If grown within proper range of a Bee House (5 squares in any cardinal direction), a Fairy Rose will cause Fairy Rose Honey to be produced, increasing the honey base value from data-sort-value="100">100g to data-sort-value="680">680g. This is the most valuable type of honey, compensating for the poor profit margins on the flower itself.
Fairy Roses can be purchased from the Traveling Cart for data-sort-value="290"870–1,450g.
Fairy Roses have an equal chance of being one of six different colors. Fairy Roses of different colors will occupy different slots in inventory or chests. Six colors × four quality levels = 24 possible spaces used.
Despite not having a true red variation, Fairy Roses are used as a red dye in the dye pots.
Bugs
While it was intended for Fairy Roses to increase the chance for the Crop Fairy event, with code appearing to check for having at least one mature Fairy Roses on the farm by the end of a day to increase the chance by 70% (from 1% to 1.7%), this does not actually happen in game as that check is not valid.[1]

↑See Utility::pickFarmEvent in the game code for where it appears to check for a mature fairy rose using an internal flag, see Crop.newDay where it tries to set that flag, but incorrectly uses this.fullyGrown.Value and all of Crop to see that this.fullyGrown.Value is only ever set to true for a regrowable crop or a forage crop spawned outside the farm.
1.5: Fairy Dust recipe introduced. Iridium quality is now possible when using Deluxe Fertilizer. Bugfix for crop stages with Deluxe Speed-Gro + Agriculturist. Is now an option in the Garden Bundle.
