"The flavor of a ripe prickly pear cactus fruit depends on the variety but include strawberries, watermelons, honeydew melons, figs, bananas, and citrus."www.sfc.ucdavis.edu/pubs/brochures/pricklypear.html
However, it has been produced as a flavored black china tea elsewhere:http://www.amazon.com/Hunter-Hilsberg-P ... B000OK7UDG
The sole review of this tea indicated that the flavoring is very subtle.
There are better candidates for unique tea flavors.
