Question: Are Camassia and Chelone both native to North America?
Context: Camassia quamash, commonly known as camas, small camas, common camas, common camash or quamash, is a perennial herb.  It is one species of the genus "Camassia" and is native to western North America in large areas of southern Canada and the northwestern United States, from British Columbia and Alberta to California and east from Washington state to Montana and Wyoming. Agrilus planipennis, commonly known as the emerald ash borer, is a green buprestid or jewel beetle native to northeastern Asia that feeds on ash species.  Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.  In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area.  Outside its native range, it is an invasive species and is highly destructive to ash trees native to northwest Europe and North America.  Prior to being found in North America, very little was known about emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America.  Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, insecticides, and biological control. Chelone is a genus of four species of perennial herbaceous plants native to eastern North America.  They all have similarly shaped flowers (which led to the name turtlehead due to their resemblance to the head of a turtle), which vary in color from white to red, purple or pink.  "C. cuthbertii", "C. glabra", and "C. lyonii" are diploid and "C. obliqua" is either tetraploid or hexaploid. This is a list of the native wild mammal species recorded in Central America.  Central America is usually defined as the southernmost extension of North America; however, from a biological standpoint it is useful to view it as a separate region of the Americas.  Central America is distinct from the remainder of North America in being a tropical region, part of the Neotropic ecozone, whose flora and fauna display a strong South American influence.  The rest of North America is mostly subtropical or temperate, belongs to the Nearctic ecozone, and has many fewer species of South American origin. Cakile is a genus within the flowering plant family Brassicaceae.  Species in this genus are commonly known as searockets, though this name on its own is applied particularly to whatever member of the species is native or most common in the region concerned, the European searocket "Cakile maritima" in Europe, and the American searocket "C. edentula" in North America.  The genus is native to Europe, Asia and North America, but the European searocket has been introduced into North America and has spread widely on both east and west coasts; in many places it is replacing the native "C. edentula", and is regarded as an undesirable invasive species. Chelone glabra (white turtlehead) is an herbaceous species of plant native to North America.  Its native range extends from Georgia to Newfoundland and Labrador and from Mississippi to Manitoba.  Its natural habitat is wet areas, such as riparian forests and swamps. The Native Tour (also known as the Native Summer Tour in North America or Native Fall Tour in Europe) is the third headlining concert tour by American pop-rock band, OneRepublic in support of their third studio album, "Native" (2013).  OneRepublic were joined on the Native Summer leg of the tour by, The Script and American Authors, and on the European "Native Fall Tour" leg by Kongos.  The tour has traveled across five continents; Asia, Europe, Oceania, North America, and Africa.  The tour began on April 2, 2013, in Milan, Italy and finished on September 20, 2015, in São Paulo, Brazil. Camassia is a genus of plants in the asparagus family native to Canada and the United States.  Common names include camas, quamash, Indian hyacinth, camash, and wild hyacinth. Camassia cusickii, common name Cussick's camas, is a species of plant in the Asparagaceae family (subfamily Agavoideae).  It is native to parts of North America.  It has linear leaves with parallel venation and flowers in parts of three.  The flowers are usually ice blue or baby blue in color, although they can be various shades of blue, cream and white. Camassia scilloides is a perennial herb known commonly as Atlantic camas, wild hyacinth, and eastern camas.  It is native to the eastern half of North America, including Ontario and the eastern United States.
