Koanophyllon is a genus of plants in the family Asteraceae.[1][2][3] They are perennials and shrubs (rarely vines or trees) and are native to South America, Central America, the West Indies, Mexico, with a few species range extending into the United States. The flowers are white to pinkish (rarely purple).[3]
Cuba alone has 21 endemic species, seven of which only grow in serpentine soils, and some of which accumulate minerals such as nickel and manganese.[4]
