A "green coconut plant" refers to the coconut palm (Cocos nucifera) which produces young, green coconuts for drinking water and tender meat. These plants, often dwarf varieties, have slender trunks, large feather-like leaves, and can grow in tropical and subtropical climates with full sun, well-drained soil, and regular watering. Green coconuts are harvested when the fruits are immature, and the plant itself has a longer lifespan, with some varieties producing fruit within a few years.
