If you're willing to shell out the 3,000 Simoleons to purchase it, the item itself has a House Value of $2,350, and can be used to build up your Art Mastery. You don't need any ingredients to actually construct the hedge in your game, but you will need parts to unlock each Skill level, just as is the case with other Skill items in the game.
All told, you can use the Wonderland Topiary to add over 20 points to your Art mastery skill level, but of course, we won't blame you if you just want to purchase one because it looks cool. In addition, if you're able to master a new skill within the topiary, you'll receive a free Lush Hatter Hedge (a topiary in the shape of the Mad Hatter's hat) as a reward. Remember, this item will only be around for four days, so make sure to save up those Simoleons and purchase one as soon as you can in order to not miss out - potentially forever!
