Outstanding Qualities

In early spring this easy to grow trillium emerges from the soil with leaves mottled chocolate, green and mint. As the foliage mature the mottling will fade, but remain showy through the growing season. The flowers can vary from deep maroon red, intense browns and bright chartreuse green. This is one of the most robust of the eastern US native trilliums and well worth planting for its subtle beauty and unusual flower color.

Culture Notes
This trillium grows best in rich moist to well-drained soils, although it will tolerate sandy sites and clay. Plant it in a location with light to open shade. Once established water at least occasionally (every 10 to 14 days) during dry weather, but it will do better if watered regularly (once per week). Often this perennial will go dormant in summer.
