Growing notes

  • Plant as a single specimen in dappled shade or part sun (more sun for the brightest gold colour) — eventually 1.5 m across
  • Notably thick leathery leaves are far more resistant to slug damage than thin-leaved hostas
  • Distinct from the base hosta entry already in the database
  • Tolerates more sun than most hostas — the gold colour develops better with some direct morning sun
