| Annual herb up to 150cm tall, native to [[https://www.worldfloraonline.org/taxon/wfo-0001023679|western North America]] from from British Columbia to northern Mexico. Plant glandular-hairy, sometimes glabrous; basal leaves elliptic to ovate, proximal clanceolate, distal narrower, reduced; flower: calyx 6-10mm, densely glandular, corolla tube 20-35mm long, pinkish-white, lobes five, white. \\ | Annual herb up to 150cm tall, native to [[https://www.worldfloraonline.org/taxon/wfo-0001023679|western North America]] from from British Columbia to northern Mexico.

| | „The emission of a single compound, [[https://www.thegoodscentscompany.com/data/rw1024231.html|benzyl acetone]] (BA, 4-phenyl-2-butanone), is barely detectable during the day in the headspace of flowers of the self-compatible disturbance species Nicotiana attenuata, but it increases dramatically (50×) in the evening, becoming the dominant component in the floral headspace.“ \\ |

| Main compounds of the floral headspace were benzylacetone (49.1%), benzyl alcohol (6.3%), benzaldehyde (6.1%), hexyl acetate (3.5%), caryophyllene (2.1%), limonene (1.4%), and cis-3-hexenol (1.0%). Minor components were e.g. geraniol (0.7%), cis-α-bergamotene (0.7%), cis-3-hexenyl butyrate (0.7%), 2-phenylethanol (0.6%), nicotine (0.4%), methyl benzoate (0.15%), and methyl salicylate (0.05%). \\ | Main compounds of the floral headspace were benzylacetone (49.1%), benzyl alcohol (6.3%), benzaldehyde (6.1%), hexyl acetate (3.5%), caryophyllene (2.1%), limonene (1.4%), and cis-3-hexenol (1.0%).
