紫茎泽兰, also known as Mikania micrantha, is a fast-growing, perennial vine native to tropical regions of the Americas. It is characterized by its purple stems and heart-shaped leaves. This plant can quickly cover large areas, making it a common sight in disturbed habitats. While it may appear attractive, 紫茎泽兰 is considered an invasive species in many parts of the world, including Southeast Asia and Australia. Its rapid growth can outcompete native vegetation, leading to biodiversity loss and ecological imbalance. Efforts are ongoing to manage its spread and mitigate its impact on local ecosystems.
