Marsh marigold

Marsh Marigold (Caltha palustris) is a perennial plant species in the buttercup family (Ranunculaceae). It is native to temperate and arctic regions in the Northern Hemisphere, typically in wet environments such as marshes, fens, ditches and wet woodlands.

Description

The Marsh Marigold is a herbaceous plant with a fleshy, creeping rhizome. It produces large, glossy, heart-shaped leaves that are 7-20 cm long. The flowers are bright yellow, 2-5 cm in diameter, with 4-9 (usually 5) petal-like sepals and many yellow stamens; they are produced in early spring to late summer.

Distribution and Habitat

Marsh Marigold is found throughout the Northern Hemisphere, from Europe to North America and Asia. It is typically found in wet, marshy areas, hence its common name. It can also be found in wet woodland areas, along the edges of ponds and streams, and in ditches.

Uses

Historically, Marsh Marigold has been used for various medicinal purposes. The plant has been used as a diuretic, an expectorant, and a vulnerary. However, it should be noted that all parts of the plant are toxic and can cause skin irritation or more serious effects if ingested.

In addition to its medicinal uses, Marsh Marigold is also used in landscaping for its bright yellow flowers and its ability to thrive in wet conditions. It is often used in rain gardens, bog gardens, and near ponds or streams.

Conservation

While Marsh Marigold is not currently considered threatened or endangered, it is susceptible to habitat loss due to drainage of wetlands and other changes in water management practices. Conservation efforts are focused on preserving existing populations and restoring suitable habitat.
