This plant is growing in the spot that used to be my pond. Don't know where it came from but it is already about 3 ft. tall. Attaching a picture of it.
The leaves are spade shaped and toothed at the edges. The younger leaves are more heart shaped. In the picture you can see spike type buds? at the tops. Not sure if this is the start of a flower that will eventually open up.
Can anyone identify this plant?
Do get rid of these before they flower and set seed. Happily, they can be pulled up roots and all pretty easily. Have you heard the saying, "one year's seeding, seven years weeding"? So true with this plant pest.
Thank all of you...Malus2006, altagardener, and wandygirl...I believe you are all correct. Since it is so very invasive, I guess it will be leaving that location tomorrow.
I had other ideas for that spot anyway...wanted to make it a rock garden and put some other types of plants there. This one just showed up and till now filled in and looked pretty to me. But, I don't want anything that is considered invasive so it's gotta go. I don't see any others like it on my property, so I guess that is a good sign.
