Lythrum acutangulum, commonly known as Sharp-angled Loosestrife, is an annual herb native to the Mediterranean Basin, specifically thriving in wet meadows, marshes, and along stream banks. It is often found in these riparian areas, usually on clay soils. This plant typically grows to a height and width of 1.5-3 feet (0.46-0.9 meters), forming a bushy clump. The Sharp-angled Loosestrife is characterized by its upright stems and lance-shaped leaves, with pink flowers that bloom in the summer and are moderately showy, attracting pollinators such as bees and butterflies.

In cultivation, Sharp-angled Loosestrife is valued for its ability to thrive in wet conditions and is often used for naturalizing in water gardens, rain gardens, and other moisture-rich environments. It does best in full sun or part shade and prefers medium to slow-draining clay soils, with high amounts of water. While it is not commonly used in formal garden settings, its ease of maintenance and tolerance for wet soils make it a useful plant for challenging damp areas. Gardeners should be aware that Lythrum acutangulum can be potentially invasive in some regions outside its native range, and it is advisable to check local regulations before planting.CC BY-SA 4.0
