Desert Tobacco (Nicotiana obtusifolia)
Plant showing mix of last-year stems and current-year leaves and flowers

General: Desert Tobacco (Nicotiana obtusifolia) is an upright herbaceous shrub with relatively large leaves for a desert plant (to 4 inches), upper cauline leaves sessile, somewhat clasping. Flowers are white and tubular, and they produce urn-shaped capsules. The flowers are about 1-inch long (shorter than other species) and open during the day (others close during the day). The entire plant is sticky glandular.

Compare with Coyote Tobacco (Nicotiana attenuata), which is taller, has longer flowers (that close during the day), and has narrower upper leaves that are petioled (do not clasp the stem). This plant is only slightly sticky.

Desert Tobacco is an uncommon component of vegetation communities on well-drained sandy, gravelly, and rocky soils on upper bajadas and moderate slopes in the Upper Sonoran (Mojave Desert Scrub) life zone.

Family: Nightshade (Solanaceae).

Other Names: Nicotiana trigonophylla.
