Thanks, gentlemen. I'm amazed that I didn't find the primrose on the TAMU site......just looked at the first picture, and it doesn't at all resemble my plant. So, I just blew it off and went on searching...Duhhh !
I suppose I'll watch the plants this summer and make a determination in the fall. I do not have much shallow water at all, so maybe the primrose won't be a problem. Just want to make sure folks can still fish from the banks. Maybe with Rodeo, I can keep the sedge to a managable, small portion of the shoreline. Thanks, again.
