Coyote tobacco grows from a low cluster of leaves. It can grow tall and upright, or in a branched, shrubby form. The entire plant is sticky and often looks dirty. This native plant is considered a sensitive species in Washington State. Native Americans reported used the plant for medicinal purposes, as well as ceremonial smoking. The plant gives off an unpleasant tobacco scent when touched.
Erect, bright green, glossy, hairy and sticky.
Lower leaves are more or less spear-shaped and have smooth edges and pale midribs. The leaf stem and midrib on the underside have short, bristly hairs. Upper leaves are narrow and smaller, with similar bristles. All leaves are hairy and have glands that look like tiny white dots.
White to slightly pinkish trumpet-shaped or tubular flowers occur in clusters at the ends of the stems and along the stem where leaves meet the stem.
Grows a taproot.
Disturbed sites, dry rocky washes, well-drained slopes and other dry sites.
Annual (sprouts, flowers and dies in a single year)
Reproduces by seed
Little information is available about the control of coyote tobacco. As for all annuals, control relies on preventing production of seed. Once produced, seed remains viable for decades. Plants continue to sprout during the summer months.
Dig, hoe or pull small patches. Mowing alone does not provide control.
Encourage thick, competitive vegetation. Avoid disturbing the soil.
No information is available.
Apply broadleaf-selective herbicides such as 2,4-D on young plants. Glyphosate may also be effective but is non-selective and can kill or damage other plants, including lawn grasses.
