Water Spinach

Water spinach is a semi-aquatic leafy green widely used in Southeast Asian cuisines. Despite its name, it’s not related to common spinach — it belongs to the morning glory family and has a distinctive hollow stem that stays crunchy when cooked.

The leaves are tender with a mild, slightly sweet flavour, while the stems provide a satisfying crunch. It’s a staple in stir-fries, particularly the classic garlic and chilli preparation found in Thai, Vietnamese, and Malaysian cooking. It also works well in soups, curries, and simply blanched with oyster sauce.

Water spinach is increasingly available at Asian grocers and farmers’ markets across Australia. It wilts quickly after purchase, so it’s best used within a day or two. Both the leaves and stems are eaten, though they’re often separated during preparation since the stems take a little longer to cook.

How it's made

Water spinach is grown in wet, tropical conditions — either in waterlogged soil or semi-hydroponically in shallow water. The leaves and stems are harvested together by cutting the plant above the base, which allows it to regrow for multiple harvests through the growing season. After cutting, the greens are bundled and sold fresh.
