Sarracenia flava is known as the yellow pitcher plant due to its striking and vivid yellow coloration. The slender pitchers of Sarracenia flava attain heights of up to 3', and have a rigid, sturdy structure.
The Sarracenia flava rugelii variety has a deep red blotch on the throat of each pitcher. This blotch is often covered in tiny droplets of nectar, and it's theorized that this serves to attract certain prey insects. The rest of the pitcher is bright yellow, and has little or no veins or dark coloration. Sarracenia flava var. rugelii also have characteristically large lids, and produce large numbers of pitchers each growing season.
