In the garden

Astilbe Dwarf Garden hybrids 'Serenade' belongs to the Saxifragaceae family and grows as a clump‑forming perennial with upright flower plumes above a mound of divided, toothed leaves. The foliage is deciduous and commonly shows a bronze tint on young shoots. Flowering in the UK runs from June to August, when the erect plumes rise clearly above the leaf mound. Plant into fertile loam or clay that has been enriched with plenty of organic matter; the soil should be neutral to slightly acidic. Sitings on north, east or west facing aspects are preferred and a sheltered position will reduce wind scorch to the upright stems. Provide partial shade; only place in full sun where the ground remains reliably wet. The species requires reliably moist to boggy soils and will not tolerate drought. Hardiness rating H7 means the plants are fully hardy in UK gardens; they will survive typical winter conditions with minimal winter protection. Use 'Serenade' where soil moisture can be maintained—for example in shaded borders, damp, sheltered beds or locations with heavy, moisture‑retentive soils. Expect the June–August flowering to add upright summer interest above the bronze‑tinged foliage.

Care notes

Pruning and caring for Astilbe Dwarf Garden hybrids 'Serenade'

Cultivation: Moisture is everything - an astilbe that dries out scorches at the leaf margins and the plumes shrivel before they open. Plant in ground improved with plenty of organic matter, mulch generously each spring, and site out of hot afternoon sun unless the soil is genuinely wet. They are excellent in the damp shade where little else thrives.
Pruning: No pruning needed. Leave the spent plumes standing for winter structure and cut the whole clump down in late winter before new growth begins.
Propagation: Divide congested crowns in early spring; the woody rootstock may need a spade or a saw. Species can be raised from seed but cultivars will not come true.
Pest resistance: Largely trouble-free, though vine weevil grubs attack the roots of container plants.
Disease resistance: Healthy in suitable conditions. Powdery mildew appears on plants under drought stress, which is a symptom of the wrong site rather than of disease pressure.
