Growth Rate
|
– Moderate; reaches mature size (approx. 2–3 feet tall in bloom) in 1–2 growing seasons

Wildlife Attraction
|
– Attracts bees, small butterflies, and other pollinators
– Foliage and flowers are deer and rabbit resistant |
Self-pollinating
|

Seasonality
|
– Spring: Foliage emerges, often with bronze or reddish tint
– Summer: Blooms from late July into August, later than many other species
– Fall: Foliage yellows, then dies back
– Winter: Dormant; plumes can be left for texture or removed |
Ideal For
|
– Shady beds – woodland borders – waterside plantings – cottage gardens – cut flowers |
Leaf Description
|
– Coarse, deeply cut, fern-like green foliage
– Dense, basal mound; adds texture to shade gardens even when not in bloom
– May have reddish tint on emerging spring leaves |
Flower Description
|
– Upright, dense plumes of creamy white to soft ivory flowers
– Held on tall, sturdy reddish-green stems
– Blooms in mid to late summer, providing contrast to earlier-blooming Astilbes
– Excellent as a cut flower, and can be dried for arrangements |
Planting Instructions
|
– Best time to plant: Early spring or early fall when soil is cool and moist
– Soil: Prefers rich, moist, well-drained soil that is slightly acidic to neutral
– Site prep: Work in compost, peat moss, or leaf mold to increase organic matter
– Spacing: Space 18–24 inches apart to allow full foliage spread and good air circulation
– Planting depth: Plant with crown just at soil level, avoiding deep planting |
Pruning & Maintenance
|
– Deadhead spent blooms if desired to keep appearance tidy
– Cut back entire plant to the base in late fall or early spring to clear dead foliage
– Spent plumes can also be left standing for winter texture |
Water Needs
|
– Requires consistently moist soil—not drought tolerant
– Water deeply 1–2 times per week during dry periods
– Ideal for wet borders, rain gardens, and pond edges |
Light Needs
|
– Part shade to full shade
– Will tolerate morning sun, especially in cooler climates, provided it receives adequate moisture
– Avoid hot, dry, full sun sites |
Harvesting
|
– Excellent cut flower: harvest when 1/2–2/3 of flowers on the plume are open
– For drying, cut when just opening and hang upside down in a dark, ventilated space
– Not used for culinary or herbal purposes |
Fertilizing
|
– Apply organic compost or slow-release balanced fertilizer in early spring
– Avoid high-nitrogen fertilizers, which can promote excess foliage over flowers
– Mulch with shredded leaves or bark to retain moisture and improve soil over time |
Pollination
|
– Self-pollinating; visited by bees and small pollinators
– Flowers are fertile, but propagation is typically via root division, not seed |
Companion Plants
|
– Pairs beautifully with Hosta, Heuchera, Ferns, Brunnera, Ligularia, Tiarella, Pulmonaria
– Works well near water features and shaded borders under Cornus or Magnolia
– Combine with dark-leaved plants or pink/blue flowers for soft contrast |
