    Desert dandelion and Sacred Datura

    by JLBG Written May 15, 2005

    4.5 out of 5 starsHelpfulness

    Favorite thing: 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.

    Mohave Yucca, close-up on the fibers

    by JLBG Written May 15, 2005

    4.5 out of 5 starsHelpfulness

    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.

    by JLBG Updated May 17, 2005

    4.5 out of 5 starsHelpfulness

    Favorite thing: Teddy Bear cactus (Opuntia Bigelovii, now named (Cylindropuntia Bigelovii) is also called Jumping Cholla. You will very fast understand why the name of Jumping Cholla . As soon as you look at it, there is one that catches you ! No wonder that it is not a popular indoor plant ! Actually, the Jumping Cholla does not jump but it has so many long and soft (soft and prickling all together !) spines that though you feel you are enough away, YOU catch it. If you take care, you will be able to admire it's beautiful yellow flowers.

    Mohave Yucca in full bloom

    by JLBG Written May 15, 2005

    4.5 out of 5 starsHelpfulness

    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. Yucca contains resveratrol, a proven antioxidant. In addition, it contains a high percentage of saponins that might prevent cholesterol absorption and promote its elimination.

    Bladderpod

    by JLBG Written May 16, 2005

    4 out of 5 starsHelpfulness

    Favorite thing: Bladderpod, Isomeris arborea is an evergreen shrub, 3-4" height. This perennial plant, native to the Baja and Mohave regions of California, grows from coastal regions up to the elevation of 4000 feet. The plant produces abundant yellow flowers year round, regardless of water. The fruit forms into attractive long capsules, hence the name "Bladderpod". The plant is best left untouched because the scent is generally found unpleasant. It is also the favorite habitat of the Harlequin beetle.
