Trillium oostingii
Also called Wateree River Toadshade, Oosting's Trillium
Trillium oostingii is a rare spring-flowering woodland herb native only to central South Carolina, forming colonies in rich floodplain forest. It is a rhizomatous wildflower that needs cool, moist, shaded conditions and is best left to native-plant specialists rather than grown as a typical garden plant.
Trillium oostingii, commonly known as Wateree trillium, is a species of flowering plant in the family Melanthiaceae. It is endemic to the central part of the US State of South Carolina. Wateree trillium grows under a canopy of deciduous trees such as bitternut hickory, black walnut, slippery elm, box-elder, and various oak species, in rich floodplain soils. Here it forms large colonies alongside mayapple, another spring-flowering herb.
Wateree trillium most closely resembles the sessile-flowered trilliums, T. lancifolium and T. recurvatum, but is distinguished from these chiefly by floral anatomy. In T. oostingii, the anthers are only slightly incurved (curved toward the center of the flower) and have much shorter filaments, resulting in a more compressed look. According to DNA sequence analysis, T.
