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: Identification of Sagittaria-like plant with purple flowers
Answered by: Nan Hampton

QUESTION:

I have collected a wetland plant that I can't seem to identify. Its an emergent plant collected along with a species of sagittaria. Very similar in leaf structure to an sagittaria or alisima, but it has purplish/blue flowers. Any Ideas?

ANSWER:

I think your plant is probably Pontederia cordata (Pickerelweed).  Here are more photos and information from the Virginia Tech Weed Identification Guide and Illinois Wildflowers.
