Arnoglossum reniforme, commonly known as Great Indian Plantain, is a deciduous perennial herb native to moist meadows, prairies, and open woodlands in the Eastern and Central United States. It typically grows to a height of 3-9 feet (0.9-2.7 meters) and a width of 2-4 feet (0.6-1.2 meters). The plant features large, kidney-shaped leaves and a tall, unbranched stem topped with clusters of small, fluffy white flowers that bloom in late spring to early summer. The flowers are not particularly showy but do attract pollinators such as butterflies and bees.

Great Indian Plantain is valued for its bold foliage and architectural height in native plant gardens and restoration projects. It is used in border plantings, as a backdrop in perennial beds, and for natural landscaping. This plant prefers consistently moist, well-drained soils and can tolerate part shade, although it thrives in full sun. It is generally low-maintenance, but it may require staking in windy areas or if grown in overly rich soils. While not commonly afflicted by serious diseases or pests, it can occasionally suffer from rust or leaf spots. Great Indian Plantain is not known for aggressive roots or invasiveness, making it a safe choice for most garden settings.CC BY-SA 4.0
