Claytonia sibirica (Siberian Spring Beauty, Siberian Miner's Lettuce, Candy Flower or Pink Purslane) is a flowering plant in the family Montiaceae, native to Siberia and western North America. A synonym is Montia sibirica. The plant was introduced into the United Kingdom by the 18th century where it has become very widespread. It is found in moist woods. It is short-lived perennial or annual with hermaphroditic flowers which are protandrous and self-fertile. The numerous fleshy stems form a rosette and the leaves are lanceolate. The flowers are 8-20 mm diameter, with five white, candy-striped, or pink petals, flowering is between February and August. The Stewarton flower.

Chaparral clematis (Clematis lasiantha) is a vine with profuse small white blooms followed by fluffy attractive seed heads.  Chaparral clematis is in the buttercup family that is native to the north-central Pacific coast and up to the western foothills of the Sierra Nevada. It grows on hillsides, in chaparral, and in open woodland.

The flowers attract butterflies.

Gardeners value chaparral clematis for its long flowering season, nearly six months in spring and summer. The rich texture of its leaves is another benefit.  It is easy to grow, and grows fast up to 15 feet. It will adorn a fence, an arbor or a pergola or wind through shrubs and trees.

Virgin's bower (Clematis ligusticifolia) is a climbing, spreading vine with showy flowers. It is also known as Old-man's Beard and Yerba de Chiva, and Virgin's bower (though this may also refer to C. lasiantha). It is native to North America and widespread across the western United States in streamside thickets, wooded hillsides, and coniferous forests up to 4,000 feet. It was called "pepper vine" by early travelers and pioneers of the American Old West. 

Clematis pauciflora is a species in the Ranunculaceae (Buttercup) family known by the common name Small Leaved Clematis. This flowering plant is native to the chaparral slopes of southern California and Baja California, from the coast to the high desert. It is a woody vine with nodes every few centimeters which produce leaves and flowers. The leaves are made up of several dark green lobed leaflets, each one to three centimeters wide. From each leaf-bearing node grows a flower cluster of one to three flowers with narrow petal-like sepals in shades of light yellow. Most of the flower is made up of a spray of up to 50 stamens and almost as many similar-looking pistils. The fruit is an achene equipped with a long plumelike style. This plant is usually found growing up through larger chaparral shrubs.

Bladderpod (Cleomella arborea) is a very fast-growing densely-branching shrub with abundant bright-yellow flower clusters at the ends of its stem branches. It can grow to 1 ½ - to 6 ½ -feet tall and 6 feet wide. The fruit is a large, papery, lantern-like capsule that is smooth and green when new, aging to light brown. This is the “bladderpod” for which the plant is named. A typical flower cluster bears a number of unopened flower buds at its tip, open flowers, and  maturing fruits. The leaves are light green.  The flowers stay on the plant most of the year and are highly fragrant, though opinion is divided on whether the scent is pleasant or unpleasant.

Bladderpod is one of the easiest California natives to grow. This tough plant does well even on south-facing slopes, alkaline soils, and salty conditions. It tolerates weekly summer water but can also get by with only natural rainfall. It is easy to grow from seeds and readily self seeds; once you have a few mature plants in your garden, expect new seedlings to pop up each winter.

It is deer resistant and attracts bees, butterflies and hummingbirds. It particularly attracts harlequin beetles which eat the leaves. If they become a problem, they can be removed by hand or sprayed off with a garden hose. It is usually not possible to eliminate them entirely.

This variety of bladderpod is the most common plant in the Peritoma genus in the foothills of the Central Valley but also occurs elsewhere. It is distinguished by inflated or nearly spheric fruits. Sometimes younger fruit is obovoid.

Clinopodium chandleri is a rare native perennial herb in the Lamiaceae (Mint) family that grows in Southern California and northern Baja, primarily in the Peninsular Range region. It tends to grow in rocky slopes, at elevations of 1,700-2,300 feet. It was formerly classified in the genus Satureja, and some sources still refer to it by that name. It is a low-growing, fragrant, spreading herb that prefers regular water and some shade. It is well suited for containers. Although it is native to mountain areas, it can be grown near the coast.

Spanish for 'good herb', Yerba Buena (Clinopodium douglasii) is a creeping evergreen perennial commonly used as a groundcover, rock garden, and container plant. A member of the Mint family, Yerba Buena's small, delicate leaves and tiny white flowers have a pleasant fragrance. The leaves are used in tea, traditional medicine, cooking, and essential oils.

This plant roots itself as it spreads, forming low mats that can be encouraged by pinching the stems. Yerba Buena grows best when planted in full or part shade. It is a low- to moderate- moisture plant that adapts to different soil types, as long as drainage is good. Plant under trees or in shady spots mixed in with taller shade-loving plants.

Monkey Flower Savory is a rare native perennial herb in the Lamiaceae (Mint) family that grows in the Coast Ranges from Monterey southward to the Transverse Range. The majority of its population lies within the Los Padres National Forest. It is uncommon throughout its range and for this reason it is included on CNPS list 4.2. It tends to grow in moist places, at elevations from 400 to over 5,000 feet. Like others in this genus, it is low-growing and delicate in appearance, but older specimens in the wild can attain nearly 2 meters. It is herbaceous with slender stems but occasionally woody at the base. The flowers are small, hairy, with a rounded-toothed margin. The tubular flowers are red-orange and grow to 1-2 inches. Hummingbirds love them! Overall, it resembles an Epilobium but requires more moisture. It spreads by rhizomes wherever there is adequate moisture.

Cneoridium is a monotypic genus in the Rutaceae (citrus family) which contains the single species Cneoridium dumosum, known by the common name Bushrue. This is an aromatic is shrub native to the coastal bluffs of southern California and Baja California. This highly-branched shrub may exceed a meter in height and sprawl about as wide. Its twigs are covered in small linear green leaves and flowers in clusters of one to three. Each flower is just over a centimeter wide with four or five rounded white petals and eight yellow-anthered white stamens. The bunching fruits are round reddish-green berries about half a centimeter wide covered in a thin peel which is gland-pitted like that of a common citrus fruit. Each berry contains one or two spherical seeds. May cause dermatitis in some people so use with caution. In the summer, the leaves of the plant turn an attractive golden color.

This is a tough and easy to grow plant. Amazingly drought tolerant but still tolerates occasional summer water better than most plants. It prefers full sun, and tolerates a wide variety of soil types. In the summer, its leaves turn an attractive golden color, and will green back up after the rainy season begins.

Coleogyne is a monotypic genus in the rose family containing the single species Coleogyne ramosissima, which is known by the common name blackbrush. This thorny, aromatic shrub is native to the deserts of the southwestern United States. It is a thickly branched thicket which may spread across the ground in clumps or grow erect to approach two meters in height. It is drought-deciduous, such that its branches are covered in clumps of fuzzy thick leaves until the hottest, driest parts of the desert year when it drops some of its foliage and becomes dormant for the season. This plant forms vast monotypic stands across the desert floor and on scrubby slopes. Flowering is triggered by a heavy spring rain in this desert-adapted species. The leathery flowers grow at the ends of small stems. They are encased in thick, fuzzy sepals which are yellow inside and reddish or orange on the outer surface. There are no petals, but the sepals remain after the flower opens, surrounding the patch of whiskery stamens and the central pistil. The fruit is an achene a few millimeters long. The plant reproduces from seed, but very rarely. The seeds do not disperse well and seedlings do not survive in large numbers. A narrow range of temperature and moisture is required for the reproduction of this species, so it is sporadic, but the plants are hardy and long-lived.

Collinsia is a genus of about 20 species of annual flowering plants, consisting of the blue eyed Marys and the Chinese houses. It was traditionally placed in the snapdragon family Scrophulariaceae, but following recent research in molecular genetics, it has now been placed in a much enlarged family Plantaginaceae.

A decoction of the plant parts was made by the Navajo people for narcotic and other medicinal usage. In times of food shortage, the berries were used by Native Americans as a food source, and though small, they have a sweet taste. Pathogens. C. umbellata is the alternate host for the comandra blister rust (Cronartium comandrae), a rust fungus that affects pine species in North America. Comandra blister rust can cause tree losses of up to 7% in some regions where it is common. When C. umb is infected by the rust aeciospores from the pine host, yellow, blister-like spots bearing urediniospores appear on the leaves of the plant within 20 days. In the following weeks, teliospores develop on brown, hairlike telia that germinate to produce basidiospores, the fungal life stage capable of infecting pines.

Comarostaphylis diversifolia is a rare shrub in the heath family known by the common name Summer Holly. It is slow growing in an upright form up to a height of 20 feet or more, with striking white flowers in the spring, an incredible summer display of holly-like red berries , and attractive gray bark. It is native to southern California and northern Baja California, where it grows in coastal chaparral habitat, usually on well drained slopes. Its bark is gray and shreddy and the tough, evergreen leaves are oval in shape and sometimes toothed. The flower cluster is a raceme of urn-shaped flowers very similar to those of the related shrubs, the manzanitas. The fruit is a bright red, juicy drupe with a bumpy skin. There are two subspecies. C. d. ssp. diversifolia - native to the coastal hills of southern California and Baja California, C. d. ssp. planifolia - native to the Channel Islands of California and the Transverse Ranges north of Los Angeles. Subspecies diversifolia tends to grow with Mission Manzanita, Scrub Oak and Toyon.

In nature, Summer Holly is most often found on shady dry slopes, near occasional creeks or runoffs. It grows slowly until it breaks through the lower canopy, and gets its leaves in the sun. In landscapes it does best in dry part shade, near irrigated spots or other slightly damp areas. It prefers heavier, richer soils that retain the little moisture it gets a little longer. Best to plant Summer Holly in the fall, so it can get established by summer. This plant is among the least tolerant to direct water in the summer. After the first year, direct water in the summer will usually kill it.

Desert lavender (Condea emoryi) is a fast-growing, aromatic shrub prized for its silvery-white, lavender-scented foliage and vibrant purple flowers, which can bloom year-round. Its fuzzy leaves and stems add texture to gardens, and it forms a dense, upright bush that can reach up to 12 feet tall and 8 feet wide.

As a semi-deciduous plant, desert lavender may drop some of its leaves during the heat of summer. It thrives in full sun and well-drained soil, making it an excellent choice for low-maintenance, water-wise landscapes. While highly drought-tolerant, it can handle occasional summer watering, about once a month.

This versatile shrub can be pruned into a hedge, with pruning ideally done in summer or fall. desert lavender is deer-resistant and attracts pollinators, making its fragrant flowers a favorite for hummingbirds and bees.

Grows best in sandy, coarse-grained or other fast draining soil. Selection from the Mojave Desert made by Carol Bornstein and introduced by santa Barabara Botanic Garden.

Constancea is a monotypic genus of flowering plants in the aster family containing the single species Constancea nevinii (formerly Eriophyllum nevinii), which is known by the common name Nevin's woolly sunflower. It is endemic to three of the Channel Islands of California, where it grows in coastal scrub habitat. This is a small shrub or subshrub generally growing up to one or 1.5 meters tall, and taller when in erect form, with a branching, woolly stem. The whitish, woolly oval leaves may be up to 20 centimeters long and are divided into many narrow lobes with edges curled under. The flower cluster is a cluster of 10 to 50 or more small flower heads, each on a short peduncle. The flower head has a center of hairy, hairy, star-shaped yellow disc florets and a fringe of four to nine yellow ray florets each about 2 millimeters long. The fruit is an achene a few millimeters long with a small pappus at the tip.

Like many Channel Islands endemics, this plant was threatened with extinction by the herbivory of the feral goats living on the islands; the goats have since been removed and the plant is recovering. The yellow flowers contrast nicely with the silvery-gray foliage. This plant would be good for coastal gardens in southern California where temperatures are moderate and it would receive some fog drip.

Tolerates almost any soil type. Prefers sun in coastal sites, and part shade in inland sites. Introduced by C. Bornstein, santa Barbara Botanical Garden.
