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.
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.
Arabis blepharophylla
A charming spring blooming perennial, native to rocky places of coastal scrub, Santa Cruz to Sonoma counties. The neat foliage grows in tight low rosettes and are topped with vibrant rose-purple mustard-like flowers 8 to 10 inches tall. A natural for coastal areas, it requires some relief from the hot sun and additional water inland. Perfect with other non rampant plants of similar requirements on a slope, rock garden, or along a border. Excellent container plant. Good nectar source for butterflies.
Arbutus menziesii
A beautiful native evergreen tree which features handsome, smooth, reddish bark that peels in thin flakes. Leaves are leathery and shiny dark green. Large clusters of white flowers give way to red-orange berries that can remain into winter if the birds don't get them. It can be tricky to establish, necessitating planting in the fall. MUST have good drainage and just enough water to establish. Once established give only infrequent deep waterings or no water at all. Bees and hummingbirds love the flowers.
Arctostaphylos ‘Emerald Carpet’
This popular manzanita forms a wonderful, dense, green groundcover around 1 ft. tall by 6 ft. wide. Clusters of small, white, urn-shaped flowers decorate the plant in early winter. A natural hybrid discovered on Haven's Neck on the southern Mendocino Coast. Often planted en mass to create a large scale groundcover. Somewhat slower growing than bearberry and slightly taller over time. Enjoys full sun near the coast but does best in hotter areas with some afternoon shade. Needs moderate water once established.
Arctostaphylos ‘Howard McMinn’
One of the most popular of the manzanitas, for several good reasons. It is rounded in form and profusely branched, growing 5 - 7 ft. tall. It has shiny green leaves and abundant light pink flowers. Beautiful mahogany trunks create a wonderful sculptural effect. The dense foliage responds exceptionally well to pruning - even shearing, and tolerates a far greater range of soils and watering regimes than most manzanitas.
Arctostaphylos ‘Pacific Mist’
A broadly spreading shrub, fast growing for a manzanita, eventually forming a good dense ground cover 1.5 - 2.5 ft. tall by 10 ft. wide. Handsome gray-green leaves with deep reddish-brown bark. Small clusters of white urn-shaped flowers in late winter are pretty, but it is not a heavy bloomer. This fine introduction from Rancho Santa Ana Botanic Garden is proving to be dependable and disease resistant. Plant in sun or light shade. More drought tolerant than the popular bearberries. In cool summer areas may need no additional summer water once established. In hotter inland sites,occasional deep summer waterings is best. It is believed to be a cross involving the rare Bonny Doon manzanita.
Arctostaphylos ‘White Lanterns’
This lovely manzanita believed to be a selection of A. densiflora originated at the Santa Barbara Botanical Gardens many years ago, but today it is a rare find in nurseries. Slowly growing to a dense mound 3-5 feet tall and wide, this tough and disease resistant plant is equally at home as a beautiful specimen or massed in large plantings. Especially heavy blooming, this shrub is covered with clusters of white blossoms opening from pink buds over a long period in late winter. Excellent early nectar source for hummingbirds and bees. Plant in full sun to very light shade with little to no water once established.
Arctostaphylos cruzensis
This rare, low-growing manzanita comes from the San Luis Obispo coast. Features grey-green, wedge-shaped leaves and soft pink flowers in the winter. Its distinctive creeping habit makes it ideal for crawling over walls or lining walkways. Provide full sun to light shade and moderate to infrequent irrigation once established. Good in containers.
Arctostaphylos densiflora
One of California's rarest natives, this is the pure, true species. Exists only in a very small preserve in western Sonoma Co.. Distinctive for the profusion of beautiful pink to white urn-shaped blossoms they produce in winter and small, shiny bright green leaves. Variable in height but typically grows 3 ft. tall by 6 ft. wide. Does best in its native Sebastopol sandy soils with full sun to light shade and occasional to no summer irrigation.
Arctostaphylos edmundsii ‘Bert Johnson’
Choice, low growing manzanita introduced by the Tilden Botanic Garden. Dense, mounding or cascading habit growing to around a foot tall by 6 ft. wide with small dark green leaves and bronzy new growth. Not as fast growing as 'Carmel Sur'. Clusters of tiny pink to white urn-shaped flowers in winter attract hummingbirds and are followed by handsome cinnamon colored little apple-shaped fruits. Excellent cascading over walls, rocks, or containers in sun to light shade. This manzanita has proven adaptable and fairly garden tolerant putting up with heavy soils and more summer water than many. Full sun along the coast with light shade in hot inland sites. Drought tolerant once established but appreciates occasional summer water.
Arctostaphylos edmundsii ‘Carmel Sur’
Perhaps the fastest growing variety of this species. Attractive gray-green foliage with a dense, spreading habit under 1 ft. tall and 6 ft. across. Light pink flowers appear in winter but are few and infrequent. A handsome alternative to other groundcover manzanitas. More drought and heat tolerant than the bearberries and 'Emerald Carpet'. Likes full sun but may enjoy a little afternoon shade in especially hot inland sites.
