Stachys angustifolia, commonly known as Narrowleaf Hedgenettle or Stiff Hedgenettle, is a perennial herb native to the western United States, particularly found in wetlands, riparian zones, and moist meadows. It grows at a moderate rate to a height of 1.5-2.5 feet (0.46-0.8 meters) and a width of 1-1.5 feet (0.3-0.5 meters). This plant forms clumps of erect stems with narrow, lance-shaped leaves and produces dense spikes of purple flowers that are quite showy and bloom in the summer.

Narrowleaf Hedgenettle is valued for its attractive flowers and ability to attract pollinators such as bees and butterflies. It is often used in naturalized plantings, rain gardens, and as a border in moist garden areas. It thrives in full sun to part shade and prefers medium draining loam or clay soils, with consistent moisture. While it is adaptable to various soil types, it does not tolerate drought well. There are no widely known cultivars of this species in the horticultural trade, and it is generally grown from seed or division. Potential problems include susceptibility to rust and mildew, especially in humid conditions. It is not known to be invasive and is considered a beneficial native plant in its natural range.CC BY-SA 4.0
