Cornus is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods or cornels, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species.

Dudleya edulis is a species of perennial, succulent flowering plant of the Crassulaceae, known by the common names fingertips, lady-fingers, mission lettuce, or simply the San Diego dudleya. The common name "fingertips" denotes the finger-like shape of the leaves; the specific epithet edulis refers to the Kumeyaay people's traditional foraging and consumption of the plant's young scapes. Dudleya edulis is native to the dry, coastal cliffs and chaparral hills of Southern California and northern Baja California, where it has adapted to absorb as much moisture as possible from the nightly fog and marine layer which forms over the Pacific Ocean and gradually moves slightly inland, typically covering all plants and stationary objects in dew. In addition to its inherent drought-tolerance and xeric qualities, this species is also highly salt-tolerant, as it grows almost exclusively facing the ocean, often in exposed settings where it is subjected to regular periods of extreme wind and weather. The species may be found growing on rocky hillsides, sandstone sea cliffs, chaparral habitat, arid canyons, or rooted between exposed, bare rock crevices.
Dudleya stolonifera is a succulent plant known by the common name Laguna Beach liveforever or Laguna Beach dudleya.

It is federally listed as a threatened species of the United States.

It has an Arctic–alpine distribution; it can be found throughout the Arctic, as well as at higher elevations in the mountains of Eurasia and North America. It grows on tundra and in alpine climates where snow remains year-round, and on subalpine mountain slopes. This is a low, mat-forming perennial herb producing clumps of herbage in rocky, gravelly substrate. A spreading stem up to 15 centimeters long grows from a caudex. Each leaf is divided into usually three leaflets borne at the end of a petiole up to 7 centimeters long. Each wedge-shaped leaflet has three teeth at the tip. The flower has usually five pointed green bractlets, five wider pointed green sepals, and five tiny yellowish petals each about a millimeter long. The fruits develop in the remnants of the sepals on erect stalks.
Euphorbia pubentissima, commonly called the southeastern flowering spurge or false flowering spurge, is a species of plant in the spurge family.
