• Depth of water: 0-5cm
• Rate of growth: average to fast
• Flowering period: April
• Hardiness: fully hardy
  
  The kidney-shaped dark green leaves of this lovely marsh marigold are excellent for softening the edges of a pond. One of the first marginal plants into bloom, it produces a mass of waxy, yellow buttercup-like flowers in April. It is ideally suited to boggy conditions, and will cope with shallow water rise and fall normally seen in seasonal pond level changes.
  
  
• Garden care: Plant in reliably 'boggy' ground. Low maintenance, caltha will often re-grow and flower again in autumn if cut back hard in summer. Once established, lift and divide overly-large clumps in late spring.
