Jambu trees produce fruit of the same name that are small, sweet and crisp, says Blue Planet Biomes. Jambu grow naturally between southern India and Malaya, but the tree is undergoing adaptation to cooler regions. Jambu are often called "watery rose apples," and a dove bears the same name as the true, the Jambu fruit dove.
Adapting to Cooler Climates
Jambu fruit grows best in tropical-like climates; they dry out quickly, so they are best cultivated in an atmosphere with warmth and moisture. However, CRFG.org claims that the jambu fruit, or the "watery rose apple" is adapting to cooler weather and withstanding temperatures as low as 25 degrees Fahrenheit. The fruit is now grown in Florida and California.
Adapting to Warm Locations
The Jambu fruit may even adapt to a warm climate, depending on the location's resources. In Indonesia, the tree blooms white and red fruits bi-annually, so they are available in August and November, says Blue Planet Biome. White Jambu is more tart than red Jambu, which is very small and sweet. However, in places like Malaya, Jambu produces fruit in a variety of colors, pale green, light pink and both deep red and brownish-red.
Jambu Fruit Dove Adaptation
The Jambu fruit dove is rare, and the bird is known for its distinctive features and bright pink and green colors. Their features also include a white eye ring, a bright orange bill and red feet. The doves live roughly 1,500 meters (almost a mile) high in the trees, claims Its Nature; however, they are becoming extinct due to the destruction of the rain forest in countries like Indonesia, Malaysia and Thailand. The doves have not yet adapted to less tropical areas, making them a threatened species.
