Summary

Persicaria mitis, commonly known as Mild Water-pepper, is a perennial herb native to a variety of habitats across Europe, including riverbanks, damp meadows, and marshy areas. It is often found in wet, fertile soils where it forms dense stands. This plant typically grows to a height of 20-70 cm (8-28 inches) and has a spreading habit. The leaves are lance-shaped with a characteristic reddish-brown blotch in the center. Persicaria mitis blooms from late summer to early autumn, producing small, pinkish-white flowers that are arranged in slender, elongated spikes. While not particularly showy, the flowers are attractive to pollinators such as bees.

Mild Water-pepper is valued for its ability to thrive in wet conditions and is often used in rain gardens, water features, and as a ground cover in damp areas of the garden. It is relatively low-maintenance, requiring consistently moist soil and partial to full sun exposure. It is not commonly afflicted by serious diseases or pests, but can occasionally suffer from rust or mildew in poor air circulation or overly dry conditions. Gardeners should monitor its growth in non-native regions to prevent excessive spread.CC BY-SA 4.0
