In the garden

Astilbe 'Bumalda' sits within the genus Astilbe and forms tidy clumps of summer-flowering stems; the foliage dies back in winter as it is deciduous. Flowering occurs in the UK from June to August, providing reliable midsummer presence where moisture is available. Place Astilbe 'Bumalda' in partial shade, ideally a north-facing, sheltered spot where soils do not dry out. It prefers a neutral loam kept moist but well drained; avoid locations that alternate between drought and waterlogging. The cultivar is fully hardy (H7) in UK conditions and will survive winter frosts when sited out of strong exposure. Use it at the water's edge, in a bog garden or within damp border compositions where soil remains consistently damp. Its clump-forming habit helps define edges and it complements planting where prolonged summer moisture is a feature. Flowerheads that appear from June to August hold their shape long enough to give structure at waterside margins and damp beds.
