Question
This plant has come up along with many poppies I started from a bag of mixed poppy seeds in my garden in Indianapolis. It is now over five feet tall and blocking the view to the rest of the poppies. I'm hoping it might be a prickly poppy, but when answering the plant identifier questions I came up with a field sow thistle. Neither plants' stock pictures seem quite right. Any help would be greatly appreciated! Pull it or leave it?
Answer
Dear Sdixon00, your plant is likely Lactuca serriola (prickly lettuce), a wild plant that can be found in human-disturbed habitats. It will exude a white latex from any wounds that are made. Best wishes.
