Superbloom At Carrizo 2017
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 ...

Castilleja Exserta
''Castilleja exserta'' (formerly ''Orthocarpus purpurascens'') is a species of plant in the genus ''Castilleja'' which includes the Indian paintbrushes. Its common names include purple owl's clover, escobita, and exserted Indian paintbrush. This species is native to the Southwestern United States in various habitats of California, Arizona, and New Mexico; and to Northwestern Mexico. It is an introduced species in Hawaii. Description ''Castilleja exserta'' is an annual herb about tall with a hairy stem covered in thready leaves. Like other related ''Castilleja'' plants, this species is a hemiparasite, deriving some of its nutrients directly from the roots of other plants by infiltrating them with haustoria. As a result, its own leaves are small and reduced. Although this species is variable in appearance and easily hybridizes with other ''Castilleja'' species, it generally bears a brightly colored inflorescence of shaggy pink-purple or lavender flowers.

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 ...

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.

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 ...
