About This Quiz

One of the naturally beautiful things that we humans have been blessed with is flowers. These plants have the power to convey feelings and emotions like love, pride and even lust. They can brighten someone's day or even bring hope- and they do these things while looking good. But as the saying goes, "all that glitters is not gold." Such is the truth for quite a few of these wondrous blooms. 

To explain our somewhat veiled statement, some flowers are extremely dangerous to the health of not only animals but that of humans as well. Some have the ability to paralyze, cause cardiac maladies and even death, and you need to know which ones they are. And that's exactly what we're going to test you on today. Do you have the know-how to identify some of the most poisonous plants on this planet just by looking at a picture? We're about to find out. 

We know that dogs should stay away from azaleas and delphiniums, cats from chrysanthemums and amaryllis flowers, and humans should stay extremely far from oleander and the rosary pea.
