American Dragonhead (Dracocephalum parviflorum) is a hardy annual or biennial plant native to the northern and western regions of North America, including Alaska, Alberta, Arizona, British Columbia, Colorado, Connecticut, Delaware, Idaho, and parts of Canada such as Labrador, Manitoba, Ontario, Québec, and Saskatchewan. Known for its edible seeds, this plant thrives in moist conditions with a preference for light or partial sun. It can grow up to 1 meter tall and is adaptable to various soil types, including sandy, medium, and clay-heavy soils. Its native range extends from the northern United States through Canada into parts of the western U.S., making it a valuable addition to gardens and landscapes in similar climates. One distinctive feature of American Dragonhead is its light requirement; while it can tolerate partial shade, full sun tends to enhance its growth and vigor.
