Caltha palustris
In marshes, river-meadows and wet copses in spring, the Marsh Marigold is a very conspicuous plant, and its acquisition by the rambler often results in wet feet. In some districts it is known as the King-cup, and in Scotland it is called the Luckan Gowan.
The flowering period usually extends from March to May, but in some places flowers may be found as late as August.
