Another reward for not weeding

Well, it happened again.... I didn't keep up with the weeding and all of a sudden there were flowers! Right in the middle of my circle of hose. I have no clue what is planted where, and no idea what some of this stuff looks like when it's first starting, so when I do weed (once or twice a season whether the garden needs it or not) I just pull everything that doesn't have a flower attached. I wonder what I have destroyed?!
