It has been brought to my attention that the Desert Rose achievement has been changed this year. In this quick and short guide I will explain the changes and how to do the achievement now! Thanks for watching!
As I said in this video, the achievement is changed. It no longer requires the dress (which was the point of the video) even though it says so in the achieve text still. As explained in the video, you now buy the Spring Florist's Pouch and use that to plant the flowers :)
