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 dipetala
This is our only native ash with showy flowers. A large shrub or multi-trunked tree native to slopes, canyons and stream banks in hot interior regions of the state. Grows 7 to 25 ft. tall with pinnately compound leaves. The creamy white flowers are produced on dangling racemes in mid to late spring, followed by pendulous clusters of samara fruits. Like the California buckeye, it loses its leaves early to evade the long dry summer. Grows in sun to partial shade. Drought tolerant once established.
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.
Hastingsia alba
This hard-to-find native bulb features elegant, branched stalks, 3 ft or more high, supporting racemes of sparkling white flowers. The dense blossoms display narrow petals and protruding stamens, giving them a delicate and soft appearance. Grey-green, strap-like leaves grow radially from base of the stalk, creating a tidy rosette 12" - 18" wide. Grows happily in most soils in full sun with regular water, where the bulbs may multiply. In part shade, this lily relative will be a little more drought tolerant. Plants emerge in late winter and go dormant by the end of summer. Hails from the mountains of Northern California, where it makes its home in meadows and open woodlands.
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.
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. Blooms April through June with small, golden-yellow sunflower heads which rise above foliage 18 inches to 2 ft. tall. Plant in full sun to light shade where it will be quite drought tolerant once established. The flowers attract a wide array of pollinators and beneficial insects.
Heracleum maximum
Big, bold, native perennial 3 - 8 ft. tall, is striking in mass or as a specimen. Forms a rosette of large lobed leaves followed by stout flower stems carrying large umbels of white flowers. Thrives in rich soils with some moisture. Full sun along coast, part shade inland. As a member of the carrot family (Apiaceae) the flowers are very effective at attracting beneficial insects. Larval food source for anise swallowtail butterfly. Formerly known as Heracleum lanatum.

This species attracts hummingbirds.
Heuchera rubescens
The pink alumroot stands out with bell-like flowers of pink and white held in clusters on slender stems up to 1 ft tall. The round, scalloped leaves form low, dense mats up to 1 1/2 ft wide and about 6 inches high. This western mountain dweller looks beautiful in a rock garden but will do well in any situation with part shade and good drainage. Needs moderate to occasional irrigation once established. Attracts hummingbirds. Great in a container.
Holodiscus discolor
An elegant, deciduous, native shrub growing 5 - 6 ft. tall or more, depending on the site, and at least as wide. Beautiful, cascading clusters of creamy white flowers hang from branch tips in early summer. The fragrant flowers attract pollinators and a number of butterflies use it as a host plant. Best with light shade. Drought tolerant, but will accept some moisture.
Iris chrysophylla
Native to far northern California and into western Oregon, this uncommon iris grows in fast draining soils in open forests and woodlands. A small scale iris, usually under 12 inches tall in bloom, spreads slowly from slender rhizomes. The delicate blossoms flower in the spring and can vary in color from white to cream to yellow, with a central yellow splash and prominent dark venation. Grow in sun to light shade with occasional to little watering. Visited by bees and hummingbirds. Deer resistant.
Iris macrosiphon
A widespread and variable species growing throughout Northern California’s coast ranges and Sierra Nevada foothills. Our crop is grown from seed collected in western Sonoma County which has lovely lavender-blue blossoms April through May. Forms small clumps of narrow and slightly arching blades under 18 inches tall. Often found on wooded slopes, in openings or edges of forests where it will form small patches. Prefers good drainage, drought tolerant, or just a little summer moisture. Deer resistant.
Koeleria macrantha
An evergreen perennial bunchgrass forming a rounded tuft of narrow, bluish-green blades 6 - 12 inches long. Spike-like panicles of pale green florets rise another 6 - 12 inches above the blades in summer. This widespread species grows from coastal woodlands and prairies to high mountains. Best in sunny locations with well drained soil and moderate to a little summer water. Tolerates light shade, does NOT like heavy, wet soils or deep shade. Deer resistant.
Lewisia cotyledon
Named for Meriwether Lewis, this attractive succulent is native to higher elevations in Northern California and Southern Oregon, typically granite outcrops. The flowers which usually emerge in spring and summer, can range in color from yellow to orange to pink to red. These frost hardy plants form evergreen rosettes, approx. 8 - 10” tall by a foot or so wide. Lewisias need very good, sharp drainage, are heavy feeders, and love a granite rock mulch. They like to be grown sideways, in rock walls, where their crown can drain any moisture away. Plant somewhat high in a fast draining mix and feed every now and then. Morning sun, afternoon shade is best inland. Water as you would any succulent, sparingly, and keep the crown high and dry.
Lilium pardalinum
An elegant and beautiful native from moist places and along stream banks in many plant communities from southern Oregon to southern California. A reliable species easily growing 4 ft. tall or more, slowly increasing its width over time. The Turk’s cap style flowers bloom in summer and are orange with red tips and maroon spots. Dies back to the ground in winter. Prefers fertile, well drained soils. Where summers are cool you can plant in full sun. Elsewhere plant in filtered sun, light shade or afternoon shade. Requires moderate summer water.
Linum lewisii
A profusion of sky-blue, five petaled, shallowly cupped blossoms flower in late spring and into summer. Growing 12 to 18 inches tall with slender stems and narrow leaves. Can be short lived but often reseeds. A lovely filler, whose true blue flower color seems to go with everything, and the fine foliage contrasts nicely with a variety of leaf colors and shapes. Plant in full sun with moderate to infrequent summer water. Deer resistant.
Lomatium dissectum
This carrot relative features clusters of small burgundy or yellow flowers held in round clusters in open umbels. Tall, slender stalks about 3 - 4 ft high support the blossoms above broad, finely dissected leaves. Pollinators love the flowers and the anise and indra swallowtail butterflies depend on the leaves as a food source for the developing caterpillars. Grows throughout much of California in hot, inland areas. Plant in full sun to light shade and provide little to no water once established. Needs excellent drainage. A rarity in nurseries.
Lonicera ciliosa
Native to north slopes, creeks and river banks from very northern California to British Columbia and Montana. Lovely blue-green, oval-shaped leaves on rapidly growing woody stems will clamber up any support it can find. Terminal flower clusters with narrow, trumpet-shaped, orange flowers are adored by hummingbirds. Red translucent fruits follow that are relished by birds. Plant in cool sun to moderate shade with regular water. Possibly deer resistant.
Lonicera involucrata
