White, Cream

datura plant
DATURA - Solanaceae/potato family.  All parts of the datura plant are poisonous and can be fatal if ingested.  Large, white, trumpet-shaped flowers bloom March through November.  Corollas are up to 6 inches long, have 5 teeth, often tinged with purple or lavender around the margins.  This flower opens after dusk and closes by mid-morning of the following day.
joshua tree
JOSHUA TREE - Yucca brevifolia/lily family.  Mormon pioneers named the species for the biblical figure Joshua, because the trees uplifted limbs reminded them of Joshua praying and pointing to the heavens.  Joshua trees grow best at  elevations between 2,000 and 6,000 feet.  Like other yucca, Joshua trees are only pollinated by a specific species of yucca moth, so each is dependent on the other for survival.  Clusters of cream-colored flowers appear March to May at the branch tips.
Yucca Lord's Candle
YUCCA, LORD'S CANDLE - A species of flowering plant closely related to the genus Yucca.  Native to California and Baja California where it mainly occurs in chaparral, coastal sage scrub and oak woodland plant communities.  It produces a stemless cluster of long, rigid sawtoothed leaves, usually gray-green in color, ending in a sharp point.   This plant takes several years (usually 5+) to reach maturity and flower, at which point it usually dies.  Most subspecies produce offshoots from the base, so that although the parent plant dies, a cluster around the base continue to grow and reproduce.  It can often survive wildfires, even after being scorched, and grows back.  The flowers appear on a long stem around April and May.

mojave yucca plant
YUCCA, MOJAVE - yucca shedigera,  Lz'liaceae/ Lily family.  These usually grow 6-l2 feet tall; the leaves can be up to 4 feet long, and the flower head up to 2 feet long.  Native Americans have used this plant in many ways.  The roots made a soap substitute.  Flowers, fruits and seeds were eaten.  Leaf edge fibers were used for bowstrings and rope, and leaf fibers were made into sandals and baskets.  The yucca and the Tegiticula moth have a symbiotic relationship; neither could survive without the other.  The moth pollinates the flower then lays its eggs in the ovary of the flower.  The larvae develop and eat some of the seeds.  Some are left for animals, and some develop into  new plants.  The waxy, cream-colored flowers bloom in April and May.
