Tanna,

It is Chamberbitter, also known as Little Mimosa or Gripeweed (Phyllanthus urinaria L.). Linked below are lots of articles about controlling this weed. I know how frustrating tough weeds can be - good luck!

A preemergent in the flower beds will help prevent it but you will still have it in the lawn.

I heard that it was called summerweed. I have made my peace with it though I do work to pull them when still small.

Thank you so much for the information. I've done a little research since I now know what this is called. UF recommends thick mulch since the seeds require light for germination which makes sense. Explains why they only seem to be in certain areas and I do need more mulch in these beds. I think I will pull out what i can and then cover everything with lots of newspaper and mulch at least 3" or more. Maybe that will help. Sure won't hurt.

Thanks again!

That stuff is horrible. I've resigned myself to having to tolerate it.

I find that I really only have a problem with this type of weed in the beds where the mulch is thin. On the beds that I've recently put in new mulch, usually at least 3" thick, I only find the growing out of the bases of plants where the mulch is thinner. It's pretty easy to pull by hand, especially if you use a digging fork first to lossen up the soil in the area.
