Caltha palustris Plena

Caltha palustris Plena is a semi-aquatic perennial herbaceous plant with a rhizome, found on the edge of water and banks. It is very hardy and one of the first spring flowers in ponds and watercourses. With its double yellow flowers, the Double Marsh Marigold produces better flowers in full sun but can illuminate partially shaded areas in the heat of summer. The Double Marsh Marigold is a nectar-rich plant that is useful for many pollinating insects in early spring. It can be grown in any good garden soil as long as there is sufficient moisture.

In a small rounded clump of 30cm (12in), the Caltha palustris Plena is a remarkable, fresh accent plant full, ideal for the banks of a water feature such as a pond, a lake or even a natural swimming pool, ensuring a transition with the rest of the garden. Its heart-shaped shiny leaves are dark green and deciduous, wide and thick, contrasting well with its imposing flowers composed of a multitude of petals forming an impressive yellow "bud".

Marsh Marigold belongs to the Ranunculaceae family. It is native to temperate regions of the north (Europe and America) where it only grows in wet environments: edges of ditches, streams and marshes and wet meadows. The genus Caltha comes from the Greek word calathos, which means basket, alluding to the shape of the flowers.

Your pond should maintain its balance (i.e. clear water) by combining the following trio: floating plants (Water Lily and Nymph), submerged plants with a strong oxygenating power (Water Milfoil, Pondweed, and Water Lettuce) with shallow water plants on the edge (Japanese Iris, Fern, and Horsetail).

Green the banks with more sophisticated and sculptural plants to create an enchanting tableau, such as Astilbes, Meadowsweets, and other Loosestrifes.
