Plant in a medium or large sized pot with up to 30cm of water above the planting basket. This plant is suitable for zone 2 and 3 of a pond. Aquatic and marginal plants should be placed in pond plant baskets filled with aquatic soil (sold separately) and topped with a thin layer of gravel to help prevent the soil from washing away.

Caring and Maintenance

This plant is very low maintenance but it should be cut back after flowering to prevent it from spreading too far.

Pond Plant Benefits

Marginal and pondside plants add interest, colour and structure to ponds, and offer the benefit of delightful fragrance. They are ideal for places near to patio or decking areas, where their sweet aroma can be appreciated. The plants can be positioned around the perimeter of a pond or on levelled shelves for original and attractive exposure. Marginal plants should be planted in boggy ground or shallow water for optimal growth results.

RHS Award of Garden Merit

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.
