A very good garden plant with many flowers held on strong stems, Astilbe ‘Diamond’ or ‘Diamant’ (Astilbe x arendsii) features graceful, long, slender, pure white flower plumes rising elegantly above fern-like mounds of deep green foliage. Glowing in the shade, each plume consists of hundreds of densely packed tiny flowers, each opening in succession, providing a long season of bloom from early to mid-summer. Long-lasting, the flower plumes turn a rich caramel color which provides winter interest to the garden.

  • Relatively trouble-free, this Astilbe requires little maintenance, is heavy shade tolerant, and attracts butterflies but is deer and rabbit-resistant! The perfect perennial for a shady border with dappled light!
  • Raised by Georg Arends in 1920, this Arendsii Hybrid Astilbe grows up to 24-36 in. tall (60-90 cm) and spreads 18-24 in. (45-60 cm). The refined, fern-like foliage remains attractive all season long (under satisfactory growing conditions).
  • Part shade to full shade lover, this Astilbe thrives in organically richevenly moistwell-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 borderswoodlands, near streamsponds, or in containersPlant in groups for better visual effects. Excellent ground cover or edging plant for shady areas.
  • Plumes make excellent fresh cuts or for drying in natural bouquets
  • 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.
