Marsh Marigold - Excellent Marginal Plant for Smaller Ponds

The Marsh Marigold (Caltha) is a hardy herbaceous perennial suitable for growing in marshy ground, around pool margins or in shallow water. It is an easy to grow marginal plant which is non invasive and therefore suitable for the smaller pond. It grows in water up to 6 inches deep and produces an abundance of lovely yellow/white flowers in April/May. If you remove the dead flowers as soon as they have faded, it will often produce a second flush of flowers in the autumn.
The variety I grow as a marginal plant in my pond is Caltha palustris which is native to Britain and Europe. It has flowered early this year due to the unusually warm March weather. It grows to about 12-15 inches in height with a spread of around 12 inches, and if grown in water as a marginal plant will require a container of at least 6 inches in depth.
The plants can be propagated by lifting and dividing the roots in May or June after flowering has finished.
