Stinking Benjamin

Trillium erectum, also known as Wake-robin, red trillium, purple trillium, Beth root or Stinking Benjamin, is a spring-flowering perennial plant native to the east and north-eastern areas of North America. The flowers are a deep red colour, and the plant takes its name Wake-robin by analogy with the Robin, which has a red breast that heralds spring.
This plant grows to about 40 cm in height with a spread of 30 cm and can tolerate extreme cold in winter, surviving temperatures down to -35 C. The flowers have the smell of rotting meat, as they are pollinated by flies. The leaves contain calcium oxalate crystals and crystal raphide, and should not be consumed by humans.
