It can be grown in a pet's front or back garden by purchasing the Limited Edition, Heavenly Tree Seed at the Outdoor Store. This tree seed was only available for purchase from May 11 - 12, 2011. After planting, it will take 72 hours for the tree to reach maturity. Afterward, the tree will begin producing fruit, one fruit at a time, randomly. A pet can have up to three total fruits on the tree at once, unless you have the Fruit Fairy, in which case you can have four fruits.
