Datura innoxia is quite similar to D. metel, to the point of being confused with it in early scientific literature. D. metel is a closely related plant, believed until recently to be of Old World provenance (though now thought to have been brought to Asia from the Antilles no earlier than the sixteenth century) and misconstrued as being referred to in the works of Avicenna in eleventh century ...
Veratrum californicum (California corn lily, white or California false hellebore) is an extremely poisonous plant [1] native to western North America, including the Sierra Nevada and Rocky Mountains, as far north as Washington and as far south as Durango; depending on latitude, it grows from near sea level to as high as 11,000 feet.
This plant is a serious noxious weed of agricultural fields and a colonizing invasive plant in wild lands in parts of Australia and California, [8] where it was first introduced as an ornamental shrub for its prolific white flowers.

California poppy. This is a list of San Francisco Bay Area wildflowers. The San Francisco Bay Area is unusual, for a major metropolitan area, in having ready access to rural and wilderness areas, as well as major urban parks.

California also has 1,023 species of non-native plants, some now problematic invasive species such as yellow starthistle, that were introduced during the Spanish colonization, the California Gold Rush, and subsequent immigrations and import trading of the 18th, 19th and 20th centuries.
The stems of Sisyrinchium bellum can grow as long as 60 centimetres (24 in), though they are often shorter. Its leaves are grassy and tufted. The flowers are 1–2 centimetres (0.39–0.79 in) in diameter and purplish-blue, varying somewhat in color from a true blue to a definite purple; occasional white-flowering plants are found.

The bulbs begin to grow as soon as they are planted, with flowers appearing in 3–4 weeks. Narcissus papyraceus thrives in moist, peat moss based potting mix. Plants can also be grown in containers of water. Cool temperatures between 50–65 °F (10–18 °C) and indirect light will help to prolong the bloom time. [4] [5]
