The Grass-leaved arrowhead (also known as Sagittaria graminea) is a cool water plant found in eastern North America. You can spot it in many places, from Canada (like Ontario and Newfoundland) all the way down to the Atlantic states in the USA. It even grows in Colorado, New Mexico, and Cuba! This plant has also started growing naturally in Washington state and in Vietnam.

This plant loves wet places, like marshes, riverbanks, and the edges of lakes. It's a type of plant that lives for many years (a perennial herb). It can grow quite tall, up to 100 centimeters (about 3 feet), and has long, thin leaves that look a lot like grass.

What are the Types of Grass-leaved Arrowhead?

Scientists have given many different names to slightly different versions of the Grass-leaved arrowhead over time. However, as of April 2014, only two main types, called subspecies, are officially recognized:

• Sagittaria graminea subsp. graminea
• Sagittaria graminea subsp. weatherbiana (Fernald) R.R.Haynes & Hellq.

These subspecies are just small variations within the same plant species.
