Everybody probably has grown some but I have never, ever seen one in my town. (I got my game on Christmas.) Is this the same with some people or am I just seriously unlucky and my game hates me?
That happened to me as well, I accidentally sold my first perfect fruit.
Fortunately I had the same native fruit as a friend of mine, so he gave me a punnet of them. This was after going through a month or two without any perfect fruit at all, which was frustrating and not recommended.
Since it will take a very long time for fertilizer to appear in your store, I suggest buying a basket of your native Perfect Fruit from somebody here.
If it's Oranges or Pears I could help you with a full punnet.
