Flowering rush

Butomus umbellatus

Flowering rush (Butomus umbellatus) is an invasive plant of riparian areas. It is a native of Africa, Asia and Eurasia and was first detected in Laprairie on the St. Lawrence River in 1905.

This plant was brought to the US intentionally as a garden species. It is difficult to control and should not be used in the garden to prevent further spread.
