Kingcups or marsh marigolds can be found growing wild alongside streams and in shallow water around ponds, where their foliage forms loose clumps of kidney-shaped leaves, in spring and summer large, shiny double yellow flowers like giant, waxy buttercups appear. These plants enjoy moist conditions and can be grown in shallow water round the edge of a pond, where they look fantastic as there flowers are reflected in the water. They also make good bog garden plants, and grow well in borders that waterlog in winter.
