Tangerine Trees

Tangerine Trees, or Mikan trees, is a tree which grows tangerines (or mikan, depending on the translations). If you look at the picture of the Going Merry, you'll find a huge bush with Tangerines on the top end of the ship. These are Tangello, but usually translated as Tangerine or Orange. These trees are taken very dearly by Nami. They provide the crew with Vitamin C as well as some decor on the ship.

When Nami departed from her village, she took 3 Tangerine Trees with her as a memento of Bellemere. Nami does not want anyone eating the Tangerines from the tree, aside from Nami taking care of them, Sanji also protects these three trees from those who might otherwise harm them or steal the fruit, like Luffy. During Water 7 arc, when the crew abandoned the ship, Nami took the trees and moved them to the hotal storage house. After the Enies Lobby Raid, Nami thought all of the crew's belongings and her Tangerine Trees were washed away by the Aqua Laguna, Nami then went into a deep depression. But in reality, the locals seized their belongings and kept them for themselves but when they learn of the truth about the Assassin attack against Iceburg, they returned the belongings including the Tangerine Trees, Nami happily hugs them.

They, along with the rest of the Straw Hats' stuff, now reside in a little area on the top of the kitchen and dinning hall of the Thousand Sunny that mimics the area ontop of the Going Merry, together with Robin's flower garden, the chimney for the kitchen below, and the office branch for Usopp's Factory.
