'Mammoth' has the largest (up to half a pound or more) and tastiest fruit of all the Pineapple guava cultivars, a rare combination in the fruit world. The pulp contains a strong guava flavor with strawberry undertones. Matures earlier than the species, with fruit often ripening by September. Grown in 1 gal containers, this new crop of trees as of September 2016 is much smaller than photo, about 8" tall, no branching, very narrow caliper, no older wood. TEMPORARILY OUT OF STOCK.
