Estimated Native Range
Summary
Persicaria nepalensis, commonly known as Nepal Knotweed, is a semi-deciduous perennial herb native to the moderate elevation Himalayas, tropical and subtropical Africa and Asia, and the Russian Far East. It typically grows to a height and width of approximately 2 feet (0.6 meters), forming a dense, bushy clump. The leaves are attractively variegated with a chevron pattern, and the plant produces small, pink to white flowers in elongated clusters during the summer months, which are moderately showy and attract pollinators.
Nepal Knotweed is appreciated for its ornamental foliage and its ability to fill in garden spaces as ground cover. It is often used in borders, rock gardens, and as an underplanting for taller perennials or shrubs. This plant prefers moist, well-drained soils and can thrive in both full sun and partial shade. While it is relatively low maintenance, it requires regular watering, especially in dry conditions. Gardeners should be cautious of its potential to spread, as it can become aggressive in favorable conditions.CC BY-SA 4.0
