Perideridia howellii is a species of flowering plant in the family Apiaceae known by the common name Howell's yampah. [1] It is native to the mountains of Oregon and northern California, where it grows in moist soils, often near streams and rivers. [2] It is a perennial herb which may exceed 1.5 metres in maximum height, its slender, erect stem growing from a cluster of many narrow fibrous roots measuring up to 15 centimetres long. [2] Leaves near the base of the plant have lance-shaped blades up to half a metre long which are divided into many leaflets made up of toothed, oval segments. [2] Leaves higher on the plant are similar, but generally smaller. The inflorescence is a compound umbel of many spherical clusters of small white flowers. [2] These yield ribbed, oblong-shaped fruits each about half a centimetre long. [2]

It is also used as a southwestern landscaping plant. This is a bushy, spreading shrub approaching a maximum height of 4 metres (13 ft) with many long, thorny, tangled branches. The branches are lined with small, fleshy green leaves up to 1.5 centimetres (0.59 in) long and coated with glandular hairs. The inflorescence is a small cluster of tubular flowers roughly 1–2 centimetres (0.39–0.79 in) long including the calyx of sepals at the base. The lavender to nearly white corolla is funnel-shaped and has 2 to 6 lobes at the mouth. The five stamens and one style protrude from the flower. The fruit is a bright red spherical berry about a centimeter wide containing many seeds. The berries attract birds.

It is native to the southwestern United States, where it grows in a variety of desert and mountain habitat types. This is a bushy, erect shrub approaching a maximum height of 4 metres (13 ft) with many rigid, thorny branches. The branches are lined thickly with fleshy oval or widely lance-shaped leaves each 1–3 centimetres (0.39–1.18 in) long and coated with glandular hairs. The inflorescence is a small cluster of tubular flowers roughly 1–2 centimetres (0.39–0.79 in) long including the calyx of fleshy sepals at the base. The flower is white or greenish with lavender or green veining. The corolla is a tube opening into a face with four or five lobes.

Perideridia bacigalupii is an uncommon species of flowering plant in the family Apiaceae known by the common names Mother Lode yampah and Bacigalupi's perideridia. It is endemic to California, where it is known only from the northern and central Sierra Nevada foothills. It is a member of the flora in chaparral and pine woodlands. It is a perennial herb which may exceed 1.5 meters in maximum height, its slender, erect stem growing from tubers. Leaves near the base of the plant have blades up to 40 centimeters long which are divided into many narrow subdivided lobes. Leaves higher on the plant are smaller and less divided. The inflorescence is a compound umbel of many spherical clusters of small white flowers. These yield ribbed, oblong-shaped fruits about half a centimeter long.
Perideridia bolanderi is a species of flowering plant in the family Apiaceae known by the common name Bolander's yampah. It is native to the western United States, where it grows in many types of habitat. It is a perennial herb which may approach one meter in maximum height, its slender, erect stem growing from tubers measuring up to 7 centimeters long. Leaves near the base of the plant have blades up to 20 centimeters long which are divided into many subdivided lobes of various sizes and shapes; the terminal segments are usually lined with teeth. Leaves higher on the plant are smaller and less divided. The inflorescence is a compound umbel of many spherical clusters of small white flowers. These yield ribbed, oblong-shaped fruits about half a centimeter long. The Atsugewi and Miwok of California used the tuberous roots of this plant for food.
Perideridia kelloggii is a species of flowering plant in the family Apiaceae known by the common name Kellogg's yampah. It is endemic to California, where it is known from the north and central coasts, the San Francisco Bay Area, and the Sierra Nevada foothills.

Scrophularia lanceolata is a species of flowering plant in the figwort family known by the common names lanceleaf figwort and American figwort. It is native to North America, where it is known from western and eastern Canada and much of the United States except for the southeastern quadrant.

Amsonia kearneyana is a rare species of flowering plant in the dogbane family known by the common name Kearney's bluestar. It is native to Arizona, where there is only one native population in the Baboquivari Mountains of Pima County. There may also be a population just south of the border in Sonora, Mexico. The plant was federally listed as an endangered species in 1989. At that time the global population of the plant was made up of eight individuals in a riparian canyon. Since that time the plant has been manually propagated in an attempt to increase its numbers. Threats to the tiny native population include habitat destruction from livestock activity and flash floods in the river canyon. Many of the plants cannot reproduce because their seeds are sterile and nonviable, but this is probably due to insect predation on the seeds as they develop.
Bloomeria aurea, with common name golden stars, is a species of Bloomeria that is endemic to California. When blooming in late spring, its bright colors are distinctive.
Asparagus acutifolius, common name wild asparagus, is an evergreen perennial plant belonging to the genus Asparagus.
