe looking good for the next year, do not cut it back in the winter, (the old foliage helps protect the plant from winter damage), but prune in early spring. Astilbe can be used in perennial borders or shade gardens with Hostas and Ferns and alongside water areas.
Planting instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly.
