Growing notes
- Plant in dappled to deep shade — the iconic blue-leaved hosta for shade-garden centrepieces, eventually 1 m across
- Distinct from the base hosta entry already in the database — ‘Elegans’ is the specific large-leaved blue Siebold cultivar
- Slug and snail damage is the main pest issue — large soft leaves are particularly attractive to molluscs
- Long lived once established — divide every 5–7 years to maintain vigour
