The acai palm tree does not grow outside of the South America area. Attempts to grow the tree outside of its native area have failed. The genus is named after the muse Euterpe of Greek mythology. The species Euterpe oleracea is usually called Açaí Palm, after the Portuguese name for the beverages made from its fruit. The vernacular name is also sometimes spelled Assai Palm in English.


Acai is a very common, tall, slender palm tree which grows 15 to 25 m in height. The average mature wild tree has 4-8 well-developed stems (10-15 cm in diameter) from a single seed and root system; however, a single seed can grow a plant providing up to 25 shoots growing individually. It has pinnate leaves that start from a prominent crownshaft that is reddish color. It has adapted to live in periodically waterlogged and flooded soils by developing special root structures called pneumatophores. It produces both female and male flowers which are quite small and are brown to purple in color.

The fruit, a small, round, black-purple drupe about 1 inch in diameter, similar in appearance and size to a grape but with less pulp, is produced in branched panicles of 700 to 900 fruits. Two crops of fruit are produced per year. The fruit has a single large seed about 7-10 mm in diameter. The epicarp of the ripe fruits is a deep purple color, or green, depending on the kind of acai and its maturity. The mesocarp is pulpy and thin, with a consistent thickness of 1 mm or less. It surrounds the voluminous and hard endocarp which contains a seed with a diminutive embryo and abundant endosperm. The seed makes up about 88-90% of the fruit.


The acai palm tree (Euterpe oleracea) is native to tropical Central and South America and grows mainly in floodplains and swamps.Açaí Palm (IPA [asai]) is a member of the genus Euterpe, which contains 7 species of palms native to tropical Central and South America, from Belize south to Brazil and Peru, growing mainly in floodplains and swamps.


It thrives best in floodplains and swamps. Grow in full sun or partial shade. Needs a consistently warm, humid environment with regular water. Grow in rich, well-drained and moist soil.


The oleracea enjoys a half sunny, half shady area where is can stay wet. As a seedling, it likes a shady moist area where it is protected from any strong elements. They are usually cultivated by seeds, which can germinate in a few weeks to a couple of months. Plant seeds in well-drained soil mixture. Water regul therapy but do not allow standing water. When the seedlings become 5-7 inches tall with one large bi-fold leaf, and a second new leaf emerging with a decent root system after which they should be planted into a 4" pot or larger upon arrival.

Flowering Season

It flowers throughout the year and the harvesting season is usually from July to December.

Folklores and Myths

Asia has been a traditional food of the native people of the Amazon for hundreds of years.Açai is known by the native people of Brazil as "içá-çai", which means "the fruit that cries". For hundreds of years, açai has been a traditional food of the native people of the Amazon Basin and a part of their folklore, finding its way into legends and myths. One of the oldest and more popular legends about açai tells the story of a village at the banks of the Pará river. Due to an unusual increase in population of the village, food became scarce and the leader of the tribe, Itaki, decreed that people could not have any more children and any newborn would be sacrificed.

A very long time ago lived a young Indian from Amazonia called Iaca. Her father was chief of a tribe that had become so large that there was not enough food left to feed the people. So the chief decided that each newborn baby would have to be killed. His own daughter gave birth to a baby just after he had taken this decision. Iaca has been crying her child's death for days alone in her hut. But one evening she had the strange feeling that she could hear her baby crying. When she went out to look for the the child, she saw a palm tree covered with fruits coming out of the soil.

Totally desesperate, she lied down under the tree and died. The day after, the tribe discovered Iaca's body under the new tree. Its fruits satisfied people's hunger and brought them back all their energy. The chief, then, abrogated his cruel order and declared that these fruits would take her daughter's name but in reverse order (Iaca becoming Acai). Thanks to the abundance of açai fruits, the tribe grew and prospered and, since now decades the acai has been highly appreciated by Brazilian people. In the fifties, doctors started to realize that the açai could be also good for health.
