Location

Found in common area at the bottom of my property. Common area is a wetland area. There is a large oak tree with Russian irises around the base. Noticed one plant 2 years ago, it was smaller at the time and I removed it. ( didn’t know what it was).
There are now several smaller plants among the irises.
There is one large plant that showed up this year. Will send a picture.

Thank you.
