Plant names that start with the letter "X" include Xyris ambigua and species in the genus Xanthosoma. Xyris ambigua, which is also called morning yellow-eyed grass, is indigenous to Florida. Xanthosoma plants are indigenous to Central and South America.
Xyris ambigua usually grows in wetland environments, such as bogs and lake margins. It is a tall plant with sizable, cone-shaped flowers that bloom from spring to autumn.
Xanthosoma plants grow well in areas with partial shade but with the proper moisture level, Xanthosoma varieties can also tolerate conditions with more light. They have attractive leaves with an arrowhead shape. Certain species of Xanthosoma produce tubers that are used for food.
