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, and 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 effects.
- 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.
