Astilbe 'Red Sentinel' (Japonica Hybrid)
Astilbe Japonica 'Red Sentinel', False Spirea 'Red Sentinel', False Goat's Beard 'Red Sentinel'
One of the best red Astilbes, Astilbe 'Red Sentinel' (Astilbe japonica) features vibrant crimson red flower plumes borne on erect, mahogany-red stems. Standing out in shady borders, they rise gracefully in early to mid-summer above an attractive mound of fern-like deep green, glossy foliage. Long-lasting, they turn a rich caramel color which provides winter interest to the garden.
- Fairly compact and bushy, this Astilbe grows up to 18 in. tall (45 cm), extending to 30 in. with the flowers (75 cm), and spreads 18-24 in. (45-60 cm). The refined, fern-like foliage remains attractive all season long (under satisfactory growing conditions).
- 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!
- 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, woodlands, near streams and ponds, or in containers. Plant 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.
