In what could be a bit of a confusing update, Zynga has released an entire set of limited edition items in the original FarmVille store in a new English Countryside theme. To be clear, these items are part of an entirely separate theme, not relating only to the actual English Countryside expansion, which started rolling out to users today. These items are available to place on your original farm, and function as you would expect.
That clarification out of the way, there are four new trees available to purchase in the store, with one being a re-release, and another already being available as a Mystery Seedling for a few days now. The trees are the Dogwood Tree, Pink Dogwood Tree, Chestnut Tree and Hazelnut Tree.
For those that were playing the game back during the Winter Wonderland event, you'll recognize the Chestnut & Hazelnut Trees as ones that was available to purchase from the market for 6 and 14 Farm Cash, respectively, and those prices are retained in this re-release. Remember, if you don't have a Hazelnut Tree, you can just purchase the Chestnut Tree and then hope to get a Hazelnut Tree as a Mystery Seedling from it when placed in an Orchard.
