This plant is highly regarded both as a nutritious salad green and for its use in natural water purification systems. Native to Europe and Asia, Watercress has become naturalized in many parts of the world, particularly in cool, freshwater streams, rivers, and ponds.Watercress is characterized by its sprawling, mat-forming growth habit. The plant features hollow, branching stems that can grow up to 2 feet long, allowing it to float on the surface of the water or trail along muddy banks.

The leaves are compound, with 3 to 9 oval or rounded leaflets that are dark green, glossy, and slightly peppery in taste. The leaflets are attached to the stem by short petioles, giving the plant a lush, dense appearance.During the spring and early summer, Watercress produces small, white flowers arranged in clusters known as racemes. Each flower has four petals and is typical of the mustard family.

These flowers are not only attractive but also play a role in the plant's reproductive cycle, eventually giving way to small, elongated seed pods.Watercress thrives in full sun to partial shade and prefers cool, fresh, and continuously flowing water. It can be grown in garden ponds, streams, or other water features, as well as in containers with consistently moist soil. Overall, Nasturtium officinale 'Watercress' is a versatile and beneficial plant that offers both culinary delights and ecological benefits.

Its ease of cultivation and nutritional value make it a valuable addition to any garden, particularly those with water features or damp, cool conditions.
