Decaisnea fruit plant, commonly known as the dead man's fingers, is native to which continent?

Decaisnea, known commonly as dead man's fingers, blue bean plant or blue sausage fruit, is a genus of flowering plant native to eastern Asia, from China west to Nepal, northeast India (Sikkim), Bhutan and south of Myanmar. The greenish-yellow flowers of Decaisnea are produced in drooping racemes 25 to 50 cm (9.84 to 19.68 inches) long. About 7-12 cm (2.75 to 4.72 inches) long, soft to the touch and covered in eerily skin-like peel, the fruit of Decaisnea does really feel like a cold human finger, hence it's common name 'dead man's finger'.

Decaisnea is grown as an ornamental plant for its foliage and decorative fruit, bright blue in many cultivated specimens. Most plants in cultivation derive from Chinese seed and are commonly grown under the name D. fargesii. The plants are successfully grown in cooler temperate climates, and in fertile, well-drained soil. They are tolerant of temperatures as low as -15 °C (5 °F).

The fruit is valued for eating by the Lepcha people of Sikkim. The pulpy flesh is transparent and tastes deliciously sweet and subtle, with notes of cucumber and melon, so it can be utilised in sweet or savoury recipes. The pulp is edible however the seeds are not.
