Pretty in Pink Astilbe
Soft Pink Plumes That Brighten the Shade
Pretty in Pink Astilbe (Astilbe × arendsii 'Pretty in Pink') lights up shady borders with full, feathery plumes of clear, soft pink rising above mounds of fern-like green foliage in summer. It's the kind of dependable, easy-care perennial that turns a dim, damp corner into a highlight, feeding pollinators while shrugging off deer and rabbits. A graceful, long-blooming choice for Minnetonka, Lakeville, and Blaine shade gardens.

Landscape Uses
Use Pretty in Pink in shaded borders, woodland gardens, rain gardens, and along water features. The plumes are excellent cut or dried, and the plant combines beautifully with hostas, ferns, and astilbes in other colors.
Best Time to Plant
Plant in spring or early fall, when cool weather and steady moisture help roots establish. Avoid the heat of midsummer.
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. Do not let astilbe dry out.
After Year One: Continue regular watering, especially during heat.
Drip Irrigation: A soaker hose or drip line provides the steady moisture astilbe requires.

How Many Pretty in Pink Astilbe Do I Need?
Astilbe makes its best impact massed in a shady drift. At a mature spread of about 18–24 inches, plant on roughly 20-inch centers and figure about one plant for every 1.7 feet of bed run.
| Bed Run | Plants Needed (at 20 in. spacing) |
|---|---|
| 5 ft | 3 plants |
| 10 ft | 6 plants |
| 15 ft | 9 plants |
| 20 ft | 12 plants |
For a fuller look faster, set plants in odd-numbered groups of 3–5 about 20 inches apart.
Pretty in Pink Astilbe Season-by-Season in Minnesota
- Spring: Fern-like green foliage unfurls early, filling damp, shaded corners before most perennials wake up.
- Summer: Full, feathery soft-pink plumes rise above the foliage — the main event — drawing bees and butterflies.
- Fall: Plumes fade to warm tan and can be left for texture as the foliage takes on bronze tints.
- Winter: Dies back to the ground; a 2–3 inch mulch protects the crown, and it returns reliably in zone 4.

Is Pretty in Pink Astilbe Right for Your Yard?
Pretty in Pink thrives in part-to-full shade with rich, consistently moist soil — woodland borders, north-facing beds, rain gardens, and the edges of water features. It is not a fit for hot, dry, all-day sun or fast-draining spots, because astilbe will not tolerate drought.
