Common Name:
Watercress
Description:
Watercress is a fast-growing, semi-aquatic leafy green herb prized for its crisp texture and distinctive peppery flavour, making it a popular addition to salads, sandwiches, and garnishes. This nutrient-rich plant produces small, rounded green leaves on succulent stems and thrives in consistently moist to wet conditions, often grown in shallow running water or damp soil. In Melbourne’s climate, watercress performs best in a cool, partially shaded position with access to clean water, and it can be grown successfully in pots, water features, or garden beds kept consistently moist. It grows vigorously through the cooler months of spring, autumn, and mild winter periods, with flowering typically occurring in warmer conditions. Regular harvesting encourages fresh, tender growth and helps prevent the plant from becoming leggy or overly bitter.
