These seeds covered the yard last year to. Only this year, the conditions must be perfect because they have turned into this:
You can even see them coming up in the lawn. I have no clue what they are, but I know I do not want them. I have been weeding every day for at least 30 minutes for almost two weeks, but I still have not gotten rid of them. They are so thick and there are so many seeds that I am getting rid of them as they sprout, but they are beating me. Lovely excuse to be outside when it not raining though!
