Astilbe 'Rhythm And Blues' (Arendsii Hybrid)

Astilbe x Arendsii 'Rhythm And Blues', False Spirea 'Rhythm And Blues', False Goat's Beard 'Rhythm And Blues'


Perfect for small gardens, Astilbe 'Rhythm And Blues' (Arendsii Hybrid) is a compact, clump-forming perennial boasting bright raspberry-pink flowers held in fluffy plumes. Blooming in early summer, each plume consists of hundreds of densely packed tiny flowers opening in succession for a long lasting floral display. The blossoms are held on sturdy stems and rise gracefully above an attractive mound of fern-like, dark green leaves. The densely incised foliage remains attractive all season long under satisfactory growing conditions. This elegant Astilbe is relatively trouble-free, requires little maintenance, is heavy shade tolerant, attracts butterflies but is deer and rabbit resistant. The perfect perennial for a shady border with dappled light.

  • Grows up to 26-28 in. tall (65-70 cm) and 20-24 in. wide (50-60 cm)
  • Part shade to full shade lover, this Astilbe thrives in organically rich, evenly moist, well drained soils. Don't let the soil dry out! Mulch should be added to reduce water evaporation and maintain moisture.
  • May be planted in full sun in areas with cool summers with adequate moisture. In hot summer areas, shade is important.
  • Provides a spectacular flower show, whether planted in perennial borders, woodland gardens, near streams and ponds or in containers. Plant in groups for better visual effect.
  • Plumes make excellent fresh cut flowers and are great for drying in natural bouquets.
  • No serious pest or disease issues. Keep an eye out for powdery mildew.
  • No deadheading is required unless you do not like the look of the faded flower stalks. If allowed to remain, the dried seedheads will provide additional interest later in the season.
  • Should be divided about every 4 years to assure the maximum number of blooms.
  • Propagate by division in late winter or early spring, pot divisions under glass and plant out in late spring..
