Mohave Yucca (Yucca schidigera) is also called Adam's Needle, Bear Grass, Dagger Plant, Our-Lord's-Candle, Soapweed, Spanish Bayonet and sometimes mistaken with Joshua Tree,
It grows naturally only in Mojave and Sonoran deserts of southeastern California, Baja California, southern Nevada and western Arizona.
The flowering heads of the desert dandelion are large and showy, pale to bright yellow
The large white flower is Sacred Datura, Datura wrightii (Solanaceae family), the only one I saw in bloom. Its enormous white trumpet flowers have a sweet smell. It blooms at night starting early evening and fading before next noon. It is pollinated by nocturnal visitors, usually sphinx or hawk moths It is found in western Texas, New Mexico, Colorado, Utah, Arizona, southern California, Mexico, and the West Indies and grows within an elevation range between sea level and 6,500 feet. The name Datura, its generic name, is from the Hindu Dhatura (dhat = the eternal essence [of God])..
The tea from Datura is extremely hallucinogenic. The hallucinogenic effects are reported to be stronger than Peyote, Psyillicibin, or LSD. However, Datura is also very toxic and can be deadly. It is apparently Scopolamine that produces the hallucinogenic effects, but the Sacred Datura contains also high concentrations of highly toxic Atropine, Hyoscyamine.
When Datura is used in a Native American ritual, it is always under the guidance of an individual of certain tribal spiritual resolve such as a Medicine person or tribal elder. These experts on the use of the plant know what other plants to add in order to neutralize the harmful effects. They also know how much to administer and when and where to pick the plants, such as age, season, time of year, whether under a full moon or no moon at all. Chemical constituents and levels vary greatly from plant to plant, time of year, and from one area to another just generally, but especially so if the plants are obtained through ritual or from a spot known for having special powers, or sacred grounds. The plants are very toxic, poisonous and lethal, especially if consumed in quantities not monitored by someone versed in their safe administration.
Favorite thing: The leaves of the Mohave Yucca are highly fibrous. Native Indians made cordage (yarn) from yucca and agave, the Indians cut the leaves with a thin, saw-like stone blade. Then, using a heavy rock scraper, they stripped the flesh from the leaves, baring the fiber. Masses of fiber were twisted on a spindle whorl or rolled between hand and thigh to create long strings. Cordage was woven into fabric on looms or braided by hand and sewn.

Favorite thing: Although no well-controlled human studies have been conducted to verify them, a few animal studies and case reports suggest a limited role for oral yucca in treating both cardiovascular and high cholesterol levels.
