It has strong growth potential, drought resistance, strong vegetative reproduction ability, and the stem segments will root when touching the soil surface; the number of flowers is large, the yield of seeds is also high, and the germination rate is extremely high. Due to these strong characteristics, it has quickly occupied many areas below mid-altitude, such as central and southern China, Hualien, Taitung, etc., and will climb to the top of the tree, occupy the crown of the tree, affect the photosynthesis of the tree, and make the forest or climbed fruit trees. Withering, it is also called "forest killer".

Originating from Ryukyu, it is also a very common wild flower in Taiwan. From the flat to the middle altitude, it is almost found in places with good sunshine. It has a lot of honey and blooms all year round. It is a good nectar source plant. It was originally introduced to Taiwan to provide a nectar source for the bees. It is strong in nature. With spread everywhere, it can be seen almost everywhere now. On roadsides, parks, fields, wastelands, weeds, etc. in sunny places. The plant height can reach 1 meter, the rhizome is erect, the base diameter can reach 0.6 cm.
