Acmispon (Lotus) glaber (scoparius)
Bees go nuts over the bright-yellow flowers of this California native. From spring and into summer you can find this plant covered in blooms at the edges of chaparral throughout much of California.

Plant in full sun to light shade. Needs good drainage and no summer water once established. A remarkable number of butterflies use this species as a larval host plant, including the bramble hairstreak, orange sulphur, funeral duskywing, silvery blue, acmon blue and the avalon hairstreak.
Adelinia (Cynoglossum) grandis
From woodlands throughout Northern and Central California comes this alluring bluebells relative. Dainty flower clusters ranging in color from periwinkle blue to lavender appear on slender stalks in the spring. The leaves are what gives this plant its name: grey-green and tongue-shaped, emerging in the winter from basal roots. Plant in bright shade and don’t water once established. Needs decent drainage. Once this plant goes to seed it will go dormant, re-emerging in late winter. A great accent plant for under the dry shade of deciduous oaks.

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.
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.
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 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.
Arctostaphylos glandulosa f. repens ‘Mount Vision’
Found only in the Bishop pine forest of the Point Reyes Peninsula, the repens form has a low and mounding habit. This particular selection was picked for its exceptionally compact and creeping nature and large, gray-green leaves. Clusters of white flowers hang from branch tips in early winter. While slower growing than most other groundcover manzanitas, this cultivar will eventually reach about 6 ft wide with a height of about 1 ft. 'Mount Vision' is best planted as a specimen rather than in mass plantings. Very drought tolerant once established with full sun to light shade. An excellent container plant.
Arctostaphylos hookeri ‘Monterey Carpet’
Evergreen, creeping manzanita less than 1 ft. tall with small, deep green leaves. Dark red branches tend to root and increase its spread to 8 ft. or so wide. Small clusters of white flowers appear in late winter to early spring. Prefers a little shade inland. Drought tolerant but enjoys occasional irrigation in inland sites. Perfect under deciduous oaks or tall pines. Works well in spots where the creeping branches can spill over an edge, creating a cascade effect.

A low growing, spreading manzanita with lustrous green, rounded foliage, little pink urn-shaped flowers and pretty red berries, quite large for the species. This selection from coastal Oregon spreads at a moderate pace to 6-8 feet wide and only getting 6-8 inches tall. Full sun to light shade in hot areas with moderate summer water.

This delighful perennial grows 1 - 2 feet tall and wide with cheerful, bright golden-yellow daisies in early summer. The bright green, lance-shaped leaves sit in opposite pairs along them stems. Grow in full sun to light shade with decent draining soils and regular moisture. Said to have the same medicinal properties of its European cousin, but easier to grow. Flowers support bees, bumblebees and butterflies. Winter deciduous. Deer resistant.
Artemisia californica ‘Canyon Gray’
An unusual prostrate form of our coastal native sagebrush, forming a loose, nearly flat mat of finely cut, silvery, fragrant foliage around 4 ft. wide. Useful as a bank cover or for the top of a retaining wall where it can cascade over the edge. Combines beatifully with ceanothus, buckwheats and iris. Should be cut back from time to time to keep dense. Enjoys full sun to light shade and is very drought tolerant once established. Deer resistant.
Artemisia californica ‘Montara’
Selected by Roger Raiche at Montara Ridge in San Mateo County. Forms a mound of finely cut fragrant foliage to around 2 ft. tall by 3 ft. (or more) wide. Requires full sun with decent drainage and is drought tolerant once established. Occasional summer water helps retain fresh look. Thrives in coastal environments. Deer resistant.
Artemisia pycnocephala ‘David’s Choice’
