Stachys tenuifolia, commonly known as Smooth Hedgenettle, is a deciduous perennial herb native to moist meadows, stream banks, and open woodlands in the Eastern and Central USA, as well as Ontario. It typically grows to a height of 1-3 feet (0.3-0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). The plant features a clumping form with square stems and opposite leaves, which are characteristic of the Lamiaceae family. It produces an array of tubular flowers that range in color from pink to white and purple, blooming in late spring to early summer. The flowers are modest in size but can be quite showy en masse.

Smooth Hedgenettle is valued for its ability to attract pollinators such as bees and butterflies, making it a beneficial addition to wildlife gardens and naturalized areas. It is commonly used in border plantings, cottage gardens, and as part of pollinator-friendly landscaping. This plant thrives in a variety of soil types, provided they are well-drained, and it can tolerate both full sun and partial shade. While it prefers moist conditions, it is relatively drought-tolerant once established. Gardeners should be aware that in optimal growing conditions, Stachys tenuifolia can spread vigorously, potentially becoming aggressive in garden settings.CC BY-SA 4.0
