This semi-aquatic is a strong grower and fills a small pond fast. Please keep away from water courses! Can be grown in a tub or kiddy pool, but not be submerged in water.
- Perennial evergreen herb to 60 cm
- Wet fertile soil or shallow water and a sunny position, spreads rapidly.
- Could be used as a ground cover plant in wet areas.
- The flavour is reminiscent of carrots or parsley; leaves and roots edible.
Even though the plant is sometimes called ‘Korean Watercress’, watercress is not a substitue, it tastes completely different.
The picture shows a small pool, maybe 1.00 m x 70 cm planted with water dropwort and some water chestnuts. There is conflicting information on the frost hardiness of water dropwort, it can handle some frosts, but I cannot tell for sure how much. In doubt overwinter a small piece inside, it will fill the pond during summer! The preferred climate of this plant is warm temperate or subtropical.
Common names: Water parsley, Chinese celery, filipendula de aqua, minari, 水芹, Rau Can, Can Nuoc (Viet); Seri (Japan); Komprek (Manipur, India), Korean watercress.
