Like warm, humid and sunny environment, heat, poor, not cold, has a strong climbing ability, born in the elevation of 90~610 meters flat, valley forest, hillside thicken rock cracks.

Growth temperature 15~30℃.

Sufficient light, fertile soil, good moisture, can wrap climbing companion plants, etc., are the necessary conditions for good growth. Therefore, the five-talon golden dragon especially often in the roadside, forest edges, tea gardens, parks, river banks, beaches, garbage dumps, waterways and other environments to form a single population. On the contrary, under shaded or paved growth conditions, the ecological competitiveness of the five-clawed golden dragon will be seriously affected.

Golden dragon flower with five claws
Slender five-clawed golden dragon
Golden Dragon is a self-incompatibility plant, which generally obtains seeds through cross-pollination and propagates asexually through aboveground vegetative organs.
[9]
Under the condition of abundant water and fertile soil, the five PAWS golden dragon mainly grows vegetatively, while under the condition of arid and poor soil, it mainly produces a large number of offspring by flowering and fruiting.
The plants began vegetative growth or asexual propagation after seed germination. Climbing and creeping growth are the two growth and diffusion modes of the five-clawed dragon. In the absence of support, the five-clawed golden dragon is mainly creeping growth and diffusion, in
Lie prone
During the growth process, the stolons may grow advicent roots at the internode, and advicent roots may grow lateral roots and penetrate into the soil to absorb nutrients and water for the plant. At the same time, adventitious roots were formed in some internodes and new shoots grew, which germinated into new plants under suitable water and soil conditions. It changes to climbing growth when it encounters shrubs or small trees or other objects that can be climbed.

Australia, Denmark, Scotland, Japan and other countries have listed the five-clawed golden dragon
Invasive weed
Laws were enacted to prevent further invasion of the species. The ecological environment of Fujian, Guangdong, Guangxi, Yunnan and other places in China has also been damaged by the five-clawed dragon to varying degrees.
The five-clawed golden dragon
Since its emergence in Hong Kong in 1912, the five-clawn dragon has been widely spread in southern China. It is an important weed in gardens, inhibiting the growth of local species and causing harm to biodiversity and landscape.
[12]
The harm of the five-claw Golden dragon in Guangdong: Guangdong Province is located in the South Asian tropics, with a history of frequent exchanges with the rest of the world, and is the hardest hit area of invasive weeds in China. The five-claw golden dragon has seriously damaged the natural system and artificial ecosystem in Guangdong, especially in the orchards, tea gardens and other artificial ecosystems, causing huge losses to agriculture, forestry and tourism, and even threatening human health.
Manual removal:
Manual removal is the main way of removal, but when the five-paw golden dragon enters the vegetative growth phase, the root system is developed, the growth is vigorous, and the biomass is large. Manual removal requires a lot of working hours, high labor intensity and high cost. If the timing is not right, or if the removal is not thorough, it is difficult to prevent the growth of new branches. After the stem connected to the ground is cut, if the root is not removed after being uprooted, it is easy to germinate and grow again after contact with the ground.
Chemical control:
Chemical herbicides have been reported to have a good effect on the removal of five claws
2,4-D butyl ester
The chemical herbicides, such as dioxalin, dioxadin, were injected into the stem base to remove the five claws golden dragon, and all showed high efficiency. However, the application of drugs and methods need to be selected according to the ecological environment, and try to avoid the adverse effects of chemical agents on the surrounding vegetation and non-target organisms.
Biological control:
The five-clawed golden dragon is found in the country of origin
Natural enemy
Therefore, there is no harm caused by a large amount of expansion in the country of origin; But when introduced into new habitats, it escapes predators and becomes an invasive species. The results showed that the water extracts of ligularia pseudostellata, mugwort, Aerotherma odorata, ligularia virgaurea and ligularia vulgaris had obvious inhibitory effects on seed germination and seedling growth. The larvae of the sweet potato moth of the family Lepidoptera, the brown turtle beetle of the sweet potato can eat the leaves of the five-clawed golden dragon.
