Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Arisaema triphyllum as an insect eater
Answered by: Damon Waitt

QUESTION:

Is the Jack in the Pulpit an insect eater?

ANSWER:

No, but it is pretty easy to see how the spathe (a large, cylindrical, hooded flower) of Arisaema triphyllum (Jack in the pulpit) (pictured right) could be confused with the pitcher of the insectivorous Sarracenia alata (yellow trumpets) (pictured left). Water collects in these "pitchers" and insects are trapped, decomposed, and partially absorbed by the plant.
