Anyone know what type of flower this is?
We spotted it growing in the gravel in front of the observation platform at the
Sacramento National Wildlife Refuge in late-September.
After doing some research, I think it might be a type of willowherb or lessingia.

When I first saw it, I thought it was just an ordinary weed, but upon closer inspection I noticed the little pink flowers.
It just goes to show you that beautiful things can be found growing anywhere and everywhere!
