Abiu (Pouteria caimito)—The abiu is a small evergreen fruit tree native to South America. The round bright yellow skinned fruits, which are borne directly on the tree branches several times a year, are considered one of the best fruits of the Amazon Basin. The white, translucent flesh is sweet with a slight flavor of caramel with honeydew melon and the texture of a well ripened persimmon. The Gray and Z-2 abius are selections from Australia with good quality fruits that weigh about a pound. The trees need some wind protection with good draining soil.
Burmese Grape (Baccaurea sapida)—Called Mafai in Thailand, this attractive tree has 1 inch yellow fruits that hang in long clusters from the main branches under the tree. The ripened fruits are sweet with a subacid flavor. The female Lien Tong and Tau Long cultivars need a male to pollinate for fruit set.
Canistel (Pouteria campechiana)—The canistel is a very prolific bearing fruit tree from Central America. The orange yellow fruit has a rich, sweet flavored pulp tasting somewhat like a sweet potato or chestnut. The highly nutritious fruits are eaten fresh or used in ice creams and breads. Saludo is a variety with large round fruits with moist flesh. The trees seem to have a good wind tolerance and are very adaptable to various soils and climates in Hawaii
Carambola (Averrhoa carambola)—The carambola is a productive bearing fruit tree from Malaysia, where the fruits are eaten fresh or processed into juice. Grafted trees of good varieties usually start bearing in two years. The ornamental trees bear clusters of small lilac colored flowers which are followed by exotic, waxy looking, star shaped fruits. Superior quality clones have been developed and are available to home growers. Kary is a carambola developed at the U.H. Poamoho Experiment Station as a selected seedling of the Kembangan carambola. Fruits are orange yellow when ripe, sweet, and pleasantly flavored with a crisp texture. Fwang Tung is a variety that originated as a seedling from a Thai variety in Florida. The greenish yellow fruits are large and sweet with a crisp and refreshing taste. The Leng Bak is also a sweet, crisp fruit that is also great for making juice.
Citrus—Citrus trees have been proven to be very popular with home gardeners. Under Hawaii’s tropical climate, they have shown their ability to produce two or more crops per year. Home growers should select a plant grafted onto a rootstock suitable to their soil type and resistant to diseases in their locality. The choice of rootstocks also plays a role in determining the fruit quality and size, drought tolerance, and tree size. The following are descriptions of some citrus varieties available to home gardeners:
Cara Cara Orange is a red fleshed navel orange which originated as a sport mutation in Venezuela. Fruits borne on trees grown in various areas in Hawaii have shown a dark red pulp color. Fruits are similar in quality to the Washington Navel Orange.
Halawa Pummelo is a giant size (up to 16 pounds) red fleshed pummelo. It is very juicy, sweet, and pleasantly flavored with no bitter after taste.
Guava (Psidium guajava)—The guava is a tropical American tree that is grown locally for its acidic pulp, which is processed into fruit juices, purees, jellies, jams, and syrups. Acid varieties with an abundance of pink pulp, such as Waiakea, are valued for processing. Holmberg, Hong Kong Pink, Indonesian Seedless, and Crystal Seedless are sweet dessert types with low acid content that are valued for eating as a fresh fruit. Guavas are very hardy plants that are adaptable to various soils and climates in Hawaii. Plants seem to fruit well even with much neglect
Mountain or Malay Apple (Syzygium malaccense)—The mountain apple is a very refreshing fruit with an aromatic, pleasant taste. Known as Ohia apples by the Hawaiians, the handsome trees originally came from Malaysia and traveled throughout the Pacific in early Polynesian times. Cultivars propagated vegetatively include Kingston, a very large, dark red, juicy fruit weighing up to one pound and Rookman, a long medium sized fruit with a sweetish flavor. This is one of the few fruit trees that can grow in sun or semi shaded areas with some wind protection.
Soursop (Annona muricata)—The soursop is a fruit tree from the American tropics that is popularly grown for its juicy, aromatic fruits. The large 3 to 5 pound fruits are grown for its acid-sweet juice, which are processed into drinks and sherbets. Varieties include Whitman Fiberless, a more productive cultivar with delicious melting pulp, and Dulce, a sweet variety with low acid content.
Sugar Apple (Annona squamosa)—The sugar apple is a small semi-deciduous tree from tropical America. The fruits, which are green, purple, or yellow skinned, look somewhat like a globe artichoke with many carpels which may separate when ripe. The white, soft flesh surrounding many seeds within the aromatic fruit has a sweet pleasant flavor. A seedless, green skinned variety from the Philippines is being propagated by grafting.
