Mysterious palms grow in the Rotunda of the Alberta Legislature

The tour guide who walked us around the Alberta Legislature had a lot of lore to share about the building and the people associated with it. However, nobody seems to know how these palm trees got started growing in the Rotunda.

Who put the palms in the "Ledge," as Albertans call it, is a mystery. There is no record of who planted the palms up there or when or why.
Meanwhile, though, they continue to thrive.
