Red Wake-robin - Trillium erectum
It has a very unique color, maroon almost the color the dark blood, the flowers are pollinated by
flies attracted by the color and smell.  
Supposedly ill-scented but I haven't really noticed any distinct smells coming from it.  I have
seen two types of this plant a small one only about a foot tall and a really large one about two
foot tall.  The two types are distinct as I have both and they keep coming back true year after
