Trillium grandiflorum, commonly known as the large-flowered trillium, is a perennial wildflower native to eastern North America. It typically grows in rich, moist woodlands and is recognized for its striking white flowers, which can turn pink as they age. The plant features three broad leaves that form a whorl at the top of a single stem. This species blooms in early spring, attracting pollinators like bees. Trillium grandiflorum is also significant in traditional medicine and is often used in landscaping for its aesthetic appeal. However, it is important to protect its natural habitats, as it can be threatened by habitat loss and overharvesting.
