This is a Guava hybrid with Araca Pera, a rare flavorful wild guava from the Brazilian Amazon which is rare in cultivation.
These fruit are 1.5-2", with an acidic, sour guava-like flavor. Its juice is concentrated and must be diluted and sweetened to produce a delicious drink. The fruit is processed into ice cream sorbet, gelatins and candies. It is the major source of a special Guava Wine production. A great container specimen.
