Hi Stela,
Yours is peeling, and that is a good sign that flowers will be coming soon. I bought my pitomba with fruit on it, so not sure how long you will have to wait. Have also been told that the fruit improves as the tree matures, so don't get discouraged if the 1st fruits are not too tasty ... mine are delicious!
Happy Gardening!
