Important northern California native habitat plant that is the sole larval food source for the pipevine swallowtail butterfly. This deciduous vine grows naturally along stream banks and in woodlands and performs well under native oaks. Dutchman’s pipevine is relatively slow-growing and takes a few years to establish. Pendulous pipe-shaped flowers bloom in early spring, followed by soft, bright green, heart-shaped leaves. Best grown as a groundcover to provide protection for pipevine swallowtail larvae but will also twine up other plants and structures. The real show comes in late spring as larvae feed on the plant and grow into spectacular horned, black caterpillars with red spots!

Large group of plants that includes annuals, perennials, and shrubs grown for fine, soft-textured, aromatic, gray-green foliage. Flowers are inconspicuous but provide a source of pollen, nectar, and seeds for wildlife. Shrubby varieties can be cut back to maintain a more tidy and compact appearance. Perennial varieties can be divided in fall or early spring. Excellent choice as support for more showy plants in the garden.

Examples: A. ‘Powis Castle’ (3’ x 6’), A. californica (2-5’ x 4-5’, low-growing cultivars ‘Canyon Gray’ and ‘Montara’), A. pycnocephala ‘David’s Choice’ (6” x 2’).

Ceanothus is a group of fast-growing, evergreen shrubs that vary from groundcovers to small trees, many of which are native to California. They provide a spectacular display of flowers in spring that will attract a multitude of pollinators. Flowers are followed by seeds that provide food for birds. The clusters of tiny flowers range from white to deep violet. Plants perform best with good drainage and minimal irrigation once established. Some do best in cooler coastal climates, but many thrive in hotter inland climates. Pay close attention to the mature size when selecting ceanothus to ensure that it has sufficient space for its natural form.

Groundcovers: C. ‘Centennial’ (1’ x 8’), C. gloriosus var. gloriosus ‘Anchor Bay’ (2’ x 8’), C. griseus var. horizontalis ‘Diamond Heights’ (variegated, 1’ x 4’), C. griseus var. horizontalis ‘Yankee Point’ (3’ x 12’), C. maritimus (2’ x 6’).

Shrubs: C. ‘Blue Jeans’ (6’ x 6’), C. Concha (6’ x 6’), C. ‘Dark Star’ (6’ x 8’), C. ‘Joyce Coulter’ (4’ x 12’), C. ‘Julia Phelps’ (8’ x 10’), C. cuneatus (8’ x 8’), C. thyrsiflorus ‘Skylark’ (4’ x 6’).

Large shrubs: C. ‘Frosty Blue’ (10’ x 12’), C. thyrsiflorus (20’ x 20’), C. t. ‘Snow Flurry’ (white flower, 20’ x 20’).

Trees: C. ‘Ray Hartman’ (15′ x 15′)

California native, evergreen shrub or small tree often seen growing in Sonoma and Marin county wildlands. Lacy, white flower clusters in spring attract pollinators; red berries in winter provide a splash of color and an important food source for birds. The name “Hollywood” was born from the abundance of toyon in the hills of southern California and its resemblance to European holly. The cultivar ‘Davis Gold’ has yellow berries and may be more disease-resistant than the species.

Iris are a large and diverse group of perennials that grow from either bulbs or rhizomes. The California native Douglas iris and cultivars known as Pacific Coast Hybrids are an excellent choice for summer-dry gardens and understory plantings. Fall rain brings new growth in the form of thin, upright leaves, followed in late winter to early spring by the first blossoms. Douglas iris commonly ranges in color from lavender to purple, but cultivars are available in a range of colors including white and yellow. Established plantings can be lifted and divided after the first significant fall rain and either replanted or put into containers to share with others.

Coyote Mint is a compact perennial or sub-shrub with aromatic foliage and a sprawling habit. Dense heads of purple flowers form in spring-to-summer that are attractive to butterflies and other insects. The low-growth habit of coyote mint makes it an excellent choice for the front of a border, along the edge of a path, or beneath larger shrubs such as manzanita or ceanothus. Monardella villosa spp. franciscana ‘Russian River’ and Monardella villosa spp. villosa ‘Mark West’ are available selections from Sonoma County.

Salvias are a huge group of more than 900 species that include annuals, perennials, and shrubs adapted to a variety of climates and have varying water requirements. Salvias are attractive to hummingbirds, butterflies, and bees, and are generally ignored by deer. Sages that are native to California are generally drought-tolerant, prefer full sun, and little to no fertilizer. Annual pruning in late summer or fall generally helps to keep plants tidy and healthy.

CA native sages:

• S. apiana, white sage (3-4’ x 4-6’), silvery-white, aromatic leaves with tall flower spikes of white flowers, popular for honey production and in bundles as a natural incense.
• ‘Bee’s Bliss’ (1-2’ x 6-8’), superb, light gray groundcover with light purple flowers on long spikes; damp conditions can cause mildew which will clear with warm weather and sunny conditions.
• S. clevelandii, Cleveland sage (3-5’ x 3-5’), medium-sized shrub for hot, dry locations known for pleasant fragrance and deep blue whorls of flowers; popular cultivars include S. c. ‘Allen Chickering’, S. c. ‘Pozo Blue’, and S. c. ‘Winnifred Gilman’.
• S. leucophylla, purple sage, includes plants with both an upright growth habit, such as S. l. ‘Amethyst Bluff’ (3-5’ x 3-5’) and others with a sprawling form, such as S. l. ‘Point Sal’ (2-3’ x 6’), both of which are from Santa Barbara county.
• S. sonomaensis, Sonoma sage (1-2’ x 3-4’), groundcover that prefers light shade and will not tolerate damp conditions; cultivars include S. s. ‘Dara’s Choice’, S. s. ‘Greenberg Gray’, and S. s. ‘Hobbit Toes’.
• S. spathacaea, hummingbird sage (1-2’ spreading), herbaceous groundcover that grows well in dry shade and spreads slowly by underground rhizomes; large leaves have a wonderful fruity fragrance; the only red-flowered native sage.
• S. mellifera, black sage (6′ x 10′), evergreen shrub that grows well in full sun and well drained soils. Dark green leaves with pale purple flowers in late spring and early summer.

Non-native sages:

• S. chamaedryoides, germander sage (2-3’)
• S. chiapensis, Chiapas sage (1-2’ x 3-4’)
• S. greggii, autumn sage (1-4’ x 1-4’)
• S. leucantha, Mexican bush sage (3-4’ x 3-6’)
• S. microphylla, cherry sage (3-4’ x 3-6’)
• S. officinalis, garden sage (1-3’ x 1-3’)

Fast-growing shrubs and small trees for sun or part shade that attract pollinators from far and wide to large clusters of cream flowers in spring, followed by berries in summer that provide food to many types of birds. Fruit can also be used for culinary purposes. While naturally fairly wild-looking, elderberries can handle being cut back to the ground in the winter or pruned to maintain size and shape.

Examples:

• Blue elderberry (S. mexicana [nigra] spp. caerulea, 8-25’) is native from Oregon to Baja California and beyond.
• Black elderberry (S. nigra, 20-30’) is native to Europe, North Africa, and Asia, and is available in nurseries in the form of many named cultivars. Cut leaf black elderberry (S. n. ‘Black Lace’, 8’ x 8’) has intense dark, fine foliage. Cut leaf elderberry (S. n. ‘Laciniata’, 10’ x 10’) has green leaves, and variegated black elderberry (S. n. ‘Marginata’, 6-12’) has variegated leaves.
