This is another photo taken at Summer Lake in Skagit County, Washington, where someone has planted different non-native species of carnivorous plants that have become naturalized there. We go every year to see these, but usually go in October. Since we were earlier this year we were able to see these flowers still in bloom. The Purple Pitcher Plant is Sarracenia purpurea and is native to the eastern United States. The plant is shown below.
