Golden pothos (Epipremnum aureum), often called devil’s ivy due to its resilience, is a familiar houseplant appreciated for its adaptability and trailing vines. While cultivated plants typically have small, heart-shaped leaves, its wild form is strikingly different. In its natural, untamed state, golden pothos reveals a vigorous and expansive growth habit, hinting at its impressive capabilities when unconstrained.
Characteristics of Wild Golden Pothos
In its natural environment, golden pothos transforms into a robust climbing vine with significantly larger foliage. Its vining nature allows it to climb vigorously, ascending trees and other structures, often reaching heights of 40 feet or more. Thick, fleshy stems with aerial roots firmly adhere to surfaces, providing support. These roots also absorb moisture and nutrients from the humid air, supplementing soil uptake.
Wild golden pothos exhibits a dramatic increase in leaf size. While indoor plants typically have leaves a few inches long, mature wild specimens can develop leaves up to 2-3 feet. These larger leaves often exhibit fenestrations, or natural holes, rarely seen in potted versions. Fenestrations are thought to be an adaptation, allowing light to penetrate lower leaves or helping the plant withstand strong winds.
Flowering and fruiting are rare in cultivated golden pothos, but occur in wild, mature plants. Flowers are typically a white to yellowish inflorescence, producing small berries. This “shy-flowering” nature, even in the wild, is attributed to a genetic impairment affecting a flowering hormone. Vegetative propagation through its vining habit is its primary reproductive strategy.
Natural Habitat and Global Spread
Golden pothos is native to tropical regions, originating from Mo’orea in French Polynesia, or more broadly, Southeast Asia and the Pacific Islands. It thrives in warm, humid conditions, often growing under tree canopies where it climbs towards filtered sunlight. Its natural habitat is characterized by high humidity and consistent warmth.
The global spread of golden pothos stems from its popularity as an ornamental plant. Introduced worldwide as a houseplant or for tropical landscaping, it subsequently escaped cultivation. Wild populations established in new environments, predominantly in tropical and subtropical forests and disturbed areas, where the climate mimics its native conditions.
Golden pothos has naturalized across a wide geographic range, including Southeast Asia, the Indian subcontinent, Australia, the Pacific Islands, the West Indies, and northern South Africa. Its ability to root easily from stem fragments contributes to rapid establishment and spread near cultivated areas. This naturalization highlights the plant’s adaptability outside its original range.
Ecological Impact and Management
In non-native regions, golden pothos can become an invasive species, threatening local ecosystems. Its aggressive growth habit allows it to outcompete native vegetation, forming dense ground cover and smothering trees by climbing into the canopy. This blocks sunlight from reaching host trees and understory plants, leading to their decline and altering community structure.
Golden pothos is designated as an invasive species in various parts of the world, including Florida, Hawaii, Australia, Sri Lanka, and South Africa. In Florida, it is classified as a Category II invasive species, indicating increasing abundance and potential ecological damage. Its resilience, including its ability to grow in deep shade and tolerate drought, contributes to its invasive success.
Managing wild golden pothos often involves a combination of strategies. Manual removal, though difficult due to strong aerial roots and fragmentation, can be effective for smaller infestations. Chemical control, such as foliar treatments with herbicides like triclopyr or glyphosate, is commonly used, often requiring multiple applications due to waxy leaves and robust growth. Public awareness campaigns are also important to prevent further spread, emphasizing that improper disposal of plant cuttings can lead to new wild populations.
