Originating from Japan, and Korea.
Elegant and lush, with bold, beautifully pointed, and strikingly veined, lobed large maple-like leaves that appear to encircle the upright herbaceous stems as they emerge. Evoking the tropics in moist and shady parts of the garden, it forms a large, slowly spreading mound-shaped clump with a strong autumn yellow leaf colour.
Its classy-looking spikes of deep golden tubular flowers have a crystalline lustrousness, with widely flared petals, appearing over a long period in late summer and autumn, borne on dusky, purple-flushed stems. The flowering stems bear many buds, each held on its own slender stem, with a two-tone look; their green sepals wrapping around the base of the emerging petals. The many open and airy, graceful ‘sprays’ of bud and flower give the plant a stunning appearance, borne in profusion over a long period from mid-summer. These are followed by charming ‘sputnik’ like seed pods with antenna-like spikes.
Thriving in woodland conditions this lush plant is a great mid-level, rounded choice for underplanting taller species in Jungle, woodland, and oriental style gardens, such as Catalpa bignonoides ‘Aurea’ or Catalpa erubescens ‘Purpurea’, or larger growing Acers like ‘Bloodgood’, ‘Going Green’ or ‘Burgundy Lace’.
Easy to grow in all but alkaline soils in moist full shade or dappled shade.
Height and spread after 2 – 5 years 1.5m x 1.5m.
