Summary

Persicaria minor, commonly known as Pygmy Smartweed or Small Water Pepper, is a perennial herb native to moist habitats in Southeast Asia, including Malaysia, Thailand, Vietnam, and Indonesia. It thrives in wet lowland areas such as riverbanks, ditches, and canal sides. This plant typically reaches a height of 3 to 5 feet, featuring green, reddish-tinged stems and lance-shaped leaves. The pale violet flowers bloom in summer and are arranged in elongated, slender spikes that add a delicate touch to the plant’s appearance.

Pygmy Smartweed is valued for its culinary and medicinal uses, with leaves that can be used fresh or cooked in various dishes. It is also appreciated for its ornamental qualities, particularly in water gardens or as a ground cover in moist, shaded areas. In cultivation, it requires consistently moist soil and can tolerate partial shade to full sun conditions. While it is not particularly drought-tolerant, it can thrive in poorly drained soils. Gardeners should monitor its spread in non-native regions to prevent it from outcompeting local flora.CC BY-SA 4.0
