Summary

Hydrophyllum macrophyllum, commonly known as Largeleaf Waterleaf, is a deciduous perennial herb native to rich, moist deciduous forests and floodplain woodlands in the Southeastern United States. It typically grows to a height and width of approximately 0.5 feet (0.2 meters). The plant features large, lobed leaves and clusters of small, bell-shaped cream flowers that bloom in late spring to early summer. The flowers are not particularly showy but add a delicate texture to woodland gardens.

Largeleaf Waterleaf is valued for its foliage and its ability to thrive in shaded conditions, making it an excellent ground cover for woodland gardens and shaded borders. It is also used for naturalizing in moist, shady areas. This plant prefers part shade but can tolerate full shade, and it requires consistently moist soil with good drainage. While it is not drought-tolerant, it can adapt to drier conditions once established if mulched well. Gardeners should be aware that it can self-seed and spread, which is beneficial for naturalizing but may require management in more formal garden settings.CC BY-SA 4.0
