How to Grow
Astilbe ‘Rheinland’ should be planted in spring or fall, ensuring the location offers part shade to full shade protection from hot afternoon sun. The key to success lies in the soil: aim for average, medium moisture, well-drained conditions that are also humusy and organically rich. Introducing plenty of compost before planting will help establish the moisture-retentive base this Astilbe prefers.
Once established, consistent watering is crucial; the soil for Astilbe must never be allowed to dry out completely. If kept regularly watered, the attractive fern-like foliage of Astilbe ‘Rheinland’ will remain appealing all season. Apply a summer compost mulch generously around the base of the plant to aid in retaining crucial soil moisture during warmer spells.
Maintenance for this low-care perennial is minimal. While removing faded flower stalks after bloom can tidy the appearance, many gardeners choose to leave the dried seed heads in place for ongoing winter interest. Clumps of Astilbe should be divided every three to four years when they begin to look overcrowded, typically done in spring or early fall.
Landscape Uses
Astilbe ‘Rheinland’ excels in mass plantings or groupings where consistent shade darkens the garden floor. Because of their medium moisture needs and tolerance for deep shade, they are perfect companions for woodland gardens, creating a lush, layered effect beneath taller trees or shrubs. They perform beautifully along shaded border fronts where their clear pink blooms draw the eye into the scene.
Consider Astilbe ‘Rheinland’ for utilizing foundation plantings that receive limited sun exposure throughout the day. They also serve as excellent ground cover or edging plants, defining shady pathways or softening hard structural elements. Furthermore, their love for moist soil makes them ideal candidates for planting near pond or stream banks, integrating seamlessly into waterside landscaping schemes.

Companion Planting in Shade
When planning plantings around Astilbe ‘Rheinland’, select other shade-loving perennials that share its need for moist, well-drained conditions. Hosta varieties with blue or gold foliage provide excellent contrast against the dark green texture of the Astilbe leaves. Ferns, particularly Japanese Painted Ferns or Ostrich Ferns, complement the airy plumes beautifully. Consider the addition of Bleeding Hearts (Dicentra) or Tiarella (Foamflower) for continuous low-level spring and early summer interest in deep shade settings.
Seasonal Care Calendar
Spring is the ideal time to apply a fresh layer of compost mulch around your Astilbe clumps to lock in moisture for the coming summer heat. As temperatures rise, diligently monitor soil moisture, increasing water frequency if the foliage shows any sign of browning; this is critical care for Astilbe. In the fall, after the clear pink blooms have faded to dried seed heads, you can either cut the stalks down to the crown for a neat winter appearance or leave them standing for winter texture. Cold hardiness is excellent, requiring no special winter protection in Zones 4-8.
