Frangula (Rhamnus) californica ‘Eve Case’
This well-known cultivar of coffeeberry was introduced to the trade in 1975 by the Saratoga Horticultural Foundation. Coffeeberry is a handsome evergreen shrub with broad leathery leaves. This selection grows to 6 ft. tall and wide, though mature specimens can reach 8 ft. or more tall under ideal circumstances. The small yellow-green flowers are not showy but attract an array of pollinators. The berries start out green and age to burgundy-black and are attractive to small mammals and birds. A larval food source for pale swallowtail butterfly. Adaptable, grows in sun to light shade. Drought tolerant but appreciates occasional summer water.
Frangula (Rhamnus) californica ‘Gumdrop’
This somewhat diminutive selection of our native coffeeberry was discovered as a seedling from a plant found on Montara Mountain, south of San Francisco. We thought the dense form and evocative, gumdrop shape was deserving of this sweet moniker. Only reaches to about 5 - 6 ft. tall and wide and offers attractive, slightly-concave, dark green, leathery leaves, not unlike its close relation ‘Leatherleaf’. Will accept full sun in somewhat cooler locations but enjoys a little shade in hotter regions. Occasional to infrequent irrigation once established. The small, yellowish flowers which appear in spring and summer are extremely popular with bees, and the juicy, purple fruits which follow are enjoyed by birds.
Frangula (Rhamnus) californica ‘Leatherleaf’
Another fine Roger Raiche selection, this coffeeberry cultivar is well worth growing. The evergreen leaves are particularly dark and broad with a mounding habit growing 5 - 6 ft. tall and wide. The tiny flowers attract a wide array of pollinators. Larval food source for pale swallowtail butterfly. The handsome fruits go green to red to black and are enjoyed by small mammals and birds. Plant in sun to light shade. Drought tolerant once established though occasional summer watering is helpful. An adaptable and useful shrub for both formal and naturalistic plantings.
Frangula (Rhamnus) californica ‘Mound San Bruno’
Selected by Roger Raiche on San Bruno Mountain in San Mateo County, this is one of the most reliable coffeeberries. Grows 6 ft tall and wide, with narrow, evergreen leaves and a compact habit. For full sun on the coast to part shade inland. Will tolerate irrigation, but needs only occasional summer water once established. Flowers are loved by pollinators, especially bees. A larval food source for the pale swallowtail butterfly. Provides black juicy fruit in the fall for thrushes, jays, mockingbirds, and robins. May grow to as much as 8 ft. tall with moderate water and good drainage in cooler areas.
Frangula (Rhamnus) californica ‘Olema’
We discovered this large, dense form of our native coffeeberry near the town of Olema in coastal Marin County. While it reached up to around 15 ft. tall and wide in nature, it has been a little slow to do so in the ground here at the nursery. After about 4 years, it’s reached a height of about 9 ft. This selection of coffeeberry is ideal for a tall hedge or screen where an evergreen shrub is needed to create privacy. Grows well in full sun somewhat near the coast but will need a little shade in hot, inland sites. Occasional to infrequent irrigation once established. Coffeeberries are some of the best habitat plants. The small, yellowish flowers are adored by bees in spring and summer, while the plump, purple fruits that follow are relished by birds.
Frangula (Rhamnus) californica ‘Seaview’
This highly sought after selection of our native coffeeberry stays low and compact only reaching 2 – 3 ft tall and up to 6 ft wide. The tidy, deep green leaves form dense rosettes with small cream-colored flowers appearing from spring through summer. Deep purple “berries” form dense clusters in the summer and fall. Enjoys full sun to moderate shade and moderate to occasional water once established. An excellent habitat plant for bees and birds.

Frangula (Rhamnus) californica ssp. tomentella
This distinctive species of coffeeberry features blue-grey leaves with velvety, silver undersides and grey, fuzzy stems. The somewhat open form grows 6 to 10 ft tall and wide. Clusters of small cream-colored flowers appear from winter through spring and are a favorite of bees. The deep purple fruits which follow are highly prized by birds. While native to serpentine soils, this coffeeberry should thrive anywhere with decent drainage. Provide full sun to light shade and give occasional irrigation once established. The grey stems contrast beautifully with the shiny, dark green leaves of Ceanothus ‘Yankee Point’.
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.
Fremontodendron ‘California Glory’

Grindelia stricta var. platyphylla ‘Mendocino’
This selection features particularly large bright yellow 2 1/2 inch daisies over a long period in the summer. Each fat green flower bud holds a dollop of gummy white resin which protects the blooms from predators, hence the name “gum plant”. 'Mendocino' is a particularly prostrate form under 8 inches tall and spreading to at least 6' wide. Native to dunes, marshes and bluffs in coastal scrub throughout coastal California. Excellent pollinator plant. Useful in a meadow planting or with other low groundcovers and shrubs. Looks nice draping over a wall too. An adaptable plant for sun to light shade, moderate to occasional water. A natural along the coast where it tolerates wind and salt spray. 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 autumnale
This desirable autumn bloomer is known for its masses of bright yellow daisies up to three inches wide, perched atop stems two to three feet high. Lance-shaped leaves of light green create dense mats six inches high. Native to Northern California and much of North America where it grows in moist meadows. Will slowly increase to form small colonies. Plant in full to part sun and provide regular water. Attracts bees and butterflies. Deer resistant.

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.
Helianthella californica
Native perennial sunflower growing in chaparral and woodland communities throughout much of California. Forms clumps of dark green, lance shaped leaves under a foot tall.

A fast growing annual with coarse heart-shaped leaves and topped with an abundance of 3 inch flowers, with bright yellow petals and brown centers on branched stalks. An excellent habitat plant, providing nectar and pollen for a wide array of bees and butterflies as well as seed relished by birds. A highly variable species with a long history of uses and domestication. Plant in full sun where it is adaptable to soil types and watering regimes. Can manage in dryish conditions but best with moderate water, especially early in its growth.
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.
