This showy wildflower is native to the western United States from California to Idaho, where it is a resident of lakesides and vernal pool ecosystems.
Downingia cuspidata is a species of flowering plant in the bellflower family known by the common name toothed calicoflower. This showy wildflower is native to California, where it is a resident of ponds, meadows, and vernal pool ecosystems throughout the state. Its range may extend into Mexico.

Diplacus bigelovii is a species of monkeyflower known by the common name Bigelow's monkeyflower. It is native to the southwestern United States, where it grows in desert and slope habitats. It was formerly known as Mimulus bigelovii.
Diplacus kelloggii is a species of monkeyflower known by the common name Kellogg's monkeyflower. It is native to the mountains and foothills of northern California and southern Oregon, where it grows in bare, disturbed, and shifting substrates, such as recent rockslides and scree.
Nemacladus interior is a species of flowering plant in the bellflower family known by the common name Sierra threadplant. It is native to the Sierra Nevada of California, and it is known from Oregon as well. It grows in mountain forest habitat. It is an annual herb producing a stiff upright purple-brown stem up to about 25 centimeters tall. Small toothed oval leaves 1 to 2 centimeters long occur at the base of the plant. The inflorescence is a zigzagging series of branches bearing occasional flowers on thin pedicels. There is a single tiny bract at the base of each pedicel. The flower is a few millimeters long. It has five triangular sepals and five corolla lobes, three lobes on the upper lip and two on the lower. The corolla is white to pale purple or pink with a thin red band and yellow spot at the base of each lobe.
Puya mirabilis is a species of Bromeliad in the genus Puya. This species is native to Bolivia.
Pinguicula orchidioides is a perennial rosette-forming insectivorous herb native to Mexico and Guatemala. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 5 centimeters (2 in) long, which are covered in mucilaginous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. Uniquely among Pinguicula species from the Americas, p. orchidioides produces gemma-like basal buds which elongate into stolons and serve as a means of asexual reproduction. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single purple flowers appear between July and September on upright stalks up to 22 centimeters long.
Pinguicula elizabethiae is a perennial rosette-forming insectivorous herb native to the Mexican states of Querétaro and Hidalgo. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 5 centimeters (4 in) long, which are covered in mucilaginous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single purple flowers appear between July and October on upright stalks up to 75 millimeters long.
Proboscidea parviflora is a species of flowering plant in the family Martyniaceae known by the common names doubleclaw and red devil's-claw. It is native to the desert southwest of the United States and northern Mexico, where it grows in sandy, dry, and disturbed habitat and blooms during the hot summer. This is an annual herb growing from a taproot and producing sprawling, spreading stems. The leaves have rounded, oval, or roughly triangular blades up to 15 centimetres (6 in) long which have smooth edges or faint lobes or teeth. The inflorescence is an array of several showy bell-shaped flowers with five lobes flaring several centimeters wide. The flower is white to pink or purple, sometimes with mottling or lines of spots in the throat, and often a purple blotch on the upper lip. A yellow nectar guide extends along the lower lip. The fruit is a large seed pod many centimeters long, a cylindrical body tapering into a very long, thin, curving tail. As the fruit dries the tail cracks open and splits into two hooked, claw-like halves. The young fruits and seeds were used for food and the dark-colored hardened dry fruits were used in basketry by local Native Americans.
Delphinium viridescens is a species of flowering plant in the buttercup family known by the common name Wenatchee larkspur. It is endemic to central Washington state in the United States, where it occurs in the Wenatchee Mountains in Chelan and Kittitas Counties.
Cicuta bulbifera, commonly known as the bulb-bearing water-hemlock, is a plant native to North America and one of four species in the poisonous genus Cicuta. Tiny bulbils form in the leaf joints in the upper part of the plant, giving the plant its scientific and common names. Cicuta bulbifera can be distinguished from Cicuta douglasii by its narrow leaflet segments and its bulbil-bearing upper leaf axils.
Agalinis paupercula, commonly known as the smallflower false foxglove, is a hemiparasitic annual plant native to the eastern parts of the United States and Canada. Found in open, moist areas, its purple flowers are borne on a 30-to-70-centimeter stem, and bloom in August and September. The species has often been treated as a variety of Agalinis purpurea, the purple false foxglove, and preliminary genetic evidence suggests that the two are, in fact, a single species.
Asplenium × gravesii, commonly known as Graves' spleenwort, is a rare, sterile, hybrid fern, named for Edward Willis Graves (1882–1936). It is formed by the crossing of Bradley's spleenwort (A. bradleyi) with lobed spleenwort (A. pinnatifidum). It is only found where its parent species are both present; in practice, this proves to be a few scattered sites in the Appalachian Mountains, Shawnee Hills, and Ozarks, reaching perhaps its greatest local abundance around Natural Bridge State Resort Park. Like its parents, it prefers to grow in acid soil in the crevices of sandstone cliffs.
Holmgrenanthe petrophila is a rare perennial desert plant in the plantain family (Plantaginaceae), and the sole species of the genus Holmgrenanthe. It forms low mats of branched stems growing from a woody base. The leaves have small spines along their edges. The solitary yellow flowers are tubular with five free lobes at the end, the upper two pointing backwards, the lower three projecting forwards. The species is known only from about ten locations, most in the Titus Canyon and the adjacent Fall Canyon, all within the Californian section of Death Valley National Park. It grows in limestone crevices on the canyon walls, often on the north face.
Pedicularis sylvatica, commonly known as common lousewort, is a plant species in the genus Pedicularis. It is native to central and northern Europe where it grows on moist acidic soils, moorland, grassy heathland and the drier parts of marshes.
Kalanchoe sexangularis, also known as bushveld kalanchoe, six-angled kalanchoe, or red-leaved kalanchoe, is a species of the succulent genus Kalanchoe, in the family Crassulaceae that is native to Southern Africa.
Macodes sanderiana(Kraenzl.) Rolfe is a species of South East Asian jewel orchid mostly recorded from New Guinea but is also found in the Solomon Islands and Vanuatu. This species has a long history of cultivation in Europe since the early 20th century and is prized for its ornamental leaves which are the largest in its genus. The leaves are dark green, the upper surface covered in an intricate network of veins in colors ranging from bright green to copper. In contrast, flowers are small and pallid so are often removed in cultivation. In nature, M. sanderiana grows in rainforests on the forest floor or lithophytically out of rock crevices. This species survives at a broad range of altitudes from close to sea-level, up to the lower boundary of the cloud forest. Exudates from the leaves of this orchid are traditionally used in New Guinea as eye drops for the treatment of myopia. M. sanderiana has not been assessed for the IUCN red list, however, as recently as the 1980’s this species was common in parts of its range within New Guinea.
