Sacred datura, Southwestern thorn apple, western Jimson weed
From California, west to Texas
Canyons and washes, open plains; sandy, well drained locations
Ovate, dark green, with irregularly lobed or wavy edges and prominent, lighter-colored veins. Up to 5 inches across and 10 inches long
Datura wrightii produces probably the largest flowers in the west; a tubular white corolla up to 8 inches long, opening to five fused lobes about 4 inches across, each with a thin, narrow, tooth-like projection. The outer edges of the lobes have a pinkish tint, while the bases, and the inside of the corolla tube, are green. Buds are also pinkish, or dull purple. Blooms usually open during the night and start to wither before noon. The plant produces a dense mass of large, dark green leaves which have a very fine downy hair covering and exude a bad smell. The flowers have a pleasant aroma, however. This is a poisonous species, historically used by native tribes as an anesthetic and a hallucinogen.
