Consolida is a genus of about 40 species of annual flowering plants in the family Ranunculaceae, native to western Europe, the Mediterranean and Asia. Phylogenetic studies show that Consolida is actually an annual clade nested within the genus Delphinium and it has been treated as a synonym of Delphinium in Kew's Plants of the World Online.
Delphinium bakeri, or Baker's larkspur, is a species of perennial herb in the buttercup family, Ranunculaceae.

Delphinium patens is a species of larkspur known by the common names zigzag larkspur and spreading larkspur. It is a wildflower limited mainly to California. Though not yet confirmed there, it is expected in Baja California. Plants grow typically 20 to 50 centimeters tall and bear up to 36 flowers each. The stems are mostly hairless, have reddish bases, and bears leaves on the lower half. Each leaf is divided into 3 to 9 lobes. The flower has dark blue sepals, the latter ones reflexed. The spur at the back of the flower is 4 to 8 millimeters long. The cleft at the center of the flower has white or yellowish scattered hairs. The elongated fruit is one or two centimeters long and contains pitted seeds.

Delphinium cardinale is a species of larkspur known by the common names scarlet larkspur and cardinal larkspur. This wildflower is native to California and Baja California, where it grows on coastal, inland, and desert chaparral slopes, such as the Colorado Desert, and the Peninsular and Transverse Ranges. The presence of diterpenoid alkaloids, probably including the highly toxic methyllycaconitine, in above-ground parts of D. cardinale means that they are likely to be toxic if ingested.
Delphinium decorum is a species of larkspur known by the common names coastal larkspur and yellow-tinge larkspur. This wildflower is native to California and Oregon, where it grows on the slopes of the coastal ranges from the San Francisco Bay Area north to the southern Oregon coast. It has an erect stem which approaches half a meter in height at maximum. The leaves, which are divided into a number of narrow lobes, are mostly located about the base of the plant. The spindly stem above bears two to twenty widely spaced flowers. Each flower is carried on a pedicel several centimeters long. The five long, flat sepals are extended to give the face of the flower a star shape, and they are usually deep blue to purple. The petals are similar in color, except the top two may be lighter to almost white. The spur is very thin and may be nearly two centimeters long.
Delphinium depauperatum is a species of larkspur known by the common names slim larkspur and dwarf larkspur. This wildflower is native to western North America where it is found in mountain meadows. It grows from a short root and erects a stem usually under 40 centimeters in maximum height. The small leaves are divided into lobes and are usually located about the base of the plant. Toward the top of the stem are flowers on long pedicels, with usually not more than 20 flowers per plant. The flowers generally have deep dark blue sepals which are flat and extended to the sides, and petals which are mainly the same color except for the top two, which may be lighter blue to white. The spur is between one and two centimeters long.
Delphinium glaucum, known by the common names Sierra larkspur, mountain larkspur, and glaucous larkspur, is a species of wildflower in the genus Delphinium, which belongs to the buttercup family, Ranunculaceae. It is native to western North America from Arizona to Alaska, growing in moist mountainous environments such as riverbanks and meadows.
Delphinium hansenii is a species of larkspur known by the common names Eldorado larkspur and Hansen's delphinium. It is endemic to California, where it grows in mountains, valleys, and desert from the southern Cascade Range to the Mojave Desert. This wildflower usually grows between one half and one meter in height, although it can grow much taller. The deeply lobed leaves are hairy, especially on the undersides. The inflorescence has usually over 25 flowers grouped close together at the top of the stem and held on long pedicels. The flowers are white to light blue or light pink, or bicolored, and vary in size. The inner petals may be quite hairy.
Delphinium hesperium is a species of larkspur known by the common name foothill larkspur. It is also sometimes called western larkspur and coastal larkspur, but these names are less specific since other species share them. It is endemic to California, where it grows in woodland and grassland in the northern half of the state. This wildflower generally reaches one half to one meter in height. It has deeply lobed, prominently veined leaves, mostly located near the base of the plant. The inflorescence may hold very few to over 100 flowers, each on a long, thick pedicel. The flowers are usually a brilliant blue or purple, and sometimes lighter pinkish to white. Often the sepals are dark in color and the petals lighter. The spur is about one to two centimeters long.
Delphinium hutchinsoniae is a rare species of larkspur known by the common names Monterey larkspur and Hutchinson's larkspur. It is endemic to California, where it is known only from Monterey County. This wildflower reaches a meter in height but is usually shorter. The leaves are divided into lobes which are further divided into smaller lobes, and they are mostly located low on the plant. The top of the thin, erect stem is occupied by an inflorescence of not more than ten flowers. Each flower has sepals which are brilliant purple or blue to lavender, two petals which are the same color, and two upper petals which are usually white. The spur is up to two centimeters long and curves down at the tip.
Delphinium nuttallianum is a species of larkspur known by the common names twolobe larkspur, Nuttall's larkspur, and common larkspur. It is widely distributed across western North America from California to Alberta, including mountain meadows and the majority of the sagebrush steppe, except very dry areas.
Delphinium recurvatum is a species of larkspur known by the common names Byron larkspur, recurved larkspur, and valley larkspur. It is endemic to California, where most of its historical range is in the Central Valley. The grasslands of the valley have been mostly claimed for development and agriculture, so this species is now uncommon. This wildflower reaches a maximum height of about half a meter. Its deeply lobed leaves are mainly basal, with those located further up the dark purple stem being much smaller. The flowers are generally blue, with the sepals and lower petals darker than the upper petals. The sepals are usually curved back, the trait which gives the plant its name.
Delphinium trolliifolium is a species of larkspur known by the common names poison delphinium, cow poison, and Columbian larkspur. It is native to Washington, Oregon, and northern California. This wildflower reaches one half to just over one meter in height. It has large, shiny, deeply lobed leaves. The top half of the stem is an inflorescence of widely spaced flowers on long pedicels, the longest over nine centimeters long. The flowers are usually deep brilliant blue. The upper two petals may be milky white. The spur exceeds two centimeters in length in the largest of the flowers. This plant is toxic as suggested by the common names, but most larkspur species are toxic to some degree.
Delphinium variegatum is a species of larkspur known by the common name royal larkspur. It is endemic to California, where it grows in mountains, valley and coast in woodlands and grasslands. On the forest floor of California oak woodlands typical plant associates are Calochortus luteus, Cynoglossum grande and Calochortus amabilis.
