Lagenaria siceraria is a highly versatile gourd cultivated worldwide for its edible young fruits and hard-shelled mature gourds used in crafts and culture. The plant is a fast-growing, trailing vine with large night-blooming white flowers, variable-shaped fruits, and hard-shelled gourds when mature.
The bottle gourd or calabash (Lagenaria siceraria, family Cucurbitaceae) is a vigorous annual climber with stems about 9 metres long that scramble over the ground and into other plants, holding on with tendrils. It is one of the earliest domesticated plants, with evidence of cultivation possibly as early as 13,000 BC in Peru, and its original home, probably in Africa or Asia, is uncertain; it is not known in the wild. It is grown throughout the tropics and subtropics for its edible fruit and above all for the hard, woody shell of the ripe fruit, which is made into containers, bowls and musical instruments.
It is a plant of the moist lowland tropics and grows best below 500 metres, where daytime temperatures are 19 to 27°C and rainfall is 1,200 to 1,800 mm a year. It needs a warm, sunny, sheltered position and well-drained, moist, fertile soil, with plenty of water in the growing season, and it is killed by frost. The pulp around the seeds is toxic. The seed is sown where the plant is to grow and germinates in four to five days.

Traditionally used as a tonic, diuretic, and remedy for metabolic, digestive, and cardiovascular conditions, though bitter varieties can be toxic.
Non-bitter fruits, shoots, leaves, and seeds are widely consumed as vegetables and snacks across Africa, Asia, Europe, and the Americas.
Dried gourds are globally important for making containers, musical instruments, and cultural symbols associated with health, music, and tradition.
The plant thrives in warm climates on fertile soils, is grown from seed on trellises or mounds, and is harvested young for food or mature for craft use.
