Lilac Tasselflower is a plant with a broad geographical presence, native to regions including Southeast Asia and parts of Africa. It has been introduced to various territories across South and Central America, the Caribbean, as well as sections of Oceania. Lilac Tasselflower may have an impact on ecosystems in certain areas where it is considered invasive, such as parts of South America and Oceania, though it doesn't universally disrupt local ecosystems. Its distribution reflects the plant's adaptability to diverse environmental conditions.

Native to southeastern Asia, lilac Tasselflower has become distributed pan-tropically including other regions of Asia. It has been cultivated for a variety of purposes, including ornamental uses. Lilac Tasselflower is listed as invasive in several countries and islands, is a weed in many field crops, and is considered a weed within its native range. It is able to tolerate a variety of conditions, allowing it to become established and grow readily in disturbed areas including fields, grasslands, roadsides, and riverbanks. The morphology of its seeds allows it to be spread long distances via wind. Furthermore, it reproduces voraciously and grows quickly, allowing it to outcompete native species once established. Mechanical control and herbicides have been effective in controlling weedy populations of lilac Tasselflower.

The best season to control lilac Tasselflower is during the spring, before the plant has reached its flowering stage. Once it has started to flower, it will quickly produce seeds, making it much harder to eradicate. Here are some organic methods to control this plant:
