Astilbe 'Montgomery' (Japonica Hybrid)

Astilbe Japonica 'Montgomery', False Spirea 'Montgomery', False Goat's Beard 'Montgomery'


Standing out, Astilbe 'Montgomery' (Astilbe japonica) is a compact, clump-forming perennial boasting dark magenta red flowers held in dense plumes. Blooming in early to mid summer, each plume consists of hundreds of densely packed tiny flowers opening in succession for a long lasting floral display. They are held on upright, dark red stems and rise above an attractive mound of fern-like, deep green, glossy foliage, which emerges bronze-red in spring. Long-lasting, the flower plumes turn a rich caramel color which provides winter interest to the garden. This award-winning 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.

  • Recipient of the prestigious Award of Garden Merit& of the Royal Horticultural Society.
  • Grows up to 20-24 in. tall and 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 ponds and streams 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.
