Clover used to be an intentional part of the American lawn prior to WW2. It thrives in poor soil, fixes its own nitrogen and can survive drought conditions and was deliberately added to assist with the growth of the surrounding grass.

Once weed killer came to market post WW2, it wasn’t long before chemical companies successfully re-branded clover as a weed. Clover is a broad leaf plant and was unintentionally killed alongside the other “unfavorable weeds” so it was successfully removed from the picturesque perfect American lawn by chemical companies.
