Acer circinatum
Deciduous shrub or tree 5 to 20 ft. tall, native to moist woods and streambanks in the coastal mountains of northern California to British Columbia. Attractive in all seasons: bare reddish twigs in winter, delicate lobed leaves in spring and summer, and good color in autumn. Wonderful in the woodland setting, under tall conifers where its fall color will stand out. A natural with ferns and other woodland plants that receive dappled to part shade and regular to moderate summer water. Can be espaliered too.
Acer macrophyllum
This stately and picturesque tree is native to stream banks and moist canyons from Southern Alaska to the foothills of California. A large, round-topped tree with large dark green lobed leaves and smooth silver-gray bark. Fast growing 30 ft or more tall. One of the few native trees to offer good fall color. Sun to partial shade, occasional to regular water. When planting in a sunny location, protect the trunk from sun-scald with a dilute application of white latex paint.
Acer negundo var. californicum
The box elder at maturity features a broad canopy supported by thick branches and a wide, gray trunk. In spring, the silky pink inflorescences hang from the tips of the branches as the leaves begin to emerge. Quickly grows to a height and width of up to 50 ft. Often used as a restoration plant in riparian zones. Full sun to part shade. Enjoys regular moisture. Deer seem to leave it alone once established.
Achillea millefolium – Bodega Bay form
Larger leaves up to 10 inches long distinguish this form from most other local yarrow selections. While most yarrow from our coastline have very green leaves, this strain is on the grey side. From spring through autumn, large white flower clusters sit upon stalks about to at least 2 feet in height. Water occasionally in areas away from the coast and provide full sun. The foliage is deer resistant.
Achillea millefolium – inland form – Lake County seed source

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.
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.

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 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.
