Caltha Palustris

Marsh Marigold

A cheerful, moisture-loving perennial valued for its bright yellow spring flowers and lush, glossy foliage. Large, buttercup-like blooms appear in early to mid-spring, rising above rounded, dark green leaves and bringing early-season color to wet sites and cool gardens.

Growth is clump-forming and spreading by short rhizomes, creating a bold, naturalistic presence in consistently moist soils.
