Astilbe × arendsii 'Fire' ('Feuer') (False Goat's Beard) — Clump-forming, upright plumes above a mound of foliage

Overview

Astilbe × arendsii 'Fire' ('Feuer') 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 × arendsii 'Fire' ('Feuer') 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. Suggested uses include borders, woodland gardens, shade gardens, near water features and and moist garden beds..

About

Astilbe × arendsii 'Fire' ('Feuer') is a clump-forming perennial producing upright, feathery flower plumes above a mound of finely divided foliage. Leaves are deciduous, deeply divided and toothed, often bronze-tinted when young. It flowers June to August and requires reliably moist to boggy soil in partial shade, with full sun only where the soil remains wet.

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 × arendsii 'Fire' ('Feuer') is a perennial in the Saxifragaceae with an upright, clump-forming habit: feathery plumes stand above a dense mound of deeply divided, toothed leaves that often show a bronze tint as they emerge. Flowering runs from June to August, providing mid-summer vertical texture in shadier parts of the garden. Plant into fertile loam or heavy clay that has been enriched with plenty of organic matter and keep the root area consistently moist; the cultivar will not tolerate drought. Position in partial shade—north, east or west-facing sites are appropriate—and only use in full sun where the soil stays reliably wet. Give a sheltered spot to reduce wind damage to the plumes and to preserve the finer foliage. Rated H7 (fully hardy), it suits the majority of UK gardens when moisture needs are met. Use it in mixed borders, shade and woodland plantings, beside ponds and water features, or in any moist garden bed where its upright summer plumes can be seen above lower companions. Expect upright, feathery flower plumes from June to August rising above bronze-tinted new foliage.

Care notes

Pruning and caring for Astilbe × arendsii 'Fire' ('Feuer')

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.
