- Description: The Senegal tea plant is an emergent freshwater or marsh-growing perennial, which can form bushes up to 1.5m tall, or mats of intertwined individuals along waterways. It has large round clusters of white flowers, leading to another common name in the aquarium trade, "water snowball".
- Origin and Worldwide Distribution: It is native to Central America and South America, from Mexico to Argentina. It has becoming invasive in India, Hungary, Italy, and Australia.
- Potential or Known Impacts: It grows very quickly, up to 15cm a week, and dense mats can block waterways, and displaces native flora and fauna. It detracts from habitats' value by blocking channels and/or causing flooding. It can spread by seeds and vegetative means.
- How did it/could it get here?
It was spread due to its value as an ornamental and aquarium status.
It can be spread though seeds and vegetative means, along with being spread by becoming attached to animals and to transport.
- Is it found in Ireland or Northern Ireland? Not present in Ireland or Northern Ireland.

- Methods for Prevention: EU-level action includes a ban on sales and any planting or keeping, including in aquaria, as well as rapid eradication of any new populations to avoid the excessively high costs associated with its management later on.
