Poppies

From Oz Wiki

Poppies are beautiful scarlet flowers with a spicy scent. There is a meadow full of them in the Munchkin Country of the Land of Oz, and the odor of the poppies there is so powerful that anyone who breathes it falls asleep and could sleep on and on forever.

[edit] History

In Dorothy Gale's first visit to Oz, she succumbed to the scent, along with Toto and the Cowardly Lion. The Scarecrow and Tin Woodman rescued Dorothy and Toto, and the Cowardly Lion was rescued by Field Mice.
