Plants can sometimes grow in polluted water, but the extent of their growth and health depends on the type and level of pollution. Some plants have the ability to tolerate or even thrive in polluted conditions, especially if the pollutants are low in concentration.

For example:

1. Phytoremediation: Certain plants, like cattails and water hyacinths, are used to clean polluted water by absorbing contaminants.
2. Hydroponics: In controlled environments, plants can grow in nutrient solutions with polluted water if the pollutants are managed.

However, high levels of pollution or toxic substances can hinder plant growth or even kill plants. The effectiveness of plants in growing in polluted water often requires careful management of the water quality and pollutant levels.
