Purple trillium, wake robin
Native to the Finger Lakes Region, Eastern N. America
A 10-12" tall plant with stalked, dark red, nodding flowers.
Light: shade to part sun
Moisture and Soil: medium moisture, rich soil
Seed Treatment and Storage: Keep seeds moist. Needs warm+moist/cold+moist stratification. It may be 2-3 years until growth appears above ground (first year post germination is underground development); 5-8 years to flower.
Although it has been recorded that young, unfolding trillium plants can be eaten, these scarce and precious wildflowers should not be gathered for food purposes except in cases of emergency. Trillium roots are highly emetic. The Cherokee used wake robin for everything from bowel complaints and profuse menstruation to asthma and coughs. The Abnaki prescribed ground rhizomes for a variety of pediatric maladies, and the Haudenosaunee combined the underground parts with other plants in a remedy for pimples and sunburn.

Because wake robin flowers have the color and appearance of rotting meat, they probably attract flesh flies, carrion beetles, and similar insects. Trillium seeds are dispersed by ants, who take the fruit to their underground homes, eat the flesh (elaiosome) and discard the seed. The foliage is vulnerable to browsing by white-tailed deer.
Climate change sensitivity

USDA Hardiness Zone
This trillium's blood-red flowers produce a mildly unpleasant smell to attract pollinators, hence its other common name, "stinking Benjamin."
