Detailed Information

Flower: Flower shape: 3-petals

[photo of flowers] Flower is 2 to 3 inches across, 3 white petals, usually with ruffled or wavy edges, and a pointed tip. The petal width varies greatly, from relatively narrow to almost as wide as long. In the center is a group of several yellow stamens. There are 3 green sepals that are shorter and narrower than the petals. Each plant has a single flower at the end of a 2 to 3 inch stalk that rises above the leaves. The flowers turn rosy pink with age.

Leaves: Leaf attachment: whorl Leaf type: simple

[photo of leaves] A single whorl of 3 leaves is at the top of the stem. Leaves are 3 to 6 inches long and wide, generally oval to egg-shaped with a sharply pointed tip and tapering slightly at the base. Deep veins radiate from the base of the leaf.


Large-flowered Trillium is the largest Trillium in Minnesota. It is long-lived but slow to mature—it can be several years between the time seed is germinated and the first flower blooms. The seeds are mostly spread by ants, which take the fruit to their underground homes, eat the fruit flesh and leave the seed behind. At one time Trillium was in its own Trilliaceae family, then moved to the Liliaceae (Lily) family, and is now back in its own family, renamed Melanthiaceae.

In the woods by the cabin in Pine County, Trillium are now plentiful, and this is the first year we see them almost everywhere. With the cool spring, this is also the first time they've stayed around for almost a month, giving the white blooms the time to change to pinks and purples.

We have quite a few of these growing through the woods here. The variety that I have seen have the flower under the leaves and the petals are curled back towards the stem. They also produce large clusters of red/orange berries at the start of September.
