One of the earliest spring bloomers, this six-inch-tall beauty slowly forms a carpet of mottled foliage and delicate downward-facing blooms. The blue-green leaves streaked with purplish-brown markings are similar to those of several other species, but the flower's flaring, white tepals set this trout lily apart from the rest. White trout lily blooms mid-April through May, nearly one to two weeks before yellow trout lily, in most counties in Ohio. Huge colonies of mostly non-flowering individuals can cover the forest floor; an especially large population is located in Stages Pond State Nature Preserve. Often found in mature, wooded floodplains, white trout lily requires moist, well-drained soil that's rich in organic matter. It will not tolerate heavy clay. Plant it under deciduous trees that provide full shade in summer during the plant's dormancy.
White trout lily and other spring flowering plants are unsung heroes that keep woodlands thriving. In 1978, Robert Muller theorized that, without plants, soil nutrients would be washed away during spring snow melts. And recent studies are substantiating Muller's "vernal dam hypothesis." Spring ephemeral's superpower is the ability to grow and thrive in lower temperatures. They partner with an extensive mychorrizal (fungal) network to absorb nitrogen, phosphorus, and other nutrients. The plants store the essential elements in tiny reservoir pockets in their tubers, roots, and stems until they begin to go dormant in mid-summer, whereupon they release their pocketed nutrients into the soil to enrich their late-blooming neighboring plants.
Native habitats include woodlands with moist, well-drained soils; banks of streams; and slopes of ravines. Use in woodlands, pollinator gardens, and naturalized areas. Try pairing with ferns and other shade-loving plants. Plant the corms about 4” deep and apart.
Plant Characteristics:
Grows 4-8" tall.
Prefers full or part shade.
Prefers moist, rich soils. Will not tolerate heavy clay or dry soils.
A single flower nods at the end of a stiff stalk up to 8" long. White, purple-tinged flowers have 6 lance-elliptic tepals (3 petals and 3 similar sepals) up to 1½ inches long. Center has 6 long stamens with bright yellow tips (anthers). Flowers open in the morning, the tepals flaring out and back, and close at night. Oval fruit capsule is 3/8 to 1" long.
Reproductive System: non-flowering plants reproduce via stolons buried just below the surface that forms a new bulb at the end, from which a new shoot emerges the following year.
Lance-elliptic to oval-shaped leaves are all basal. rising on a slender stalk from an underground bulb. Smooth-edged leaves are 3-9" long, hairless, and tapered at both ends. Flowering plants have a pair of leaves and non-flowering plants have a single leaf. The mottling typically fades with age.
Wildlife Value:
A specialist miner bee, Andrena erythronii (trout lily mining bee), depends upon the pollen to feed its young. The flowers attract long-tongued bees, blowflies, and butterflies, including sulphurs and whites. The leaves and seed capsules are browsed by deer to a limited extent. The corms are a mainstay of the chipmunk's diet.
Medicinal, Edible, and Other Uses:
Iroquois women ate the leaves as a contraceptive, and Cherokee chewed the root and spit it into water to attract fish. A medicinal tea was used to treat fevers, ulcers, and swollen glands. One source indicates that skin contact with the corms has been known to cause dermatitis in sensitive individuals.
The bulbs have been ground into powders in Europe and Japan to use in candies, sauces, and other dishes. The mild-flavored leaves and slightly sweet flowers can be used in salads. The flowers, leaves, and corms can be used to make tea.
The bulbs were considered to be an aphrodisiac by 17th century Europeans.
Caution: trout lily is an emetic; avoid eating large amounts at one time.
