Trillium viridescens, commonly known as Ozark trillium or tapertip wakerobin, is a perennial herb native to the understory of rich, deciduous forests in the Ozark Mountains and surrounding regions, including parts of Arkansas, Missouri, Oklahoma, Kansas, Texas, and Louisiana. It typically grows to a height of about 2 feet (60 cm). The plant is notable for its striking early spring blooms, which appear from early April to mid-May. The flowers feature unique bi-colored petals that are purplish near the base, transitioning to green towards the tips, and are quite showy, attracting early pollinators.

Ozark trillium is appreciated for its ornamental value, particularly its distinctive flowers that herald the arrival of spring. It is used in shade gardens, woodland plantings, and naturalized areas where it can form attractive colonies over time. In cultivation, it requires moist, well-drained soil rich in organic matter, mimicking its native forest floor habitat. It prefers part shade to full shade conditions and is relatively low-maintenance once established. However, it is important to note that Trillium species can be slow to establish and may take several years to flower when grown from seed. While generally pest-free, they can suffer from slug damage. Additionally, Trilliums should not be harvested from the wild due to their slow reproductive cycle and the risk of depleting natural populations.CC BY-SA 4.0
