I planted seeds that said Romain lettuce, The Quails came in right after I planted my garden and took their little dirt bath and made a complete mess of the bed... I planted broccoli next to the lettuce, however this plant took over the entire bed for the exception of the Roma tomatoes which were planted at the other end of the bed, it' so obvious it's not lettuce, but what could it possibly be? photo attached, has little white flowers with yellow middle
