The sakura dragon was a limited edition dragon for spring of 2012, for players level 7 and over.
The most effective method of breeding a sakura dragon were a flower dragon (lv 10 left) and a tree dragon (lv 10 right). This has about a 20% success rate.
Other methods included:
The egg was brown with pink sakura (cherry) blossoms. It took 10 hours to breed, and 10 more hours to hatch.
It was also available for purchase in the market for 300 gems.
There are several ways of breeding a tree dragon. The most effective is an Air Dragon (lv 10 left) and a Moss Dragon (lv 10 right). This has about a 25% success rate. An alternative method is Flower and Moss.
