Marsh Marigold (Caltha palustris)
The large, golden flowers of Marsh-marigold certainly look like the cups of kings; indeed, the Latin name, Caltha,is derived from the Greek for ‘goblet’, and this plant is also commonly known as ‘Kingcup’.
It is a widespread flower of ponds, marshes, damp meadows, ditches and wet woodland and is a conspicuous spring flower.
Marsh-marigold is also a good plant to add to a wildlife-friendly pond, providing shelter for frogs and early nectar for insects.
