Hydrophyllum macrophyllum, commonly known as the large-leaved waterleaf, is a perennial herbaceous plant in the Boraginaceae family. Native to North America, it thrives in moist woodlands and along stream banks in the eastern United States and Canada. The plant can reach up to 3 feet in height with a spread of about 2 feet. Its large, lobed leaves can grow up to 8 inches long and wide, and they are arranged alternately on the stem with a hairy texture on both sides. Hydrophyllum macrophyllum blooms from May through July, producing clusters of bell-shaped flowers at the top of its stems. Each flower has five petals that range in color from white to light blue or lavender. This plant prefers moist soil conditions but can tolerate some drought once established. It is an excellent choice for woodland gardens or naturalized areas, where it can spread freely by self-seeding. Native Americans have used Hydrophyllum macrophyllum for its medicinal properties, particularly as an anti-inflammatory agent for treating skin irritations, wounds, and sore throats. However, it should be noted that improper handling may cause skin irritation. Overall, Hydrophyllum macrophyllum is an attractive native perennial suitable for naturalized areas or woodland gardens. Its beautiful foliage and charming bell-shaped flowers, which bloom in spring, add beauty to garden landscapes. Moreover, it offers medicinal benefits when used properly under expert guidance.
