Vegetable harvested from the inner core and growing bud of certain palm trees (notably the coconut (Cocos nucifera), Palmito Juçara (Euterpe edulis), Açaí palm (Euterpe oleracea), sabal (Sabal spp.) and pejibaye (Bactris gasipaes) palms). It is costly because harvesting in the wild kills the tree. Heart of palm is often eaten in a salad, sometimes called "millionaire's salad," and also in vegetarian spreads.
