Frangula (Rhamnus) purshiana
Native to moist places from Mendocino County northwards and throughout the Sierra Nevadas, this medium sized deciduous tree is distinctive for its shiny, green leaves with strong venation. Ranges in height from 15 to 30 ft. tall. Bees are attracted to the clusters of small, cream-colored flowers and birds enjoy the dark purple berries which follow. Plant in riparian zones or in areas where it can receive regular moisture. Give full sun to part shade. Requires protection from the afternoon sun in the hottest areas.
Fraxinus latifolia
Fast growing hardwood tree, native to stream and river banks or other wetland habitats from San Diego to British Columbia. Growing 30 - 70 ft. tall, this deciduous tree has medium green compound leaves. Male and female flowers occur on separate trees and are not particularly showy. They bloom just as the spring foliage is leafing out. Fruits occur on the female trees and are paddle-shaped, single samara-style fruits in drooping clusters. Birds and mammals eat its seed, but probably used more as a nesting site for birds. Plant in sun to light shade with regular to moderate water.

Because of the nature of their branching, ‘San Gabriel’ and ‘Pacific Sunset’ both espalier well. An excellent nectar plant for orioles. Requires full sun. No summer water once established. Needs decent drainage.
Galvezia (Gambelia) speciosa
Evergreen shrub native to the Channel Islands off the So. California coast. Forms an arching mound of medium green foliage 3-4 ft. tall x 5 ft. wide, but can climb or lean on other shrubs to grow even taller. Clusters of scarlet, tubular flowers decorate the branch tips in spring and intermittently throughout the year and are adored by hummingbirds. Full sun along the coast, light shade in hot areas. Drought tolerant and amenable to pruning. Hardy to around 20°F.
Gambelia (Galvezia) speciosa ‘Firecracker’
An interesting, evergreen subshrub from the California Channel Islands. Showy, deep-red, tubular flowers decorate the branch tips and are highly attractive to hummingbirds. The cultivar ‘Firecracker’ was selected by Tree of Life Nursery for its compact habit, growing 3 foot tall and 5 foot wide, with fuzzy, pale green leaves and larger, red, snapdragon-like flowers. A natural along the coast where it will grow in full sun to light shade, afternoon shade is best in hotter inland sites. Drought tolerant once established, but enjoys occasional summer water, especially away from the coast. Hardy to 15 -20 degrees F.
Garrya elliptica
Garryas are grown primarily for their winter flower catkins. The longer, pendulous male catkins have traditionally been the most sought after with selections like 'James Roof' and 'Evie'. Male and female flowers occur on separate plants and both must be present for the female to produce their lovely grapelike clusters of fruit. These plants are seed grown so males and females are of equal probability. All plants feature larger, evergreen leaves on multitrunked shrubs reaching 10 - 15 ft tall and wide. Very amenable to pruning. Plant in full sun or partial shade. Provide moderate irrigation inland, but established plants will be drought tolerant near the coast where they occur naturally. Somewhat deer resistant.
Garrya fremontii
Evergreen shrub with leathery leaves and handsome dangling catkins in late winter and early spring. The male and female flowers occur on separate plants. Native to the west coast where it grows in mixed evergreen forest and chaparral plant communities. This species is a good choice for summer-hot interior sites with well drained soils. Grows 8 - 10 ft. tall and wide in full sun to light shade and is drought tolerant once established. A good specimen shrub or candidate for hedgerow or screen where it provides cover and food for birds and small mammals. Somewhat deer resistant.
Gaultheria shallon
A handsome evergreen shrub, happiest in fog shrouded coastal zones. Large, leathery, dark green leaves are a gorgeous foil to the loose clusters of white to pinkish urn-shaped flowers. Fat, blue-black berries follow and are relished by wildlife and eaten by people too. Salal can grow tall in moist coastal areas of the Pacific Northwest but usually forms a ground cover 2 - 4 ft. tall and spreading in California. Best with some shade and acidic, humus-rich, moist soils. The foliage is prized for flower arranging. Deer resistant.
Hazardia squarrosa v. squarrosa
For a splash of color in late summer and fall, this goldenbush is a great choice, providing clusters of cheery, golden flowers at the height of the dry season, which supply food for butterflies. Birds enjoy the seeds which follow. Rounded leaves with sawtooth margins line the stems and emit a wonderfully sweet scent. This seed strain comes from a hot area in Big Sur and is remarkably compact and rounded, reaching about 3 ft. tall and wide. We’ve found it to be very adaptable, tolerant of clay soils and zero to occasional irrigation. Likes full sun but will accept a little shade. Plant with buckwheats, Salvias, and California fuchsias. Not usually available in Northern California nurseries.
Helenium bigelovii
Native to moist meadows of California and S. Oregon, this summer flowering perennial makes a lovely addition to the garden. The cheerful golden-yellow petals turn down slightly from the rounded dome-like center. The golden daisy-like blossoms are held above the rosette of smooth green leaves on 2 - 3 ft. tall stems and attract a wide variety of insects including bees and butterflies. Despite the common name this plant does not cause allergies. It was originally used for snuff, hence the name sneezeweed. Plant in full sun to light shade with regular water. The seed for this crop is from the Pitkin Marsh in Sonoma County.
Helenium puberulum
Summer brings clouds of yellow pom-poms which age to brown on this native member of the sunflower family. The round flower clusters sit atop rings of small, down-turned petals, held up on flat stems lined with lanceolate leaves. The flower stalks reach 3 to 5 ft. in height and can be cut down once blooming has finished. Plant in full sun to light shade. Rosilla grows naturally by creeks and seeps and enjoys regular moisture, but will tolerate some drier periods. Attracts a wide variety of insects including bees and butterflies. Goldfinches love the seed. Reseeds readily.
Helianthus californicus
This giant, perennial sunflower is native to riparian habitats in openings with decent light. Dormant in the winter, spring brings rapid growth, with narrow, bright green leaves on tall stalks rising 7 feet or more above a root system which spreads widely. Summer brings many small, golden-yellow sunflowers on the branch tips which are quite dramatic in full bloom. Flowers attract bees and butterflies and the seeds are relished by birds. Perfect for stabilizing soil where there is some summer water and plenty of space. Once established it can take it dryish, but will flower better with water. An excellent cut flower.
Heteromeles arbutifolia
Toyon is a handsome native evergreen shrub 6 - 10 ft. tall and wide. Sun to part shade, drought tolerant. Clusters of lacy white flowers bloom in summer and areattractive to pollinators. Spectacular bundles of red berries are relished by birds and are a great winter decoration. Valuable as a specimen, screen, hedge or bank plant.

This species comes from the San Jacinto and Santa Rosa mountains of southern California.
Heuchera maxima
Native to the Channel Islands, this is one of the most adaptable and vigorous of the alum roots, forming broad evergreen mounds of bright green folilage 1 - 1 1/2 ft. high. Maroon flower stems are 3 ft. high topped with pink blushed creamy flowers that have a slight green haze.
