Trillium grandiflorum aka Great White Trillium

Taxonomy ID: 9494

Trillium grandiflorum, also known as the white trillium, large-flowered trillium, great white trillium, white wake-robin, or trille blanc, is a species of flowering plant in the Melanthiaceae family. It is a monocotyledonous, herbaceous perennial that is native to eastern North America, ranging from northern Quebec to the southern parts of the United States. It can be found in rich, mixed upland forests and is easily recognized by its attractive three-petaled white flowers that bloom from late spring to early summer, rising above a whorl of three leaf-like bracts. The plant is an example of a spring ephemeral, meaning its life-cycle is synchronized with that of the deciduous woodland. The white trillium often occurs in dense drifts of many individuals and is renowned for its extensive stand in the G. Richard Thompson Wildlife Management Area in the Blue Ridge Mountains. Over a two square mile area along the Appalachian Trail near Linden, Virginia, there is a spectacular annual display of white trilliums estimated at near ten million individuals. Great White Trillium, a super rare houseplant, is a member of the Trillium genus and is native to Eastern North America. It is not challenging to grow and requires regular watering to thrive. It does best in abundant sunlight and should be less than 3 feet from a window. The plant prefers soil that is well-draining and does not typically require added fertilizers if repotted each time it doubles in size.
