Pseudotrillium rivale

I have seed raised plants of this small woodlander they are 4 years old and most will flower next year. As with all trillium it requires cool moist conditions in partial or full shade. Once established this plant will self seed lightly and develop into good big clumps. Its cultivation as a garden plant would be restricted to cooler parts but I think if grown as a potted plant it could survive in warmer gardens.
