I would think that the Large-flowered Trillium doesn’t need too much presentation. But, for just in case, it grows up to 40 cm and bears a solitary, 3-petaled white flower with 3 green sepals. Usually the flowers will turn light pink before they fade. Some individuals have light pink flowers or green bands on the petals (a result of a phytoplasma infection).
Medicinal: The rhizome was used medicinally by the Native Americans mainly to treat menstrual disorders, but also for skin irritations, snakebites …
Nothing equals in the spring a white Trillium flowering or even better a carpet of Trilliums! – it should have a place in any woodland garden or shady corner; great started from seeds for woodland restoration projects.
Germination: Best sown fresh, or kept moist and allowed to follow the outdoor temperature cycles and sown in the spring. Germination is hypogeal: in the first season it will form just a root/small rhizome and the first leaf appears in the second year (see image in the gallery). Some seeds will emerge radicles and form a small rhizome by fall when kept moist storage; these will send up the first leaf in the coming spring. It needs 4-5 years to get to the flowering size, but otherwise it is not difficult to cultivate in part shade locations and medium moist, well drained substrates.
