White Wake Robin (White Trillium)

Trillium flexipes
Family: 
Liliaceae (lilies)
Description: 

The large size and nodding or horizontally spreading flowers help to identify this trillium. Flowers large, triangular, with white petals; sepals 3, narrow, green. Flower to 2½ inches across on a stem, either horizontal or drooping when in bloom. Blooms April-May. Leaves 3, heart-shaped, pointed, large, in a whorl, usually as broad as long, to 9 inches long, green but not mottled.

There are 7 species of Trillium in Missouri. Snow or dwarf white trillium (T. nivale) is uncommon, mostly in northeast Missouri. It's the smallest and earliest-blooming trillium in our state and often forms colonies. Green trillium (T. viridescens) lives mostly in the southwestern Ozarks and has green or yellowish-green petals, sometimes with a purplish tinge.

Size: 
Height: to 2 feet. This is the largest trillium in Missouri.
Habitat and conservation: 
Occurs on rich, wooded slopes and in bottomland forests, generally on east- or north-facing hills, and along streams, bottoms, and lower slopes of valleys and ravines. Trilliums are popular in shade gardens but are difficult to grow from seed. This has led to unethical collecting from the wild. However, many plants do not survive transplanting. Please be aware of the sources for your plants, and insist on nursery-grown plants from cultivated stocks.
Distribution in Missouri: 
Scattered in eastern and east-central Missouri. Look for it in our eastern counties and in counties bordering the Missouri River.
Status: 
In addition to "white trillium" and "white wake robin," this plant is also called "drooping trillium," which reflects the meaning of the scientific name.
Human connections: 
Some species of trilliums were used historically in herbal medicine, but the most common human use of these flowers is in gardening. Please don't collect from the wild, however. Instead, buy nursery-cultivated plants from reputable sellers.
Ecosystem connections: 
Trilliums use their leaves to produce energy to store in their rhizomes, so that they have strength to bloom again the next spring. Because trilliums only have 3 leaves, which are so close to the flowers, picking trillium flowers removes the plant's ability to feed itself.

  • Wake Robin (Trillium)

    Missouri has 7 species of trilliums, which are in the lily family. The "tri-" in the name means "three" and refers to the flower, which has 3 petals and 3 sepals, and the 3 leaves that subtend the solitary flower. The petal color varies in this species but is most commonly brownish or maroon.

  • Ozark Wake Robin

    This rare trillium grows in the shade typical of upland hardwood forests of the southern Ozarks of Missouri.

  • Flowering Dogwood

    A beautiful shrub to small tree with a straggling, spreading crown, Missouri’s official state tree presents lovely boughs of white inflorescences in springtime forests.

  • Eastern Redbud

    This shrub or small tree is distinctly ornamental in spring with small, clustered, rose-purple flowers covering the bare branches before the leaves.

  • Johnny-Jump-Up (Field Pansy)

    It's not our largest violet, but it's one of the most common. The coloration of these delicate-looking flowers often looks faded. Look for it in fields, meadows, glades, rights-of-way, disturbed sites and possibly your front lawn.

  • Dead Nettle

    Dead nettle and its close relative henbit are both common, weedy mints that, in early spring, can carpet wide patches of disturbed ground. These shallow-rooted plants pose few problems, however. Recognize dead nettle by the pyramidal look of its purple- or blue-tinted foliage.

  • Dutchman’s Breeches

    This spring wildflower is easy to identify. Notice its bluish-green, fernlike leaves, and its leafless stalks, from which dangle several white flowers shaped like old-fashioned knee breeches.
