Rosa californica | |
Rosa californica, the California wildrose, [1] or California rose, is a species of rose native to the U.S. states of California and Oregon and the northern part of Baja California, Mexico. The plant is native to chaparral and woodlands and the Sierra Nevada foothills, and can survive drought, though it grows most abundantly in moist soils near water sources. [2] [3]
This thorny, flowering, fruit-bearing shrub is also deciduous, and grows vertically up to six feet tall. [4] [5] The meaning of its name is twofold; Rosa, that it resembles or is composed of roses, and californica, that it originates from California. [4]
Rosa californica is a bush or thicket-forming shrub with prickly, curving stems. The fragrant flowers may grow singly or in inflorescences of several blooms. Each rose is open-faced and generally flat, with five petals in any shade of pink from almost white to deep magenta. The five smooth petals and sepals have a bowl-like bloom, semi-inferior ovaries, and compound veiny and hairy leaves. [4] [5] R. californica also bears fruit called "rose hips," which contain yellow seeds. [2]
Rosa californica is a common plant native to California. It is primarily found in elevations of below 6,000 feet. While most common in moist regions like river banks, the plant can also adapt to various soil textures, develop drought resistance, and has common-pest and disease resistance. [4] [6] [7]
Rosa californica competes with other vegetation in moist environments because of its lateral spreading rhizomes (horizontally-spreading underground roots) and above-ground, thorny stems. Moreover, the wildroses' stems and shoots can be cut, but will regrow from submerged rhizomes. Thus, R. californica may develop thickets [4] and overwhelm "desirable vegetation" under improper management. However, it does not pose a foreseeable environmental concern. [6]
Rosa californica is used in California native gardens and habitat gardens, forming colonies, and attracting wildlife with the bright rose hips in autumn. [8] Hard, dry internal seeds can be extracted by hand from mature, bright red hips. The wildrose can also be propagated with stem or rhizome cuttings. [6]
Rosa californica is readily acclimated. Its natural propagation helps restore damp areas. Subterranean stems stabilize the surrounding earth. Thorny thickets offer ground cover, shelter, and even nests for organisms. [6]
R. californica's open flowers and nectar attract insects and pollinators. Its lengthened spring to fall blooming period [4] offers food for local bees. R. californica's fruits also persist on thickets through the forage-scarce winter, [5] serving as food for bugs, birds, and hoofed mammals like deer and elk. [6] [7]
The wildroses' hips are related to the Rosaceae family's apricots, apples, and roses. [7] They are fragrant, edible, and look and taste like "small apples." [4] Some indigenous California tribes eat R. californica's hips raw and use the stems and fibers for crafts like coiled baskets, jewelry, and decoration. Other tribes leverage the roses' medicinal properties. They used a mix of rose petals, leaves, and/or rose "hips" in drinks or as medicine to relieve skin and general inflammation, pain, and illness (including fever, stomach pains, and sores). [5] [6] [7]
The rose hips were used during World War II for their high vitamin content. They are dried for tea, or for use in jellies and sauces. The Cahuilla eat the rose buds raw or soaked them in water for drinking. A tea was also made from the roots, and used for colds. Because the rose hips remain on the plant throughout the winter, they provide food for wildlife during times when little forage is available. [9]
Viola pedunculata, the California golden violet, Johnny jump up, or yellow pansy, is a perennial yellow wildflower of the coast and coastal ranges in California and northwestern Baja California. The common name "Johnny jump up" is usually associated with Viola tricolor however, the introduced garden annual.
Salvia spathacea, the California hummingbird sage, hummingbird sage, or pitcher sage, is a species of flowering plant in the family Lamiaceae, native to southern and central California growing from sea level to 610 m (2,001 ft). This fruity scented sage blooms in March to May with typically dark rose-lilac colored flowers. It is cultivated in gardens for its attractive flowering spikes and pleasant scent.

It is native to the Transverse and Peninsular Ranges and the South Coast regions of Southern California. This extends from Santa Barbara County and the Channel Islands to San Diego County and extending into north-central Pacific coastal Baja California and its offshore islands such as Cedros Island.

It can be found in nearly all US states and Canadian provinces east of the Great Plains. It is common throughout its range and can be found in a wide variety of open habitats, from thickets and open woods to roadsides and along railroads.

Rhinotropis californica, synonym Polygala californica, is a species of flowering plant in the milkwort family known by the common name California milkwort. It is native to southwestern Oregon and northern and central California, where it grows in the coastal mountain ranges in local habitat types such as chaparral and forest. It is a perennial herb producing spreading stems, generally decumbent in form, up to about 35 centimeters in maximum length, lined with narrow oval leaves each a few centimeter long. The upper inflorescences produce several open flowers, and there may be some closed, cleistogamous flowers lower on the plant. The open flowers have pink or white winglike lateral sepals with hairy edges. The petals are similar in color, the central one tipped with a white or yellow beak. The fruit is a flattened green capsule up to a centimeter long containing hairy seeds.
Rosa pisocarpa is a species of rose known by the common name cluster rose or swamp rose. It is native to western North America from British Columbia to northern California, where it generally grows in moist habitats. It is a shrub sometimes forming a thicket, and growing up to 2.5 meters tall. The stems can be dark red or blackish and are often studded with straight, paired prickles at nodes. The leaves are each made up of several toothed oval leaflets, the terminal leaflet up to 4 centimeters long.

The hips are pear- or egg-shaped and borne in clusters, and are decorative in fall and early winter, when they are red or reddish-purple and contrast with yellow foliage. Fall foliage can be yellow or dark red.
