Astilbe Dwarf Garden hybrids (False Goat's Beard) — Clump-forming, upright plumes above a mound of foliage

Overview

Astilbe Dwarf Garden hybrids is a clump-forming, upright plumes above a mound of foliage perennial in the genus Astilbe, part of the Saxifragaceae family, with deciduous; deeply divided and toothed, often bronze-tinted when young foliage. Astilbe Dwarf Garden hybrids grows best in partial shade; full sun only where the soil stays reliably wet, and tolerates fertile loam or clay enriched with organic matter soils and neutral to slightly acid pH. Its UK hardiness is rated H7.

About

Astilbe Dwarf Garden hybrids are clump-forming perennials producing upright flower plumes above a mound of deeply divided, toothed leaves. The foliage is deciduous and often bronze-tinted when young. Flowering occurs from June to August, with the plumes sitting clear of the leaf mound. Plants need reliably moist to boggy soil and will not tolerate drought.

About the genus

Astilbe is a genus of 18 species of rhizomatous flowering plants within the family Saxifragaceae, native to mountain ravines and woodlands in Asia and North America. Some species are known by the common names false goat's beard and false spirea.

In the garden

Astilbe Dwarf Garden hybrids form upright plumes carried above a compact mound of deeply divided, toothed leaves; the foliage is deciduous and frequently shows a bronze tint when young. Flowering takes place from June to August. Their habit—tall flower stalks emerging from a leafy clump—makes them a useful vertical accent where moisture and shade coincide. Site them in partial shade; they will only tolerate full sun where the soil remains reliably wet. Choose a sheltered spot on a north, east or west-facing aspect to protect foliage and flower stems from drying winds. Soil should be fertile loam or clay enriched with organic matter, with a neutral to slightly acid pH; consistently moist to boggy conditions are essential as these plants will not tolerate drought. Rated H7 (fully hardy) in UK terms, Astilbe Dwarf Garden hybrids will survive winter outdoors but will perform best where summer soil moisture is maintained. In a UK garden they suit damp borders, shaded beds with rich soil and any planting where water availability can be relied on through the growing season. Expect the upright summer plumes to rise clearly above the bronze-tinged foliage from June to August.

Care notes

Pruning and caring for Astilbe Dwarf Garden hybrids

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.
