Penstemon debilis, the Parachute penstemon or Parachute beardtongue, is one of the rarest plants in North America, found only 5 places in the world, all of them located on the Roan Plateau in Garfield County, of Western Colorado.

The Denver Botanic Gardens has the Parachute penstemon on display with other native plants of the Roan Plateau.

The area is very arid and has sparse vegetation, containing sages, grasses and bushes.

The Parachute penstemon has been identified to qualify for protection under the Endangered Species Act by the United States Fish and Wildlife Service, but failed to be protected, due to large amounts of natural gas in the area.

On July 27, 2011, the plant was federally listed as a threatened species of the United States, a ruling which took effect on August 26, 2011.
