Nicotiana attenuata là loài thuộc chi wild tobacco, thường được biết đến là coyote tobacco. Đây là một loài hoang dại mọc ở miền Tây Bắc Châu Mỹ, từBritish Columbia tới Texas và Bắc Mexico. Đây là loài thường niên, cao lớn nhất khoảng 1 mét. Lá rộng, có thể tới 10 cm dài. The lower ones oval and the upper narrower in shape, and are borne on petioles. The inflorescence bears several flowers with pinkish or greenish white tubular throats 2 to 3 centimeters long, their bases enclosed in pointed sepals. The flower face has five mostly white lobes. The fruit is a capsule about a centimeter long.
This plant was used for a great variety of medicinal purposes by many Native American groups, and was smoked ceremonially by the Hopi, Apache, Navajo, Paiute, and other groups.[1]
When this tobacco is eaten by the larvae of the tobacco hornworm (Manduca sexta) the plant emits green leaf volatiles that attract Geocoris bugs, which are predators of the worm.[2]
