Flower Fields is a plain in the northwest area of the Mushroom Kingdom in Paper Mario. It is home to the Bub-ulbs and the location of the sixth Star Spirit, Klevar. The only way Mario can enter Flower Fields is to go through a magic door in Minh T.'s garden unlocked by the Magical Seeds. Upon arrival, Mario finds Flower Fields dark and cloudy, learning that it is under attack. Huff N. Puff and his minions plan to cover the meadows in clouds and prevent the Sun from shining on the fields, causing Flower Fields and its Bub-ulb and flower inhabitants to slowly wither. Throughout Chapter 6, "Dark Days in Flower Fields", Mario and his partners explore around the Flower Fields, doing the flowers favors and getting items in return. Lakilester comes and joins Mario's party at one point. Finally, Mario grows a beanstalk with the Magical Bean, Fertile Soil and Miracle Water collected on the way and uses it to climb up to Cloudy Climb, where he defeats Huff N. Puff and saves the Star Spirit.
Flower Fields has a main hub with three paths on each side leading to various areas. The center hub also contains the vine that leads to Cloudy Climb, Wise Wisterwood, and a naughty flower named Tolielip that gives false information. Wise Wisterwood, the eldest tree in the fields (and most likely the elder of the fields), serves as the portal to Toad Town.
The paths that sprout from the hub:
Flower Fields is the only area in the game devoid of a Heart Block, Toad House, or any other form of instant healing. It is also the only area with Amazy Dayzees, a kind of enemy that drops a lot of Star Points.
The Magical Seeds are indeed the only way to get to Flower Fields; according to the map, the area is surrounded by mountains. This area also does not have a Warp Pipe leading to it.
In addition to the items dropped by enemies, overworld items found in this area include:
