It is an annual or limited perennial herbaceous plant, covered in glandular hairs; The root is thick and sturdy. The stem is 0.7 to 2 meters high, with slightly lignified base. The leaves are oblanceolate, oblanceolate, oblanceolate, or ovate in shape, with the tip gradually pointed and the base gradually narrowed until the stem is ear shaped and half clasped. Inflorescence terminal, paniculate, multi flowered; The pedicel is 5-20 millimeters long. The capsule is ovoid or rectangular in shape, approximately equal in length to the persistent calyx. The seeds are circular or broadly rectangular, with a diameter of about 0.5 millimeters and are brown. Blooming and fruiting in summer and autumn. Native to South America. Widely cultivated in various provinces and regions of northern and southern China. Tobacco is a warm loving crop that is sensitive to temperature, and different temperature conditions have a significant impact on the quality and yield of tobacco. The temperature requirements for high-quality tobacco during its growth period are lower in the early stage and higher in the later stage. Used as raw materials for the tobacco industry; The entire plant can also be used as a pesticide insecticide; It can also be used medicinally as an anesthetic, sweating, sedative, and emetic. Annual or limited perennial herbs, all covered with glandular hairs; The root is thick and sturdy. The stem is 0.7 to 2 meters high, with slightly lignified base. The leaves are oblanceolate, oblanceolate, oblanceolate, or ovate in shape, with an apex gradually pointed, and a base gradually narrowed until the stem is ear shaped and half clasped. They are 10 to 30 (-70) centimeters long and 8 to 15 (-30) centimeters wide, with an inconspicuous or winged stalk. Inflorescence terminal, paniculate, multi flowered; The pedicel is 5-20 millimeters long. Calyx tube shaped or tube shaped bell shaped, 20-25 mm long, lobes triangular lanceolate, varying in length; The corolla is funnel-shaped, light red, with a lighter color on the tube, slightly curved, 3.5 to 5 centimeters long, and the eaves are 1 to 1.5 centimeters wide, with sharp lobes; One stamen is significantly shorter than the other four, does not protrude from the throat of the corolla, and the base of the filament is hairy.
