Trillium pusillum

Trillium pusillum is a species of flowering plant in the family Melanthiaceae known by the common names dwarf wakerobin,[2] little trillium and dwarf trillium.[3][4] It is native to the southeastern and south-central United States from Oklahoma to Maryland.[1][5]

This is a perennial herb with a thin, branching, horizontal rhizome. It produces one or two slender scapes up to 20 centimetres (7.9 in) tall. They increase in size after flowering. The three bracts are dark green, sometimes with a red tinge when new. The flower has three green to red-tinged sepals up to 3 centimetres (1.2 in) long and 3 wavy-edged petals which are white and quickly age pink. The 6 stamens are tipped with lavender or yellow anthers each up to a centimeter long. The stigmas have long, narrow, spreading lobes. The pulpy fruit is 1 to 1.5 centimeters long.[3]

Trillium pusillum can be found in several habitat types, including savannas, swamps, bogs, forests and woods, and fields. It grows on acidic soils.[1] It is commonly pollinated by the western honey bee (Apis mellifera), and the seeds are dispersed by ants and harvestmen.[6]

Trillium pusillum has been divided into several varieties. Some authors accept only two, var. pusillum and var. virginianum.[3] The var. texanum is now treated as a separate species, Trillium texanum.[1]
