Water celery is a vigorous perennial that thrives in wet conditions where most vegetables struggle. This low-growing herbaceous plant spreads across moist ground via creeping stems, reaching 12 to 24 inches tall and spreading 24 to 30 inches wide. Native to marshes, wet meadows, and shallow water across Mongolia, China, Japan, Korea, and Southeast Asia, it's earned multiple common names, Java water dropwort, Indian pennywort, Chinese celery, reflecting its wide cultivation. Hardy in zones 3 through 9, water celery produces showy flowers from July through September and tolerates wet soil conditions that would challenge ordinary vegetables. The edible foliage grows easily in medium to wet soils in partial shade, making it an uncommon choice for gardeners with boggy spots or rain gardens.

Water celery spreads rapidly through stolons, rooting at the nodes and self-seeding to form colonies in rich moist soils. Its fibrous root system and decumbent (trailing) stems make it exceptionally low-maintenance once established, thriving in partial shade where sunlight is limited. The showy flowers that bloom from July through September add ornamental interest alongside edible foliage. Because it encounters no serious insect or disease problems, gardeners can focus on managing its vigor rather than fighting pests.
The edible foliage serves culinary purposes across Asian cuisines, where it appears fresh and cooked in various preparations. Its ability to thrive in waterlogged conditions also makes it valuable for ecological uses like naturalizing in rain gardens and wet areas, helping stabilize muddy banks and ditches while providing food.

Harvest the edible foliage by cutting leaves and stems as needed throughout the growing season. Young growth offers the most tender material for culinary use.
Regular management of water celery keeps its spreading habit in check, particularly in rich, moist soils where it can become invasive. Cut back growth as needed to prevent it from overwhelming neighboring plants, especially when grown in rain gardens or other wet areas where it might self-seed prolifically.
