Visions astilbe

Sun

Partial shade is best; morning sun is suitable where the soil stays moist. Avoid strong afternoon sun in hot climates.

Water

Keep evenly moist, especially during establishment and flowering. Water deeply during dry spells; do not leave the roots in stagnant, waterlogged soil.

Soil

Humus-rich, moisture-retentive but well-drained soil, preferably slightly acidic to neutral. Improve sandy or heavy soils with compost before planting.

Height

1-2 ft (0.3-0.6 m), including flower stems

Spread

1-1.5 ft (0.3-0.45 m)

Flowers

Dense raspberry-pink to rosy-purple plumes in mid- to late summer.

Foliage

Divided, toothed green leaves form a low mound; young growth can have bronze tones. Deciduous.

Growth

Moderate; forms a substantial clump in about 2-3 years.

Care needed

Growth rate

Moderate

• Water at soil level whenever the soil begins to dry; do not let the root ball dry out.
• Apply compost in spring; use a balanced, slow-release fertiliser only if growth is weak or soil is poor.
• Mulch with 2 in (5 cm) of leaf mould or compost, keeping it clear of emerging shoots.
• Divide congested clumps every 3-4 years if flowering declines or the centre becomes sparse.
• Leave space between plants for airflow; staking is normally unnecessary.

Pruning. Leave faded plumes for their seedhead texture, or cut the flower stems to the base after flowering; deadheading does not normally produce another flush. Cut dead foliage close to the ground in late winter or early spring before new shoots appear.

Late winter

Cut away dead foliage and old flower stems before fresh growth starts.

Early spring

Plant or divide clumps, replanting at their original depth and watering thoroughly.

Spring

Top-dress with compost and renew the moisture-retaining mulch.

Summer

Check soil moisture regularly and water deeply during dry weather.

Late summer

Remove spent flower stems if you prefer a tidy finish, or leave them standing.

Autumn

Plant new specimens while the soil is moist and workable; retain healthy dead stems for winter texture if desired.

• Plant in repeated groups along a partly shaded border for a band of pink summer colour.
• Combine with hostas and ferns to contrast upright flower plumes with broad leaves and arching fronds.
• Use beside a pond or stream where the soil stays moist but the crown is not submerged.
• Place near the front of a woodland-edge planting, away from dense tree roots that dry the soil.

Garden styles it suits: Woodland, Cottage garden, Romantic rose garden, Blues and silvers, Japanese and Pacific Northwest woodland.

Plant it with: Hosta, Japanese painted fern, Siberian bugloss, Coral bells, Japanese forest grass and Rodgersia.

Wildlife: The flowers attract bees and other visiting insects. Deer and rabbits often leave astilbes alone, although browsing is still possible.

• Brown leaf edges or scorched foliage: usually caused by dry soil, hot sun or drying wind; water deeply, mulch and provide afternoon shade.
• Poor flowering: check for deep shade, drought or overcrowding; improve moisture, move to brighter filtered light or divide the clump.
• Powdery mildew: improve airflow, avoid drought stress and remove badly affected foliage.
• Root or crown rot: avoid waterlogged sites and planting too deeply; remove rotted plants and improve drainage before replanting.

Astilbe is not known to be toxic to people, cats, dogs or horses; no part is recognised as poisonous. It is an ornamental rather than a food plant, and eating plant material may still cause stomach upset.

• Goat's beard (Aruncus dioicus)

  Usually much taller, with large, loose ivory-white flower plumes rather than compact raspberry-pink heads.

• Queen of the prairie (Filipendula rubra)

  Has broad, deeply lobed leaflets and much taller stems topped with airy pink flower clouds, rather than the low mound and dense plumes of Visions.

Astilbe comes from Greek words meaning 'without lustre', referring to the small individual flowers, while chinensis means 'from China'.

Propagation. Divide established clumps in early spring or early autumn, keeping several healthy buds and roots on each section. Water divisions well while they establish. Seed does not reliably reproduce the named cultivar.

Accepted botanical name

Astilbe rubra Astilbe chinensis 'Visions' is an older name for Astilbe rubra.
