Recently FarmVille has just recently release these crops, animals and trees with constellations names. They are rare and exclusive and you can buy it from the Market for coins but the twist is it’s like a mastery unlock game. You have to master the first animal to unlock the next one. Like in order to purchase/unlock the “Aquarius Duck” you have to master first the “Mercury Rabbit” and so on. It will have 10 stages and will start from “Mercury” and will go up to “Celestial”.
Wondering which FarmVille Tree can be harvested for Jade? Here is a list of Trees that can be harvested for Jade currency:
Note: Some of these have level requirements in order to unlock, or currently unreleased, or Limited Edition Items.
Asian White Birch Tree (level req: 50, yield: 35 jade)
