Sam is a steady and reliable character in the book. He is very practical, loyal and has a huge role to play in the war of the ring. He starts out as Frodo Baggins gardener and eavesdrops on his conversations with the wizard Gandalf. As his punishment Gandalf gets him to accompany Frodo when he seeks out Rivendell. Sam joins the fellowship of the ring at Rivendell and accompanies the ring-bearer Frodo all the way to Mordor to the very heart of Sauron's realm, at the volcano of Mt Doom. At times he literally carries Frodo away from danger. He also briefly bore the ring of power and helped to tame Gollum, a wretched creature who has a pivotal role in the story. Sam returns to the Shire after the war and plants up trees to replace those chopped down during the war. He plants a seed from the mallorn trees of Lothlorien, gifted to him by Galadriel. This becomes the only tree of this species west of the Misty Mountains. Sam marries his sweetheart Rose Cotton and settles with Frodo at Bag End. Sam and Rose have 13 children. Their first daughter was called Elanor after a small flower growing in Lothlorien. Sam becomes Mayor of the Shire for many years.
