Actually, they said once that each fruit is uniqe, but there are so many DF users in the same time, so there must be some replenshing source of the fruits...Originally Posted by Mae
then again, those fruits are 'tresures', they don't neccessrely rot like normal fruits, maybe there was once "a tree of life" that spourted devil fruits, but is no more existence...
though, I can think of some evidence against it, the spring fruit and the sword fruit don't feet in ,,,
