Non-native plants, also referred to as exotic or alien, are plants that have been introduced to an area from their native range, either accidentally or for a purpose. The term non-native usually refers to plants from other countries or continents. However, non-native can also mean plants from another region within the same country. For example, smooth cordgrass (Spartina alterniflora), a desirable native plant on the U.S. Atlantic coast, is invasive on the Pacific coast, covering oyster beds and other vital habitat.

Approximately 1,400 of Florida’s plants are non-native in their origin. Most non-native plants do not cause problems and support human health and economic interests such as crop production and landscaping. These plants are well managed by those who grow them. Problems are often in highly disturbed areas such as roadsides or along utility corridors, and in our aquatic or natural areas.
