The Blue Java banana, often called the Ice Cream banana, is famous for its remarkable flavor and texture. Ripe fruit has a creamy consistency and a taste that is widely compared to vanilla ice cream or custard. The plant gets its name from the silvery-blue color of the unripe fruit, which turns pale yellow when ripe.
This is a larger banana plant, reaching 12 to 20 feet tall, with a distinctive silvery cast to its leaves from a waxy coating that also provides some wind resistance. Blue Java is notably more cold-tolerant than most fruiting bananas, making it a popular choice for growers in zones 8 and 9.
Growing Conditions
Blue Java does best in full sun with protection from sustained strong winds, though it handles wind better than many varieties thanks to its thicker petioles and waxy leaf coating. It needs rich, well-draining soil and heavy feeding during the growing season (see Fertilizing Guide).
Its cold tolerance is a major advantage. Established plants can handle brief temperatures down to about 20°F, though the pseudostem will die back. The rhizome usually survives and regrows in spring if protected with heavy mulch (see Overwintering). In zone 9, it reliably fruits outdoors.
Time to Fruit
Blue Java is on the slower side for fruiting, typically 15 to 24 months from a pup to first harvest. The fruit is smaller than Cavendish types — usually 4 to 6 inches — but the flavor more than compensates. See How Long Do Banana Plants Take to Fruit? and When to Harvest.

Propagation
Propagate by pup division. Blue Java produces pups reliably but not as prolifically as Cavendish types.
Common Issues
Susceptible to Panama disease (Fusarium wilt) Race 1. Also watch for banana weevils in areas where they are present. Wind damage is less of a concern than with other tall varieties, but still possible in storms.
