I guess it's also called giant trillium, or Trillium chloropetalum, but why say trilium when you could say wakerobin? First one I've seen in bloom this season
2010.06.12: Lower Austria, Bruck/Leitha (broadleaf forest, 220 m AMSL).Almost grown up, and showing buds already.German name: Schwarz-GermerID: see remarks here; still not flowering but even so it becomes more obviousy by each week that ID has to be correct.
