White water spinach (Ipomoea aquatica) is a fast-growing aquatic vine with hollow, crisp stems (often white) and arrowhead-shaped leaves, related to sweet potatoes, prized in Asian cuisine for its mild, slightly sweet flavor and crisp texture, used in stir-fries, soups, or salads, offering nutrients like vitamins, minerals, and fiber.
Stems: Hollow, spongy, and can grow long, allowing them to float; they are often white or light green and root at nodes.
Leaves: Light green, arrowhead (sagittate) or heart-shaped, smooth, and float on water.
Flowers: Trumpet-shaped, typically white or pale purple with a mauve center.
Flavor & Texture
Taste: Mild, slightly sweet, and spinach-like.
Texture: The leaves are tender, while the hollow stems offer a pleasant crispness when cooked.
Habitat: Grows in water or moist soil in tropical climates.
Varieties: "White stem" and "green stem" are common; the white-stemmed type is often considered more tender and flavorful.
Uses: Stir-fried (especially with garlic/oyster sauce), added to soups, or eaten raw in salads.
Nutrition: Rich in vitamins, minerals (iron, calcium), fiber, and antioxidants like beta-carotene.
