I believe that the pansies’ height growth will be stunted the most after being exposed to one minute of cigarette smoke, followed by marigolds, and lastly followed by hollyhocks. In order to form my hypothesis, I researched pansies, marigolds, and hollyhocks. Source one stated that pansies are only hardy up to zone six. This causes me to believe that, of the three types of plants I am testing, pansies are the least hardy. Source two stated that marigolds are hardy. This is why I believe that the marigolds’ height growth will not be stunted as much as the pansies’ height growth. Source three stated that hollyhocks are hardy in our hardiness zone, zone eight. This tells me that the hollyhocks will be harmed the least.

good luck!
