Pinus muricata
The Bishop pine is native to the northern California coast from Marin to Mendocino. A medium to large sized tree with a beautifully rounded crown and long, gray-green needles. Distinguished from the more southerly Monterey pine by its smaller cones which prick the hand when held. The Bishop pine often cohabitates with redwoods and other coastal conifers. Drought tolerant once established except in interior locations where an occasional deep watering may be required. Generally reaches 40 to 70 feet in height. Deer resistant.
Pinus ponderosa
Often associated with the Sierra Nevada mountains, this majestic pine can be found in Sonoma County as well. Long, gray-green needles form bushy clusters at the ends of branches with cantaloupe-sized cones that emerge at the very tips. The bark at maturity is a colorful patchwork of orange-tan plates separated by deep grooves of dark brown. It can grow a couple of feet a year, and averages from 60 to more than 100 feet in height in a garden setting. Provide full sun to light shade with occasional deep waterings when young. Needs decent drainage. Deer resistant.
Pinus sabiniana
A distinctive pine native to chaparral areas of California’s foothills. Sometimes called ghost pine due to its long gray needles set against dark, furrowed bark. While fairly slow growing, the gray pine can reach a height of 80 ft or more in well-draining sites with ample sunlight. Native Americans prized the big, prickly cones for their large, edible seeds. Prefers full sun and requires minimal water once established
Platanus racemosa
This most Californian of trees from the southern and central parts of our state features stunning bark mottled white and grey on a large, sculptured trunk. The maple-like leaves create an open canopy on this stately tree which can reach up to around 80 ft. tall at maturity. Seeds are produced in fuzzy pom-poms dangling on short stems and are a great food source for birds. In autumn, the leaves can turn orangey-yellow before they drop, adding rare fall color to the California landscape. Makes its home in sunny, low-lying areas and canyons with moderate to occasional irrigation. A great shade tree for the large garden and a larval host for the Western tiger swallowtail butterfly. Deer resistant.
Polypodium glycyrrhiza
Native to moist coastal forests from Monterey County to Alaska. This epiphytic fern enjoys shady environments where it grows on trees, logs and stumps, mossy rocks and slopes. The long, narrow, deeply lobed fronds spread by creeping rhizomes, which have a sweet licorice flavor and a history of use by various native American peoples. They grow happily in moist shady gardens, going summer dormant once conditions get too dry, returning with the autumn rains and coolness. Drought tolerant in somewhat coastal conditions. Good container subject. Deer resistant.
Polystichum munitum
The versatile western sword fern is an evergreen native fern from California to Alaska. In most gardens it will reach about three feet tall and wide. In prime areas near the coast where moisture is readily available and cool temperatures prevail, this fern can get up to 5 feet tall and wide. Excellent for shady beds, along walls, as a large scale groundcover and mixed woodland planting. Best with humusy soil and regular to moderate water, but drought tolerant once established and tolerant of most soil types. Actually quite adaptable and deer resistant.
Potentilla gracilis
Prolific displays of bright yellow flowers resembling buttercups make this little cinquefoil a hit from spring through autumn. Flowers are held on two foot stems above low mats of dissected,dark green leaves. Native to mountainous areas throughout California. Provide full sun to light shade and give occasional to regular moisture. Will spread slowly by seed if exposed soil is nearby. A favorite of bees and butterflies. Deer resistant.
Prunus ilicifolia ssp. ilicifolia
Hollyleaf cherry is a large, evergreen shrub that can grow more than 15 feet tall and wide, but is easily pruned to be more compact. This adaptable foothill native can be clipped into a formal hedge, pruned to be treelike, or left to its own natural gumdrop-shaped habit. Often it is used for background or screen plantings. Glossy, holly-like leaves are accompanied by showy displays of creamy-white flowers in narrow spikes from late spring to early summer. Plant in full sun to very light shade. Looks best with occasional deep waterings, but can tolerate very dry conditions once established. Although it requires good drainage, it is tolerant of heat, drought, wind and oak root fungus. An excellent habitat plant, offering food and cover for wildlife. Birds enjoy the small reddish-purple cherries. Generally deer resistant.
Rhamnus crocea
An under-used evergreen shrub native to chaparral, woodland, and coastal-sage scrub communities in California. Spiny redberry can grow up to 6 feet tall and wider, but is typically in the 2 - 4 ft. height range, spreading to 6 ft. or more across. Small, leathery, dark-green ovate leaves give this tough shrub a delicate look once established. The flowers on both male and female plants are inconspicuous, blooming from late winter into early spring. Female plants produce sporadic, jelly-like red berries. Great for dappled light under oaks, or a dry, shady woodland slope with California fescue. Can tolerate more sun near the coast, but prefers afternoon shade inland. Drought-tolerant once established. Larval host for a multitude of butterflies and moths, including the pale tiger swallowtail butterfly, Ceanothus silk moth, and Hermes copper butterfly. Deer resistant.
Rhamnus ilicifolia
A handsome evergreen shrub with small, dark green, leathery, serrated leaves. Found in the foothills and mountains of southern and central California, the Sierras and west of the Sacramento Valley up to 3,500 feet. Slow-growing, reaching 6-10 feet tall and wide, with a somewhat open, upright habit. Male and female plants are separate, producing inconspicuous yellow-cream flowers from spring into early summer. Female plants produce sporadic, gelatinous red fruits. Hollyleaf redberry can be planted in full sun to shade, but prefers a bit of relief from the afternoon sun in inland sites. It requires decent drainage and is drought-tolerant once established. Larval host for the pale swallowtail butterfly. Reportedly deer resistant.

Host plant to several butterfly species as well as the white-lined sphinx moth. Best with light shade and a little irrigation, though once established it is completely drought tolerant.
Ribes speciosum
One of California’s showiest gooseberry, blooming in late winter - early spring with charming bright red, pendant, fuchsia-like flowers. The thorny branches are arching and grow 4 - 6 ft. tall and wide. Best with light shade and needs no irrigation once established.
