Have you walked a forest floor filled with Trillium in bloom?  This plant is magnificant, especially en masse.  
 
     Trillium grandiflorum has one of the largest flowers of the native plants, and the flowers look especially beautiful against the backdrop of the deep green foliage. 
 
     Trillium is a spring ephemeral, blooming early and going dormant by mid summer.  Try it among ferns and other shade-loving plants.  Trillium grows naturally in the dappled shade beneath deciduous trees like Beech and Maple.
