In the garden

Nothosmyrnium japonicum var. sutchuenense 'Loushan Filigree' belongs to the Apiaceae and presents as a well-branched, deciduous garden plant that offers garden interest during spring and summer. The cultivar name identifies its selection; its seasonal presence is limited to the spring and summer months so plan planting around spring bulbs or later-emerging perennials. Plant into a loam-based soil amended with organic matter, keeping the rootzone consistently moist but never waterlogged. It tolerates acid, neutral and alkaline soils, so pH is less critical than good structure and drainage. Choose a partially shaded site that is sheltered from strong winds; it will accept north- through south-facing aspects in a shaded position. The H6 hardiness rating equates to very hardy in UK terms, so it tolerates normal winter conditions when established. Use this cultivar in woodland gardens or shaded borders where its well-branched clumps can fill space between spring bulbs and taller shade plants such as ferns. Give each plant enough room to form a compact group and avoid exposed, drying sites where shelter is lost; planting near established shrubs will help maintain the moist, shaded microclimate it prefers.
