It is also called devil's vine or devil's ivy because it is almost impossible to kill and it stays green even when kept in the dark. It is sometimes mistakenly labeled as a '' Philodendron, Pothos or Scindapsus'' in plant stores. It is commonly known as a money plant in many parts of the Indian subcontinent.

History and etymology

This species has been assigned to a number of genera. In 1880 when it was first described, it was named ''Pothos aureus'', which is in part why it is often commonly referred to as a "pothos". After a flower was observed in 1962, it was given the new name of ''Rhaphidophora aurea''. However, after closer examination of the flower, researchers noticed its heightened similarity to ''
Epipremnum pinnatum ''Epipremnum pinnatum'' is a species of flowering plant in the family Araceae. It has many common names, including centipede tongavine and dragon-tail plant. In the Philippines, it is known in Tagalog as ''tibatib''. Distribution The plant ha ...
'' and synonymised it with that species. Only after closer observation to the entirety of the plant, including the leaves and growing patterns, did researchers again separate it from ''E. pinnatum'', and classify it as ''E. aureum''.


Description

''Epipremnum aureum'' is an evergreen vine growing to tall, with stems up to in diameter, climbing using aerial roots which adhere to surfaces. The

are alternate, heart-shaped, entire on juvenile plants, but irregularly pinnatifid on mature plants, up to long and broad; juvenile leaves are much smaller, typically under long. The flowers are produced in a spathe up to long. This plant produces trailing stems when it climbs up trees and these take root when they reach the ground and grow along with it. The leaves on these trailing stems grow up to long and are the ones normally seen on this plant when it is cultivated as a potted plant.


Shy-flowering nature

While ''E. aureum'' is classified as an

, which typically produce flowers at some point in their life cycle, it is the only reported species in its family ( Araceae) that does not develop a flower. Regardless of where this “shy-flowering” plant is grown or what the conditions are like, it will not flower due to a genetic impairment of the gibberellin (GA) biosynthetic gene, EaGA3ox1. This impairment causes the plant to be unable to develop bioactive GAs, which is what is responsible for the flowering of plants via the floral meristem identity gene EaLFY. In ''E. aureum'', the floral meristem identity gene expression is absent due to the lack of GAs from EaGA3ox1. It was found that when GAs were experimentally sprayed onto the plant, flowering was induced.

. It is often used in decorative displays in shopping centers, offices, and other public locations largely because it requires little care and is also attractively leafy. In tropical countries, it is found in many parks and gardens and tends to grow naturally. As an indoor plant it can reach more than in height if given the adequate support (a totem or moss pole to climb), but hardly develops adult-sized leaves. The best results are achieved by providing indirect light; it tolerates an intense luminosity, but long periods of direct sunlight burn the leaves. It lives well with a temperature between . Generally, the plant will only need watering when the soil feels dry to the touch (typically once every one to two weeks). A liquid fertilizer can be added in the spring and it must be replanted every two years. However, it is a very robust plant that supports bad growing conditions. The plant grows rapidly in hydroponic culture. It can be cultivated from a cutting, a part of a plant used in plant propagation. Cuttings, however, can carry various diseases such as

. The plant can remove indoor pollutants such as formaldehyde, trichloroethene, toluene, xylene, and benzene in controlled circumstances (e.g. a sealed room). A study found that this effect declined as the molecular weight of the polluting substance increased. The plant is sometimes used in aquariums, placed on top of the aquarium, and allowed to grow roots in the water. This is beneficial to the plant and the aquarium as it absorbs many nitrates and uses them for growth.


Cultivars

There are several cultivars known in the houseplant community. Common names for them used in the houseplant community include Golden Pothos, Neon Pothos, N'joy, Pearls n' Jade, Marble Queen, Jade, Manjula, Global Green, and Snow Queen.


Toxicity

The plant is listed as toxic to cats and dogs by the ASPCA, because of the presence of insoluble raphides. Care should be taken to ensure the plant is not consumed by pets. Symptoms may include oral irritation, vomiting, and difficulty in swallowing. Due to the

, and other places where it has been planted as a decorative plant, or to hold steep banks along roads. It was included in the Florida Exotic Pest Control Council's 1999 list of invasive species. A study published in the South African Journal of Botany found the species to be a potential risk of becoming an invasive species along the coasts of South Africa. It suggested a number of different ways to prevent the spreading of the species in the wild, one of which included barring the cultivation of the species outside of an unsupervised area. Additionally, however, the study pointed out that ''E. aureum'' cannot propagate on a large scale due to its lack of seed banks as well as its minimal immunity to herbicides. If the plant is maintained in a controlled area, it is not as significant of a threat as when it grows freely in the wild.
