Immensely popular, Astilbes are fabulous plants for shady, moist conditions. They light up your shade garden for weeks with their elegant flower plumes and add a dazzling splash of color to the landscape. Ranging from 6 in (15 cm) to 24 in. tall (60 cm), their feathery plumes, in shades of lavender, pink, red, or white, can be incredibly striking. They rise gracefully above attractive mounds of fern-like foliage which remains attractive all season long (under satisfactory growing conditions) before turning progressively a rich caramel color which provides winter interest to the garden.

• Relatively trouble-free, Astilbes require little maintenance, are heavy shade tolerant, attract butterflies, but are deer and rabbit resistant! The perfect perennial for a shady border with dappled light!
• These part shade to full shade lovers thrive in organically rich, evenly moist, well-drained soils. Easy to grow, their biggest enemy is dryness - so don't let the soil dry out! While Astilbes can grow in deep shade, it should be noted that they will not flower as much.

• Astilbes can take some sun, especially if you’re a gardener who lives in a region with cool, moist summers. Just make sure to keep your plants well watered, and be aware that full sun can scorch or burn their fern-like foliage.
• Astilbes bloom between late spring and late summer. They flower over a fairly long season since each flower plume consists of hundreds of densely packed tiny flowers, opening in succession. However, they do not all flower at the same time and are classified with a blooming time, ranging from Early to Late season. Therefore, to fill your garden with continuously blooming Astilbes throughout the season, you may plan to plant a variety of cultivars, from Early- to Late season bloomers.

• Native to China, Japan, and Korea, there are about 25 species of Astilbes and hundreds of cultivars, some less than 12 in. tall (30 cm) while others can easily reach 4 ft. in height (120 cm) and are better suited for the back of the border.

Astilbe 'Europa' (18-24 in. - 45-60 cm)

Astilbe 'Amethyst' (36 in. - 90 cm)

• Their diversity in height makes Astilbes quite versatile, and they overachieve in providing a spectacular flower show, whether planted in perennial borders, woodlands, streams, ponds, or containers.
• Good dwarf varieties include 'Darwin's Dreams', 'Fanal', 'Younique', 'Jump and Jive', 'Vision', Pumila, 'Sprite' or 'Bronze Elegance'. They are quite compact and suitable for small gardens, the front of perennial borders or containers, reaching only 12-18 in. in height (30-45 cm).

• The larger varieties of Astilbes make a striking focal point or specimen plant thanks to their sculptural qualities. They also create outstanding backdrops for perennials and shrubs. Among the most spectacular, Astilbe chinensis var. tarquetii 'Purpurlanz', with showy lance-shaped purple flower spikes rather than tufted plumes rising 4 ft. high (120 cm) above fern-like mounds of dark green glossy foliage.

• Astilbe chinensis var. tarquetii 'Superba'  is one of the tallest varieties of Astilbes and always creates a dramatic statement in the garden, with its stunning, purple-rose, lance-shaped flower plumes rising to 4-5 ft high (120-150 cm). They rise gracefully in mid to late summer, on strong, erect flowering stems above an attractive mound of fern-like foliage which emerges mahogany-red before changing to dark green. This fabulous Astilbe has won the Award of Garden Merit of the Royal Horticultural Society.

Plant your Astilbes in groups for better visual effects (5 or more) in a corner of the garden or in drifts around evergreens. If you are an unconditional Astilbe lover, select several Astilbe varieties with different flowering periods to enjoy their incomparable beauty longer! Their flower plumes also make excellent fresh-cut flowers and can be dried in natural bouquets. Include a few Astilbes in your cutting garden where they will attract happy butterflies. 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. Create pretty garden scenes and combine your Astilbes with their favorite companion plants such as Japanese Irises (Iris Ensata), Siberian Irises (Iris sibirica), Peonies (Paeonia), Daylilies (Hemerocallis) in partial shade to full sun sites. Mix them with Plantain Lilies (Hosta), Columbines (Aquilegia), Bleeding Heart (Dicentra), Coral Bells (Heuchera), Meadow Rue (Thalictrum aquilegifolium), Heartleaf Bergenia (Bergenia cordifolia) or with Ferns in shady locations.

• In this summer garden, the luminous, pure white flower plumes of Astilbe 'Deutschland' create a charming display when combined with the deep purple-blue flower spikes of Salvia 'Caradonna' and the blue-colored flowers of great decorative beauty of Geranium 'Rozanne'. This planting is enriched with the flat umbel flowers of Achillea, the bright pink blossoms of Rosa 'Fortuna', and the handsome mound of ovate, dark green leaves with creamy markings of Hosta crispula - all contributing to a lovely summer scenery.

Growing Astilbes

• Astilbes are undemanding and very hardy (USDA Zones 4 - 9). Some are even hardy to zone 3. While they overwinter well, it is still recommended to apply a layer of mulch.
• Astilbes can be grown from seed. Sow seeds early in the spring indoors, or directly into your garden after both weather and soil have warmed up. Note that seeds may be difficult to germinate and it is easier to plant Astilbe plants.
• Astilbes thrive in part shade to full shade in organically rich, evenly moist, well-drained soils. Make sure your soil drains well and does not puddle or get water-logged in rain. Mulch should be added to reduce water evaporation and maintain moisture. Note that Astilbes may be planted in full sun in areas with cool summers and with adequate moisture. In hot summer areas, shade is important.
• Astilbes are heavy feeders. In addition to rich soil, feed them with a fertilizer high in nitrogen, regularly.
• After blooming, feel free to clip off any spent flower stems if you do not like their look. Your Astilbes will continue to provide attractive foliage until fall. After the first frost, the leaves may be yellow and may be trimmed until fresh growth appears next spring.
• Most Astilbes spread easily, so divide your plants every 3 to 4 years to prevent overcrowding, keep them vigorous and assure the maximum number of blooms.
