Caring and Maintenance:
This is a very low maintenance plant which requires a well moisturised environment. Propagate by division at the end of summer or very early in spring.
Help to conserve our native British flora by planting with our native plant range. These marginal pond plants grow naturally in the shallow water at the edge of the pond and are ideal for wildlife ponds or water features. As well as their attractive foliage and flowers, they provide a natural habitat for small pond creatures. The rafting varieties, such as the Water Forget-me-not, Brooklime, and Water Mint, spread out in small floating rafts, giving cover to baby fish and tadpoles. The tall emergent plants are essential for dragonflies and damsalfly nymphs to climb out of the water and transform into adults, and waterfowl like to nest among dense reeds and rushes. All plants contribute to the ecological haven of a natural pond, benefiting wildlife from tiny pond insects to mammals that like to visit for a drink.
The Royal Horticultural Society has given Caltha Palustris the prestigious Award of Garden Merit (AGM). The Award of Garden Merit, or AGM, is an award made to garden plants by the British Royal Horticultural Society after a period of assessment by the appropriate committees of the Society. Awards are made annually after plant trials (which may last for one or more years, depending on the type of plant being trialled) at RHS Garden, Wisley and other RHS gardens, or after observation of plants in specialist collections. This is intended to judge the plants' performance for conditions in the UK.
