Marsh Marigold

Caltha palustris

Marsh Marigold is a cheerful, water-loving plant that thrives in marshes, wet meadows, and boggy areas. Reaching up to 1 to 2 feet in height, it features large, glossy, kidney-shaped leaves that provide a lush backdrop to its bright yellow, buttercup-like flowers. Blooming profusely in early spring, the flowers are a vital food source for early bees and other pollinators. This plant is ideal for naturalized wetland gardens, pond margins, or as part of a rain garden where its moisture requirements can be naturally met.

A special note, Marsh Marigold bears great resemblance to the highly invasive Lesser Celandine (Ficaria verna) which also grows in similar environments. Lesser Celandine typically blooms about a month earlier than Marsh Marigold, around March or early April, and should be removed if found.

Ecological Benefits

Maintenance Tips

  • Requires consistently moist to wet soil; does not tolerate dry conditions.
  • Minimal pruning is needed; deadhead spent flowers if a tidy appearance is desired.
  • Thrives in wet, boggy soils rich in organic matter.
  • Marsh marigold is generally low-maintenance but watch for slug and snail damage, especially on young foliage.
  • Note: very similar appearance and environmental preferences to invasive Lesser Celandine, which should be removed if positively identified.
