Arisaema fargesii

Cobra Lily | Excellent, superb, and other incredible descriptive words are all that can be said about this plant.  Cold hardy to zone 5 this cousin to our native Jack in the Pulpits has very large glossy leaves that emerge in spring.  Take a peak inside the foliage and you will see the flowers that resemble a cobra with its hood spread out.  Over the years this plant will form a stunning mass in the garden that will be one of your favorite things to show off to your friends.
