In the garden

Astilbe Dwarf Garden hybrids 'Praecox Alba' belongs to the Saxifragaceae and grows as a clump-forming perennial with upright plumes held above a mound of finely divided, toothed leaves. Young foliage often shows a bronze tint. In the UK it flowers from June to August, providing mid-summer vertical interest. Choose a north-, east- or west-facing site with some shelter and reliably moist soil. It prefers fertile loam or clay enriched with organic matter and does best in neutral to slightly acid conditions. This Astilbe will not tolerate periods of drought, so keep soil consistently moist to boggy; plant it in full sun only where the ground stays reliably wet. It is fully hardy (H7) and will survive typical UK winters when given the recommended conditions. Use 'Praecox Alba' in mixed borders, woodland or shade gardens and beside ponds or other water features where moisture is constant. The upright plumes sit above the bronze-tinted young foliage and provide a summer display from June to August, making it useful for adding vertical texture in shady, damp spots.

Care notes

Pruning and caring for Astilbe Dwarf Garden hybrids 'Praecox Alba'

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.
