Superbloom
A superbloom is a rare desert botanical phenomenon in California in which an unusually high proportion of wildflowers whose seeds have lain dormant in desert soil germinate and blossom at roughly the same time. The phenomenon is associated with an unusually wet rainy season. The term may have developed as a label in the 1990s. Necessary conditions and sequence of events The conditions under which a superbloom can occur are exceptional. Because some invasive grasses, such as bromes, will compete with native flowers for moisture, the desert must remain dry enough prior to the bloom to keep them from becoming established. The desert must receive rainfall in the autumn, and this rain must penetrate deep into the soil matrix in order to reach a majority of the dormant seeds of flowering plants. If subsequent rainfall is excessive or inundating, the young plants may be carried away in flash floods; if it is inadequate, the seeds will die from dehydration. Next, the ground in whi ...

Carrizo Plain
The Carrizo Plain ( Obispeño: ''tšɨłkukunɨtš'', "Place of the rabbits") is a large enclosed grassland plain, approximately long and up to across, in southeastern San Luis Obispo County, California, about northwest of Los Angeles. It contains the Carrizo Plain National Monument, and it is the largest single native grassland remaining in California. It includes Painted Rock in the Carrizo Plain Rock Art Discontiguous District, which is listed on the National Register of Historic Places. In 2012 it was further designated a National Historic Landmark due to its archeological value. The San Andreas Fault occurs along the eastern edge of the Carrizo Plain at the western base of the Temblor Range. Geography and geology The Carrizo Plain extends northwest from the town of Maricopa, following the San Andreas Fault. Bordering the plain to the northeast is the Temblor Range, on the other side of which is California's Central Valley. Bordering the plain to the southwest is th ...

Wildflower
A wildflower (or wild flower) is a flower that grows in the wild, meaning it was not intentionally seeded or planted. The term implies that the plant probably is neither a hybrid nor a selected cultivar that is in any way different from the way it appears in the wild as a native plant, even if it is growing where it would not naturally. The term can refer to the flowering plant as a whole, even when not in bloom, and not just the flower. "Wildflower" is not an exact term. More precise terms include ''native species'' (naturally occurring in the area, see flora), ''exotic'' or, better, ''introduced species'' (not naturally occurring in the area), of which some are labelled ''invasive species'' (that out-compete other plants – whether native or not), ''imported'' (introduced to an area whether deliberately or accidentally) and ''naturalized'' (introduced to an area, but now considered by the public as native). In the United Kingdom, the organization Plantlife International in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hesperocallis Undulata
''Hesperocallis'' is a genus of flowering plants that includes a single species, ''Hesperocallis undulata'', known as the desert lily or ajo lily. It is found in the desert areas of southwestern North America, in Northwestern Mexico, California, and Arizona. The plant grows in Mojave Desert and Sonoran Desert habitats. Taxonomy In the APG III system, adopted here, ''Hesperocallis'' is placed in the family Asparagaceae, subfamily Agavoideae, since recent molecular systematic studies (Pires et al. 2004) have confirmed a close relationship with ''Agave''. Other classifications have included the species in its own family, Hemerocallidaceae, or placed it in the Hostaceae (Funkiaceae); both families are submerged into the Agavoideae in the APG III system. As with many of the 'lilioid monocots', prior to the use of molecular evidence in classification, it was placed in the Liliaceae. Uses The bulbs of the desert lily are eaten by native peoples.

Desert Sunflower
''Geraea canescens'', commonly known as desert sunflower, hairy desert sunflower, or desert gold, is an annual plant in the family Asteraceae. The genus name comes from the Greek ''geraios'' ("old man"), referring to the white hairs on the fruits. ''G. canescens'' bears yellow sunflower-like flowers on slender, hairy stems. It grows high. The leaves are gray-green and grow to long. It flowers February through May after sufficient rainfall, and sometimes in October and November. The flowers are wide with 10–20 ray florets, which are each about long. The plant is native to western North America, specifically Arizona, Nevada, California, and Utah. A drought-resistant annual plant, it can be found in the California, Mojave, and Sonoran Deserts. It grows below sea level, from , in sandy desert soils along with creosote bush (''Larrea tridentata''). It is one of the flowers which participates in the occasional superblooms of desert flowers. There are two varieties: *''Geraea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evening Primrose
''Oenothera'' is a genus of about 145 species of herbaceous flowering plants native to the Americas. It is the type genus of the family Onagraceae. Common names include evening primrose, suncups, and sundrops. They are not closely related to the true primroses (genus ''Primula''). Description The species vary in size from small alpine plants 10 centimeters tall, such as ''O. acaulis'' from Chile, to vigorous lowland species growing to 3 meters, such as ''O. stubbei'' from Mexico. The leaves form a basal rosette at ground level and spiral up to the flowering stems. The blades are dentate or deeply lobed (pinnatifid). The flowers of many species open in the evening, hence the name "evening primrose". They may open in under a minute. Most species have yellow flowers, but some have white, purple, pink, or red. Most native desert species are white. ''Oenothera caespitosa'', a species of western North America, produces white flowers that turn pink with age. One of the most distincti ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Lupinus
''Lupinus'', commonly known as lupin, lupine, or regionally bluebonnet etc., is a genus of plants in the legume family Fabaceae. The genus includes over 199 species, with centers of diversity in North and South America. Smaller centers occur in North Africa and the Mediterranean. They are widely cultivated, both as a food source and as ornamental plants, but are invasive to some areas. Description The species are mostly herbaceous perennial plants tall, but some are annual plants and a few are shrubs up to tall. An exception is the ''chamis de monte'' (''Lupinus jaimehintoniana'') of Oaxaca in Mexico, which is a tree up to tall. Lupins have soft green to grey-green leaves which may be coated in silvery hairs, often densely so. The leaf blades are usually palmately divided into five to 28 leaflets, or reduced to a single leaflet in a few species of the southeastern United States and eastern South America. The flowers are produced in dense or open whorls on an erect spik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
