The E. itaguahensis also fruits a lot faster and a lot smaller , started to fruit this year at 50 cm tall , just a few fruits though and the birds got them....so I cannot comment about the taste.
Now waiting for the copacabana , not holding my breath according to Harri and Marco's comments , but then again , Marco told me the neonitida was his favorite Eugenia and for me it is way down the list.
