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


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?


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.
