Selenicereus megalanthus, synonym Hylocereus megalanthus,[1] is a cactus species in the genus Selenicereus that is native to northern South America, where it is known, along with its fruit, by the name of pitahaya. The species is grown commercially for its yellow fruit, but is also an impressive ornamental climbing vine with perhaps the largest flowers of all cacti.

The yellow skinned fruit of S. megalanthus has thorns, unlike the green, red or yellow skinned dragon fruits of S. undatus, S. monacanthus and their cultivated hybrids. S. megalanthus is commonly known as "yellow dragon fruit", "yellow pitahaya", "kirin fruit", or "yellow pitaya". This name leads at times to confusion, as unrelated cultivars of other dragonfruit species can also have yellow skinned fruit. One example of a yellow dragonfruit cultivar not related to S. megalanthus is 'Australian Gold'.

Etymology

Megalanthus (Greek) – large flowered. This species produces some of the largest flowers within the cactus family.

Origin and habitat

The species is native to

riparian forests and is epiphytic or xerophytic
.

Description

Cultivation

This is an easily cultivated, fast-growing plant. It needs a compost containing plenty of humus, and sufficient moisture in summer. It should not be kept in temperatures under 8 °C (46.5 °F) in winter. It can be grown in semi-shade, but it does best in full sunlight. Extra light in the early spring stimulates budding. The plant flowers in June to October. The plant can grow to a very large size.
