Roughly ovoid, up to 15 inches (38 cm) long and 12 inches (30 cm) wide, composed of a thick, fibrous husk surrounding a somewhat spherical nut with a hard, brittle hairy shell. The nut is 6-8 inches (15-20 cm) in diameter and 10-12 inches (25-30 cm) long. Three sunken holes of softer tissue - called "eyes" - are at one end of the nut.

Inside the shell is a thin, white, fleshy layer, about one inch thick at maturity. This layer is known as the "meat" or copra. The interior of the nut is hollow, but partially filled with a watery liquid called "coconut milk". The meat is soft and jelly-like when immature, but it becomes firm at maturity. Coconut milk is abundant in unripe fruits, but the coconut milk is gradually absorbed as ripening proceeds. The fruits are green at first, turning brownish as they mature. Yellow-fruit varieties change from yellow to brown as they mature.

Coconut Palm propagation is entirely from seed – the coconuts, which are ready for planting if they produce an audible "sloshing" sound when shaken. The nuts are placed on their sides and buried with sand or mulch to about one-half the thickness of the nut. They may be planted in closely spaced rows in well drained seedbeds, or the nuts may be planted directly into large pots. Germination is best under high temperatures (90-100 °F). Upon germination, the shoot and root emerge through the side or one end of the nut. Young palms, about 6 months old, can be transplanted directly into the field or can be grown in pots in the nursery for a few more years.

The coconut palm starts fruiting 6-10 years after the seed germinates and reaches full production at 15-20 years of age. The tree continues to fruit until it is about 80 years old, with an annual production of 50-200 fruits per tree, depending on cultivar and climate. The fruits require about a year to develop and are generally produced regularly throughout the year.
