Trillium decipiens
deceptive trillium
Southeastern United States (Apalachicola basin)
Attracts Pollinators
Native to North America
Overview
Trillium decipiens is a spring-flowering, rhizomatous woodland perennial in the bunchflower family, growing 12–20 inches (30–50 cm) tall from a single upright stem. Three broad, mottled leaves are held in a whorl at the top of the stem, patterned in silver-green, dark green, and maroon that fades as the leaves age. A single stalkless (sessile) flower sits directly on the leaf whorl, with three erect, narrow petals 1.5–2.5 inches (4–6 cm) long in dark maroon to brown-purple. It is a sessile-flowered trillium, so the flower does not nod on a stalk. The plant emerges in late winter to early spring, flowers, then dies back to the rhizome and goes dormant by midsummer. It grows in deciduous woodland in deep, humus-rich soil and deep to partial shade. Growth is slow from seed, taking several years to reach flowering size, and the dormant rhizome leaves bare ground for much of the year.
Native Range
Trillium decipiens is native to the southeastern United States, in the Apalachicola River basin of Georgia, Florida, and Alabama. It grows in rich, shaded hardwood forests and on wooded ravine slopes.Suggested Uses
Trillium decipiens is used in shaded woodland and native plant gardens, among ferns and other spring ephemerals, spaced 8–12 inches (20–30 cm) apart. It suits naturalistic plantings under deciduous trees. Its summer dormancy and slow growth make it less suited to formal beds that need year-round cover.How to Identify

Reaches mature size in approximately 7 years
Bloom Information
Flowering occurs in early spring, roughly March to April, soon after the mottled leaves unfurl. The single sessile flower holds its erect maroon petals for two to three weeks. The plant sets seed and then dies back to the rhizome, going dormant by midsummer.

Care & Maintenance
Care Guide
Trillium decipiens grows in deep to partial shade and moist, humus-rich, well-drained woodland soil with a pH between 5.5 and 7.0. A mulch of leaf litter keeps the soil cool and moist and feeds the rhizome. The plant emerges in late winter, flowers in spring, and goes dormant by midsummer, so the ground is bare for much of the year. It is sensitive to disturbance and slow to establish, taking several years from seed to flowering size. The rhizome is planted with the growing point a few inches deep. Dry soil and full sun shorten its life.Pruning
No pruning is needed. The foliage is left to die back naturally after flowering, as it feeds the rhizome for the following year. Spent flower and leaf stems can be cleared once they have withered.Pruning Schedule
