Caltha Palustris, otherwise known as Marsh Marigold or sometimes Kingcup, is the earliest flowering of the commonly grown pond plants. It blooms in late March/early April bringing golden yellow brightness to your pond or pool. When planted into a 5lt planting crate it grows to form a satisfying clump of small, lime green leaves under a canopy of bright, buttercup yellow flowers.
