Who could imagine that underneath the beautiful Snapdragon flower lurked such a macabre sight. These little skulls are the seedpods of the Snapdragon. They contain the flower seeds and are, apparently, rather difficult to break open, like real skulls would be I’d guess.
Snapdragons are so named because they are said to look like dragon faces, and, after all, every face needs a skull.

Yes, they do look just like skulls!
