Heart of palm is a vegetable harvested from the inner core and growing bud of certain palm trees, most notably the coconut (Cocos nucifera), juçara (Euterpe edulis), açaí palm (Euterpe oleracea), palmetto (Sabal spp.), and peach palm. Harvesting of many uncultivated or wild single-stemmed palms results in palm tree death (e.g. Geonoma edulis). However, other palm species are clonal or multi-stemmed plants (e.g. Prestoea acuminata, Euterpe oleracea), and moderate harvesting will not kill the entire clonal palm. Heart of palm may be eaten on its own, and often it is eaten in a salad. There are palm varieties that have become domesticated farm species as an alternative to sourcing from wild palms. The main variety that has been domesticated is Bactris gasipaes, known in English as peach palm. This variety is the most widely used for canning. Peach palms are self-suckering and produce multiple stems, with up to 40 on one plant. This lets producers lower costs by harvesting several stems from a plant while avoiding the death of the palm. Another advantage is that the peach palm has been selectively bred to eliminate the thorns of its wild cousins. Since harvesting is still labor-intensive, palm hearts are regarded as a delicacy. Names Major local names for heart of palm include palm cabbage or palmetto in Florida and Trinidad; palmito in South and Central America; ubod in the Philippines; củ hủ dừa in Vietnam; cœur de palmier in French; corazón de palma or col de palma in Spanish; coração de palma or palmito in Portuguese; and cuore di palma in Italian. Nutrition Hearts of palm are rich in fiber, potassium, iron, zinc, phosphorus, copper, vitamins B2, B6, and C. They are ranked as a "good" source of protein, riboflavin, and potassium, and as a "very good source" of dietary fiber, vitamin C, folate, calcium, iron, magnesium, phosphorus, zinc, copper, and especially, manganese, along with being a good ratio between omega-3 and omega-6 fatty acids. The high sodium content noted on the chart for hearts of palm relates to the canned product; it is not present in the fresh product. Cultivation Harvesting and eating heart of palm is traditional in the cultures of Southeast Asia and South and Central America, pre-dating the colonial era. The species used depend on the region. In Southeast Asia, the dominant source of hearts of palm are coconuts (Cocos nucifera). Other palms species used include rattans
