Trillium chloropetalum var. giganteum, commonly known as Giant Wakerobin, is a deciduous perennial herb native to the rich, moist, deciduous and mixed evergreen forests of Northern California. It typically grows to a height and width of 1-2 feet (0.3-0.6 meters). The plant is noted for its mottled leaves and large, showy flowers that can vary in color from brown, yellow, green, purple to red, blooming in early spring. The flowers are often followed by berry-like capsules that provide food for wildlife.

Giant Wakerobin is valued for its striking flowers and is used in woodland gardens, shade gardens, and native plant landscapes. It is a low-maintenance plant that adds a dramatic touch to shaded areas. While it prefers humus-rich, well-drained soil, it is adaptable to a range of soil conditions as long as adequate moisture is provided. It is best grown in part shade to full shade and requires consistent moisture during the growing season. Over-collection and habitat destruction have led to its decline in the wild, making cultivation in gardens increasingly important for its conservation.CC BY-SA 4.0
