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′)

The orange, tubular flowers of sticky monkey flower can be enjoyed in many locations throughout Sonoma and Marin counties in spring and summer, a testament to how well this plant is adapted to hot and dry conditions. The slightly sticky leaves benefit from light pinching and pruning to maintain an attractive appearance and support for the beautiful flowers. Many hybrids provide color variation. Do not confuse this plant with the red-flowered scarlet monkey flower (Mimulus cardinalis), an herbaceous riparian plant that requires regular water to thrive.

Penstemons are a large group of woody or herbaceous perennials with narrow leaves and tubular flowers. Foothill penstemon is a widely known and grown California native with iridescent purple-blue flowers during spring and early summer that are attractive to hummingbirds. The cultivar known as ‘Margarita BOP’ is widely available, reliable, and garden- tolerant. Remove spent flower spikes to encourage more flowers.

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’)
