About Water mint
Mentha aquatica, commonly known as water mint, is a perennial herbaceous plant from the Lamiaceae family, characterized by its square stems, oval and aromatic leaves, and small purple flowers in terminal spikes. It is ideal for pond edges, water gardens, or moist pots, where its fragrance and texture can be appreciated. Its vigorous growth makes it an excellent choice for covering wet and boggy areas.
Native range
Europe and Western Asia, parts of North Africa
Care tips
Water mint thrives in full sun to partial shade, requiring at least 4-6 hours of direct sunlight daily. It needs consistent and abundant watering, keeping the substrate always moist, and can even grow partially submerged in shallow water. The ideal substrate is rich in organic matter and well-draining, although it tolerates heavier soils if kept moist; avoid letting the soil dry out completely, as this will stress the plant and affect its growth.
