Agoseris grandiflora
With a wide distribution throughout the state, the California dandelion is much more refined and well-behaved than its European, weedy look-alike. Found in oak woodland, chaparral, and many other plant communities in part-shade or bright dappled light. Slender, dissected, low, fuzzy gray-green leaves give rise to stem-like peduncles up to 2+ feet tall that are topped with rounded, flat, gold-yellow flower clusters from March-May, followed by large, perfectly rounded white globes of seeds that are wind-dispersed. Plant in part-sun or in areas with bright dappled light that drain well and are summer dry. Does not reseed aggressively like the European dandelion. Drought-tolerant.
Agrostis pallens
A fine textured, drought tolerant, spreading, perennial grass that forms an undulating, naturalistic, meadow look, or can be mowed and used as a lawn substitute. Native to meadows, open woodlands and forests in many plant communities in California north to British Columbia. Grows 1 -2 ft. tall with airy flower stems in late spring to early summer. May be shy to flower in shady areas. Plant in sun to light shade, with decent drainage, where it will accept both water and drought. Will go dormant in summer without irrigation. If using as a lawn substitute, it will need summer irrigation, though requiring far less than a traditional lawn. Excellent understory among trees or shrubs, for rain gardens, bio-swales, meadows or mowed as a lawn substitute. Host plant for a number of butterflies. Deer resistant.
Agrostis scabra
Native to middle and high elevation forests and meadows throughout California, this small bunchgrass forms dense tufts of blue-green foliage about six inches high with airy inflorescences rising another eighteen inches. Works well in a meadow planting or in a container. Combine with other small perennials such as Grindelia and yarrow or plant in large masses to show off the delicate grass flowers. Needs regular moisture and full sun to light shade. Deer resistant.
Allium amplectens ‘Graceful Beauty’
This western native onion grows in sunny openings in forests and woodlands, often on serpentine. Narrow, fragrant leaves make way for globe shaped flower heads on sturdy stems 12 - 16 inches tall. The flower heads which emerge in late spring and early summer are made up of many starry, white florets with elegant lavender anthers and pale pink veins. Papery bracts persist after blossoms fade, adding interest. If happy can reseed readily. Attractive to bees and butterflies. Very drought tolerant. Reported to be gopher resistant, but may need further analysis. Deer resistant.
Allium falcifolium
This is one of our favorite native bulbs and it is rarely available in nurseries. In spring or summer, dense, rounded clusters of flowers, ranging in color from light to deep pink, sit atop thick, flattened stems up to 10 inches high. The strap-like leaves are few and don't distract from the chunky blooms. Needs excellent drainage and a lean, rocky soil. Once the flowers are done, allow the plant to go dormant with no irrigation. Native to rocky, sunny outcrops from Santa Cruz up to southwestern Oregon. Nestle among rocks and little succulents to show this unusual onion off to your friends. Works well in a container where its somewhat tricky requirements can be more easily met.
Allium unifolium
An adaptable and easy to grow native onion with handsome blue-green foliage. Late spring brings beautiful lavender-pink flowers on short stems 6 - 8 inches tall. Native in the Coast Range from the Central Coast, northwards. The flowers on this form have a particularly appealing saturated color. The original plants were given to us by the internationally known bulb expert and native plant horticulturist, Wayne Roderick. Fairly water tolerant, often found on seasonally moist and heavy soils. Spreads vigorously by seeds or bulb offsets. Goes dormant after bloom and will tolerate dry conditions at that time. Attractive to bees and butterflies. Reported to be gopher resistant. Deer resistant.
Alnus rhombifolia
From creeks and rivers throughout California, the white alder rapidly grows to become a large tree, reaching to 50 ft. or more at maturity. Serrated green leaves produce an excellent canopy above the straight, silvery-gray trunk. In winter, when the leaves have fallen, the ghostly branches make a striking silhouette with dangling catkins from the branch tips. An excellent plant for creek restoration where its aggressive roots help to stabilize banks. Keep away from irrigation pipes and foundations. Needs regular moisture and sun to light shade.
Ambrosia chamissonis
The silvery mats of this sand-dwelling species are important for soil stabilization along our coastline, but can also be used as an attractive, evergreen groundcover in the garden setting. Dissected leaves line crawling branches, forming a dense carpet up to about 10” high and spreading wherever they have room to grow. While vigorous, it can be pruned back easily. In summer, short stalks of inconspicuous, cream colored flowers raise, followed by bur-like seed capsules. Plant in sunny locations with moderate to occasional irrigation. Tolerant of different soil types.
Amelanchier alnifolia
A common native shrub or small multi-trunked tree often found growing along seasonal streams. Serviceberries provide a touch of autumn color where the leaves turn a lovely butterscotch yellow. The white spring flowers are followed by dark blue-purple fruits coveted by ring neck doves in the wild. Sun to partial shade. Moderate to infrequent water. Many butterflies use this species as a larval host, such as the California hairstreak and the Ceanothus silkmoth. Grows well in a large container.
Amorpha californica var. napensis
A lovely and rare native shrub of the pea family, occasionally seen in woodland and chaparral communities in the coast ranges around the San Francisco Bay Area. Offering a delicate, airy quality, this deciduous shrub grows to around 6 ft. tall and wide, though can get bigger in the wild. Intricate flowers are closely set on slender spikes and are made up of tiny, intense indigo-purple petals with protruding bright orange stamens, charming on close inspection. This rare and threatened shrub is the larval food source for the California dogface butterfly, our state insect! Bees and butterflies nectar on the flowers as well. Best in lightly shaded areas with occasional to no summer water needed once established. Deer resistant.
Amsinckia menziesii
A bright, yellow-orange ANNUAL with curled clusters of little trumpet-shaped flowers resembling the scrolled head of a violin. Flower stalks of one-to-three feet tall gradually unfurl with new blooms from mid-spring to early summer. The warmly-colored blossoms are a great nectar source for butterflies and develop into seeds adored by goldfinches and other songbirds. This grassland native adapts to the garden setting, where it prefers full sun and occasional irrigation. Will self-sow.
Anaphalis margaritacea
An adaptable plant with silver-green leaves that are densely white and woolly beneath. The flowers appear in summer and are made up of pearly white papery bracts surrounding yellow centers. The “straw flowers” retain their shape and color and are often used in dried arrangements. Tolerant of almost any soil type, it prefers full sun where it will grow in moist to somewhat dry conditions. Can spread vigorously, perhaps best used in meadow plantings or other naturalistic settings. Grows 1 - 3 ft. tall and spreading. Dies back to the ground in the winter. Larval food source for the painted lady and American lady butterflies. Deer resistant.
Anemone deltoidea
Rhizomatous perennial native to coniferous forests in the coastal mountains of Northern California through Washington. Forming low colonies, 6 inches or so tall with slender stems holding three leaflets. Simple, pure white flowers with a central shaft of anthers hold themselves just above the foliage. Spreads vigorously and best used with shrubs, ferns or other sturdy subjects. Can romp over smaller perennials. Sweet addition to the woodland garden where it will grow in full to part shade with regular to a occasional summer watering. Good in containers too. Dies back to the ground in winter.
Anemopsis californica
An unusual plant - native to wet areas, but adaptable to regular or moderate garden water. The low rosettes of leaves spread into attractive colonies. The white flowers, or actually, flower bracts, are very showy in late spring. Sun to light shade with moisture. Herbalists use roots and leaves for a topical antibiotic and other uses.
Angelica arguta
A remarkable form of this native mountain Angelica with striking bluish-gray foliage. Umbrella-shaped clusters of white flowers sit on stalks up to 6 feet in height. Needs moderate irrigation and dappled shade inland. Combine with native Heleniums, lilies and columbines to create a beautiful woodland flower patch. Great for native pollinators. A larval food source for the anise swallowtail butterfly.
Angelica breweri
From the Sierras and the Klamath mountains comes this elegant member of the carrot family. Clear white flowers perch like little stars in flat-topped clusters up to 10 inches wide. Flower stalks can reach 6 feet in height with green serrated leaves forming 2 foot tall mounds at the base. Enjoys dappled shade away from the coast and moderate water. Great for native bees and butterflies. A larval food source for the anise swallowtail butterfly.
Angelica californica
Striking stalks up to 6 or more feet tall hold flat topped clusters of white flowers above low growing emerald-green leaves. This uncommon member of the carrot family needs only occasional water once established. Naturally occurs under the dappled shade of oaks where it cohabitates with ferns, hound's tongue, yerba buena and woodland strawberries. Excellent for attracting beneficial insects and is a larval food source for the anise swallowtail butterfly. May go summer dormant when allowed to dry out.
Angelica capitellata
We are excited to offer this denizen of mountain meadows and forests known for its clusters of white flowers or “buttons” on tall stalks reaching up to 5 feet in height. Lance-shaped leaves of bright green form upright mounds at the base of the stalks. Ranger buttons are easily identified by the hairy stems within the inflorescences. Provide regular water and dappled shade. This unusual member of the carrot family combines beautifully with ferns, lilies and other forest dwellers.
Angelica hendersonii
Found in nature on the immediate coast, though well adapted to the watered inland garden. It has the overall look of a stout cow parsnip with creamy white flowers in umbels and pinnately compound leaves of a deep green. Like many umbels, it is a good nectar source for beneficial insects. 4 - 6 ft. tall. Full sun to light shade. Good drainage with moderate summer water.
Angelica lucida
Large white flower clusters up to one foot across are held on stalks up to 5 feet tall above coarsely dissected leaves. Greener leaves and a more refined character distinguish this species from the more common Angelica hendersonii. While it is rare on the sea cliffs of northern California, sea-watch has a large distribution along coasts throughout the northern hemisphere. Give regular moisture and part shade in areas away from the coast. Attracts bees and butterflies.
Angelica tomentosa
This species offers striking, flat-topped clusters of white flowers held up dramatically on stalks reaching up to around 5 ft. tall. Handsome, pinnately compound, gray-green leaves mass at their base. A generally inland angelica found in more or less moist, lightly shaded places, usually on serpentine. It can grow in full sun as long as it has plenty of moisture during the growing season. An important plant for the Pomo for its many medicinal and shamanistic uses. Diverse pollinators utilize the flowers, while the anise swallowtail butterfly uses the stems and leaves as a host plant for the catterpillars. Enjoys moderate water in the garden with a late summer rest (low water).
Anisocarpus (Madia) madioides
A quiet perennial, native to woods and coniferous forests of California from sea level to 4000 ft. Dark green, narrow leaves are covered with soft hairs and form a sturdy, low, perennial clump. The bright yellow daisies top 8-10 inch flower stems over a long period, from late spring into summer. Able to thrive in dry shady conditions.May seed about in a friendly way.
Antennaria rosea
A charming, native, mountain dweller which grows among rocks and onto boulders at meadow edges. Forms low mats only a couple of inches high of woolly, gray leaves that creep and cascade. Short flower stems with small, creamy-white and rosy-pink papery bracts, bloom summer into fall. Plant in full sun to very light shade with good drainage and a little summer water. Good addition for the pollinator garden and is the larval food source for a number of butterflies including the American lady. This is one of the few natives which is so low growing you can plant it between stepping stones.
Apocynum cannabinum
Native throughout much of North America, California and our own Santa Rosa Valley. Grows 3 ft. tall and spreads vigorously by roots to form large patches. Small white flowers in summer. Turns beautiful shades of yellow in the autumn then dies back to the ground in the winter. Good for wild meadow or ethnobotanical garden. Important to Native Americans who used the stems for cordage, rope, twine nets etc. Sun to light shade with some moisture. Will tolerate dry conditions after blooming. Very attractive to butterflies. BEWARE! SPREADS VIGOROUSLY!
Aquilegia eximia
Large, orangey-red flowers with yellow stamens adorn this beautiful and uncommon native columbine. The pendant, brightly colored blossoms are larger than those of the western columbine but just as attractive to hummingbirds. Forms a 1 ft. high mound of foliage with flowering stalks reaching up to 5 ft. tall. Native to the Coast Ranges from Mendocino to Ventura Counties often on serpentine soils. Provide full sun to part shade and only water enough to prevent the soil from drying out completely. In areas far away from the coast provide a little shade from the hot afternoon sun. This species is a little more drought tolerant than the more common Western columbine.
Aquilegia formosa
A popular native perennial with fern-like foliage and wonderful, nodding, spurred blossoms of red and yellow. Best with a little shade and moderate to regular moisture, but will tolerate full sun in somewhat cooler climates. The flower stalks reach 1 1/2’ to 3’ tall, with the grey-green foliage forming a mound of about 1 ft tall and wide. Flowers attract hummingbirds, while the seeds are relished by small birds such as sparrows and Juncos. If seed pods are left on the plants, you may get volunteer seedlings in the fall.
Aquilegia pubescens
Found on open, rocky slopes in the southern Sierra Nevadas in sub-alpine and alpine plant communities. Low rosettes of divided, blue-green foliage, sprout from a taproot. Flower stems rise 10 - 20 inches above the fragrant foliage and carry upward facing, nectar rich, long spurred flowers, perfectly positioned for pollinating hawk moths, hummingbirds and butterflies. The flower color is variable and runs the gamut from cream to yellow to pink, often in delicate hues rather than solid colors, except for an occasional pure white. Hybridizes freely with the native red columbine, which invites various shades of red to the flower color possibilities. Grows well in low elevation gardens, given light shade and summer water.
