''Trillium erectum'', also known as wake-robin, red trillium, purple trillium,〔Dickinson, T.; Metsger, D.; Bull, J.; & Dickinson, R. (2004) ROM Field Guide to Wildflowers of Ontario. Toronto:Royal Ontario Museum, p. 79.〕 Beth root, or stinking Benjamin,〔(Stinking Benjamin: A trillium that by any other name would smell so sweet ), adirondack almanack〕 is a species of flowering plant native to the east and north-east of North America. It is a Spring ephemeral, an herbaceous perennial whose life-cycle is synchronised with that of the deciduous forests where it lives. This plant grows to about in height with a spread of , and can tolerate extreme cold in winter, surviving temperatures down to . Like all trilliums, its parts are in groups of three, with 3-petalled flowers above whorls of pointed triple leaves. The leaves contain calcium oxalate crystals and crystal raphide, and should not be consumed by humans. The flowers are a deep red colour, though there is a white form. The flowers have the smell of rotting meat, as they are pollinated by flies. The plant takes its name "wake-robin" by analogy with the Robin, which has a red breast heralding spring. This plant has gained the Royal Horticultural Society's Award of Garden Merit.〔(【引用サイトリンク】url=http://apps.rhs.org.uk/plantselector/plant?plantid=1947 )〕 ;Varieties〔 * ''Trillium erectum'' var.
