Found a few of this plant in my lawn and they are able to regenerate much quicker than the grass, please help identify what it is

Hi mrnewbie, Welcome!

To my old eyes, the growth habit doesn't resemble that of Japanese Knotweed (Reynoutria japonica) but better photos will tell for sure. If it's possible, please upload a few more photos; it will help to see one showing the arrangement of the leaves along the stem, one showing a closer view of the leaves from the top and also a photo showing the stem. Have you pulled any of it up to see what the roots look like? My first thought was possibly emerging Kudzu (Pueraria montana) but when I enlarge the photo, I don't see the three leaflets typical of Kudzu.

Looks like Mirabilis...


Try digging up the tuber of one...


You may realize that you have something worth growing.

Oh, I take back my guess. I didn't scroll past the first picture. I think it is ruled out by these opposite leaves.. Could agree with Mirabilis.

I was told that if the plant regenerates really fast then it's likely to be weed. I normally mow the plant along with my lawn and if you take a look at my first pic, you'll see how much it grows over 1-2 week period compared with the lawn.

Dig one up. If it looks like that photo of Mirabilis, the bulbs will continue to return until something kills them, and seeds last a long time if they are allowed to bloom....at least in my zone.

Finding a tuber-thing will definitely ID it as Mirabilis. They can grow to the size of footballs - use your big shovel!

4 o'clock flowers tend to regenerate very fast from the existing tuber...
This doesn't make them weeds.... Very attractive to butterflies and hummingbirds and various other pollinators.

Suggest not mowing over the plants, and see if you don't get pretty flowers in a few weeks.

Thank you all, I'll dig one up when I get a chance.
