Habitat and Distribution
A. aculeata is an extremely widespread palm from tropical America. Its range begins in eastern Brazil, and extends north through Venezuela, Colombia, and Central America. Cuba and the other Carribean Islands also provide habitat for this variable species. It has been speculated that such a broad range was assisted by the migrations and cultures of the prehistoric peoples of this region.

These impressive palms bear a superficial resemblance to the majestic Royal palm from a distance, due to its size and attractive form. However on closer inspection, the copious spines on most forms, along with the plumose character of the leaves, give its true identity away even to the relatively uninformed. Editing by edric.
This palm can be very fast growing and surprisingly cold hardy. However, because this species is so variable, its growth characteristics can be variable as well. It is most common in open sunny areas, and is fairly drought tolerant. However, it makes a much more attractive specimen with adequate water. It is tolerant of many soils and conditions, but will not handle shady locations. One must be careful when planting such a vicious palm. As a juvenile, with its sharp and plentiful spines, it can present a hazard to children and pets, not to mention, the well caring gardener.
In climates like Florida (including the central part) these are very fast-growing palms. According to informants in Orlando, Acrocomia can reach 30 feet (10 m) tall in about 5 - 10 years. They are much slower-growing in Mediterranean climates like Southern California, but will thrive with plenty of water. In any climate, avoid placing where they might get bumped into by sensitive people.
Comments and Curiosities
At one time, due to the previously mentioned variabilty, there were 2 dozen described species. Today, according to who you recognize, there are as few as two. The uses of all parts of this palm would take several paragraphs to list, and would provide interesting reading.
In Costa Rica, the fruits are eaten by the cattle in the plains. Also, Costa Rican people use the "Coyol Palm" for making "Coyol Wine", specially in the Guanacaste province. This wine is made from the latex that oozes from the trunk, after chopping the palm down. When cooked, in Panamá, the fruits are peeled and smashed to form a paste, which is then mixed with brown sugar and water and let to ferment. The final product is known as "chicha", a type of liqueur.
Present in all semi-dry to tropical America, Acrocomia aculeata has not failed to colonize the West Indies. Victim of its sharp thorns which it is fully covered at a very young age, he was almost completely eradicated because of the danger it presents for both men and livestock. Happily, sometimes it still surprises along the gullies are difficult to access, a feathery palm of "Grougrou" dangling at the mercy of winds. It is time to replant the palm gorgeous, extremely rapid growth and capable of withstanding a "Lent" severe without watering.
Grande-Terre in Guadeloupe is the home of Acrocomia (karukerana) some features distinguish them from other forms of the species. However, we will stick to botanical nomenclature in that Acrocomia karukerana is not considered a separate species, but as a simple variation of the population within Acrocomia aculeata. On populations designated under the name Acrocomia karukerana, these seem to have different characteristics from others (spines arranged without order on the stem, when they are arranged in regular rings on the stems of Acrocomia aculeata.) However, this character does not seem enough to make it a separate species, especially since we found these features on some of the Guyanese Acrocomia aculeata population. In any case, this palm is a very special variant of the species Type Acrocomia aculeata, which seems to be almost exclusively on Guadeloupe. It would almost be an endemic form. (see photos of var. below).
Despite its endemism, this palm has been massively removed from areas where it once grew in abundance, these flat lands of the Great Earth have been largely cleared for the benefit of agriculture, livestock, housing and other human activity. This palm is protected by law. Nevertheless, it is unfortunately now on the verge of extinction as their numbers are reduced. The name of this palm (karukerana) means "Karukera" old Indian name of Guadeloupe.
Uses: The main use is in landscaping, tolerates transplantation as a juvenile and adult. Its fruits are sold along the railway line to Puerto Suarez Roboré, Santiago de Chiquitos, Santa Cruz. Its other uses include, Medicinal and Veterinary: Respiratory system, Sensory system, the root is used for the digestive system, and both the root and stem to make beverages. Ornamental, Cosmetics, Animal Food, and also the palm heart is eaten.
This is a tillering palm, it exhibits saxophone style root growth (it has a heel), keep top third of heel above soil elevation!
