This year, 2013 the flowers were first notice in early June.
The plant has many meanings. From Christian legends it represents Mary's Tears during the crucifixion of Christ, a symbol of humility in paintings and/or a sign of Christ's second coming. The lily symbolizes life to Pagans.
Care should be taken not to ingest or allow animals to chew on this perennial as many references state that some parts of it are toxic.
