Pennyroyal (Mentha pulegium) is a wonderful native plant that brings fragrance, wildlife value, and natural charm to damp gardens, pond edges, and containers. This low-growing, aromatic perennial forms a creeping mat of peppermint-scented foliage, perfect for ground cover or softening the edges of ponds.
From mid to late summer, it bursts into life with clusters of pretty lilac-blue flowers, buzzing with bees, butterflies, and other pollinators. As part of the mint family, it’s a fantastic nectar source and also supports caterpillars, making it a great choice for wildlife-friendly spaces.
Happy in wet soil, shallow water, or even spilling over the sides of containers, Pennyroyal is less vigorous than Water Mint – ideal for smaller ponds. Plus, it helps naturally condition water while adding a lush, fragrant touch to any garden.

Repotting Instructions
Can also be planted in soil – do not allow to dry out in warm weather.
9cm marginal plants require potting into a mesh basket. Place in a pond no deeper than 1/3 maximum recommended planting depth to allow the plants to establish.
1ltr marginal plants do not require repotting but will benefit from a bigger basket, there is no need to remove the mesh basket. Place in pond no deeper than 1/2 maximum recommended planting depth to allow the plants to establish. Plants over 60cm height growth will benefit from repotting into a larger mesh basket or should be planted in gravel to prevent them from falling over in a breeze.
3ltr and 5ltr plants do not require repotting; there is no need to remove the mesh basket. Place on the shelf of the pond at the required depth.
