Yellow flag iris

Iris pseudacorus

Description:

An invasive aquatic plant which can create dense, monotypic stands, outcompeting other plants in the ecosystem. Where it is invasive, it is tough to remove on a large scale.

Habitat:

Spotted at the edge of a pond at Helen McCabe State Park.

Notes:

The rhizome has historically been used as an herbal remedy, most often as an emetic.[citation needed] When applied to the skin or inhaled, the tannin-rich juices can be acrid and irritating. This plant has been used as a form of water treatment since it has the ability to take up heavy metals through its roots and is featured in many AS Level Biology practicals as its ability to grow in low pH levels makes it a useful indicator. Is pollinated by bumble-bees and long-tongued flies.
