Hi, thanks for the question. Always nice to have a challenge late in the evening.

This is the dreaded Prostrate Knotweed (Polygonum aviculare). It rears its ugly head during late July and August. It is an annual plant which means it will die off within the next six weeks or so. But prior to doing so, it will release an unbelievable number of seeds that will be dispensed by wind and birds. These seeds will then subsequently germinate spring 2023. If you look closely at it, you will see its characteristic red stems. See:

Thanks for your response.  Annoying is always in the mind of the beholder.  Thanks again for your thoughts.
