White Gloria Astilbe
Dense Pure-White Plumes for Brightening the Shade
White Gloria Astilbe (Astilbe japonica 'White Gloria') produces full, dense plumes of clean white that light up shaded, moist beds in summer over compact mounds of glossy green foliage. White astilbes are a designer's secret for adding brightness and contrast to dim corners, and White Gloria is among the most reliable and floriferous. Deer-resistant and pollinator-friendly, it's a luminous staple for Edina, Maple Grove, and Woodbury shade gardens.

Landscape Uses
Use White Gloria to brighten shaded borders, woodland gardens, and rain gardens. White plumes glow at dusk and pair beautifully with hostas, ferns, and colored astilbes; they also cut and dry well.
Best Time to Plant
Plant in spring or early fall, when cool weather and steady moisture help roots establish. Avoid midsummer heat.
How to Plant
Dig a hole twice as wide as the root ball and just as deep. Set the crown level with the soil, backfill with compost-enriched soil, water thoroughly, and mulch 2–3 inches deep to conserve moisture.
Watering
First Year: Keep the soil consistently moist, watering 2–3 times per week. Astilbe must not dry out.
After Year One: Continue regular watering, especially in heat.
Drip Irrigation: A soaker hose or drip line provides the steady moisture astilbe needs.

Is White Gloria Astilbe Right for Your Yard?
White Gloria is ideal for shaded, consistently moist Minnesota beds — woodland borders, the north side of the house, or a rain garden — where its white plumes brighten dim corners and deer leave it alone. It's not a fit for hot, dry full sun or soil that dries out, as the plumes and foliage will scorch.
