Weekly Puzzler Answer #137

rowan-0013Did you recognize the stalk with bright red berries from last week’s puzzler? These are the berries from a plant called Jack in the Pulpit, or Arisaema triphyllum. Have you seen it? It looks like this:

m3-4435 m3-7067

This plant has the rare ability to change its sex based on the area where it grows. It may live for 20 years and can change again and again and again. When it has the right nutrients and moisture and has reached a sufficient size to provide resources to support a flower and fruit, it will be female. When it lacks nutrients, it reverts to a male plant. A jack that makes male flowers has only one main leaf whereas a female has two.

m3-0009

Since it has only one leaf, it is a male.
