Danica asked you for sap from the Eldergleam to revive the dead Gildergreen in Whiterun. Instead, Maurice convinced you to bring back a sapling. All is now well in Whiterun, except for one small thing. That sapling deserves to grow into a nice big healthy proper replacement for the dead tree you helped get rid of.
For those who followed the path of renewal in Blessings of Nature, but missed out on seeing the full size live tree in all its glory, this mod is for you. Now you don't have to choose the path of violence and destruction if you don't want to. Your sapling will now grow over the course of 6 in-game months from a tiny bud into a full bloom tree you and the city can be proud of.
Kynareth shall smile on you for your kind ways.
