Flowering Rush

 

Latin name:

Butomus umbellatus  

Native to:

Northern Africa, Asia and Europe 

Regional Distribution:

Flowering rush has not yet been found in the Columbia Shuswap region but is an invasive species to watch for as it is currently found in isolated locations around the province of BC. It has had a major ecological impact on the natural ecosystems of the Great Lakes and is causing concern in BC.

Description:

Flowering rush is an aquatic perennial commonly found along shorelines of lakes and rivers, in canals and ditches. This almond-scented plant produces an umbrella shaped array of small pink flowers. The stem can grow up the 3 feet in height and forms dense stands along the shoreline.  Before the flowering stage of this plant it can easily be mistaken for Seacoast bulrush and bur-reed.

Control:

Mechanical control such as careful digging is an effective method in areas where flowering rush is present in low density. The entire plant must be removed in order to ensure complete eradication of the species. Buds or other root fragments can quickly and easily develop on soil.

For lakes without Flowering Rush, prevention is the best control. Clean, Drain and Dry your boat before launching into another water-body.
