– Summer: Blooms begin in July and can persist several weeks
– Fall: Foliage yellows or bronzes before going dormant
– Winter: Dormant, with stems optionally left for structural interest |
Ideal For
|
– Mass planting – shade borders – mixed beds – floral arrangements
|
Leaf Description
|
– Dense clumps of deep green, coarse, fern-like foliage
– New growth may have a reddish or bronze tint
– Excellent textural contrast in shade plantings
– Holds up well through summer |
Flower Description
|
– Creamy white, plume-like flowers on tall, sturdy, upright stems
– Blooms in mid-to-late summer, often July through August
– Flower plumes arch slightly, giving a soft, feathery look
– Excellent for cut flower arrangements, fresh or dried |
Planting Instructions
|
– Best time to plant: Early spring or early fall
– Use moist, well-drained, humus-rich soil; slightly acidic to neutral preferred (pH 6.0–7.0)
– Enrich planting area with compost or peat moss before planting
– Spacing: Space plants 18–24 inches apart
– Place crown at soil level, not buried
– Mulch generously to conserve moisture and keep roots cool |
Pruning & Maintenance
|
– Deadhead spent flowers if desired, or leave them for fall texture
– Cut back all foliage in late fall or early spring
– Divide clumps every 3–4 years to reinvigorate growth and maintain flower quality |
Water Needs
|
– Requires consistent moisture
– More drought-tolerant than other Astilbes once established
– Excellent for rain gardens, moist borders, or anywhere where the soil remains evenly moist |
Light Needs
|
– Performs best in part shade to full shade
– Tolerates more sun than most Astilbes, especially in cooler climates or if well watered
– Ideal for eastern or northern exposures with filtered light |
Harvesting
|
– Harvest flower stems when half to fully open for fresh use
– Hang upside down in a cool, dry area to dry
– Not used for culinary or medicinal harvesting |
Fertilizing
|
– Apply balanced, slow-release fertilizer or compost in early spring
– Avoid excess nitrogen to maintain compact growth and strong bloom
– Replenish mulch annually for nutrient-rich root zone |
Pollination
|
– Pollinated by bees, flies, and butterflies
– Self-pollinating, but primarily propagated by division
– Not invasive |
Companion Plants
|
– Shade-loving perennials like Heuchera, Hosta, Ferns, Brunnera, Pulmonaria, Tiarella
– Mix with Hydrangea, Ligularia, or Rodgersia for layered texture
– Brightens up dark corners and works well in moist woodland gardens |
