What Is Phragmites?

Phragmites (Phragmites australis) or Common Reed is a non-native perennial grass that was introduced to North America from Eurasia. It is a concern for wetlands and wet areas because it:

– can grow into very dense monoculture stands

– spreads quickly (seeds, above ground stolons, and underground rhizomes)

– can reach heights of up to 5 metres (16 feet)

– outcompetes native species for water and nutrients

– displaces native vegetation and biodiversity

– provides poor habitat for wildlife

PREVENT THE SPREAD

You can help to prevent the spread of Phragmites.

– stay on designated trails to prevent the spread of seeds

– do not break the seed heads off to bring home

– do not plant it in your garden

– do not buy it from a garden centre

– follow the best practices for management and control click here

– do not compost it.
