Trillium grandiflorum, the white trillium, great white trillium flower 2024

Trillium grandiflorum (white trillium, white lily, wakerobin) flowers in Apr-May in hardwood forests of western and central Québec and in the lower Ottawa Valley, ON. It has been the Provincial Floral Emblem in Ontario since 1937. The roots were valued for their astringent and antiseptic properties.

It is not advisable to pick the flowers, as it can seriously injure the plant and it can take years to recover from the damage. In an optimal setting, it can take a single trillium seven to eight years to produce a flower. If conditions aren't the best, then it may take upwards of 10 years! Slow and steady wins the race in the genus Trillium.
