Aloysia citriodora is a fast growing, evergreen shrub. They can reach to 6 feet or more once completely grown. These have a unique lemon scent, it brings a bright zesty smell and taste rather than other lemony herbs. The plant brings beauty to a landscape with its refreshing scent as well as the white and purple colors to compliment the scenery.

Group of evergreen trees and large shrubs with attractive foliage and bark, small urn-shaped flowers, and reddish fruit. Prefer sunny locations and well-drained soil. A. ‘Marina’ (20-30’ – 15-30’) and A. unedo (strawberry tree, 15-30’ x 15-30’) are most commonly planted in California landscapes, either as multi-stemmed or single-stemmed, large shrubs or trees. While the two trees are similar in appearance, A. ‘Marina’ has cinnamon-brown shedding bark, whereas the bark of A. unedo is more brown. A. menziesii (madrone, 20-100’) is native to the west coast of North America, including the foothills of Sonoma and Marin counties. A. menziesii is less common in landscapes as it is notoriously difficult to establish.

California gray rush is a go-to species for the summer-dry rain garden. It will thrive in moist conditions and its roots will help stabilize soil and filter stormwater runoff. It is also tolerant of extended periods of drought. Clumps of stiff, upright foliage provide an interesting contrast among other perennials. ‘Elk Blue’ is a widely available selection from Mendocino County. Its bluish gray foliage is shorter than the typical gray rush.

Some barberries may be referred to either as Berberis or Mahonia. The California species are a group of evergreen shrubs with glossy, spiny-edged leaves and clusters of yellow flowers in spring followed by small grape-like berries attractive to birds. Barberry foliage provides a display through the year as new leaf growth is often bronzy red that gives way to green- and finally purple-red tones in the winter months.

Examples: Oregon grape (M. repens, 1-3’ x 2-3’) is an excellent small-scale groundcover for lightly shaded understory locations; Nevin mahonia (M. nevinii, 6-8’ x 6-8’) with blue-green leaves from Southern California is a good screen plant; and California holly grape (M. pinnata, 4-6’ x 4-6’) with wavy leaves provides distinctive texture.

Low-growing, flowering perennial from the mint family that produces many spikes of lavender flowers in the summer that are attractive to bees, butterflies, and hummingbirds. Soft, gray-green, aromatic foliage is attractive to cats. Nepeta species seed freely and may become invasive. Nepeta x faassenii is a sterile hybrid that is widely available and grows well in Northern California gardens. Available cultivars have flowers ranging from deep blue to white.

Currants (without spines) and gooseberries (with spines) are grown for their graceful growth habit, attractive foliage, wonderful displays of pendulous flowers in winter-spring that are attractive to hummingbirds, and colorful fruit that provides a food source for birds. Most of the species listed are deciduous, going dormant in the summer months.

Examples: Some of the species suitable for California gardens, preferably with partial shade, are native to the Western United States:

• aureum, golden currant (5-10’ x 3-6’), deciduous with small clusters of delicate yellow flowers and sprawling habit.
• malvaceum, chaparral currant (4-8’ x 4-6’), deciduous with early clusters of pink flowers, a slightly vase-shaped habit, and more drought-tolerant than most species.
• sanguineum var. glutinosum, pink-flowering currant (5-12’ x 5-12’), deciduous with maple-like leaves, a vase-shaped habit, and long pendulous clusters of pink, reddish, or white flowers in the spring; many available cultivars such as ‘Claremont’, ‘Tranquillon Ridge’, and ‘White Icicle’.
• speciosum, fuchsia-flowered gooseberry (4-8’ x 6-10’), deciduous with spiny, arching stems and bright red fuchsia-like flowers along the stems in the spring that are attractive to hummingbirds.
• viburnifolium, evergreen currant or Catalina perfume (2-4’ x 5-7’), evergreen groundcover that works well under oaks and can provide erosion control to slopes.

Classic Mediterranean flowering shrub with aromatic foliage, small blue-lavender flowers in late winter and spring that attract butterflies and bees. Thrives in full sun with well-drained soil and makes a good container plant. Rosemary is an excellent plant to have in the garden for harvesting fresh springs for use in cooking. Cuttings root readily, making it relatively easy to propagate new plants. Many named cultivars provide variation in size, growth form, flavor, and fragrance.

Examples: R. o. ‘Barbeque’ (3-5’ x 2-3’) has tall, upright stems that can be used as skewers for grilling; R. o. ‘Blue Spires’ (4-5’ x 2-3’); R. o. ‘Collingwood Ingram’ (2-3’ x 3-6’) is lower-growing with arching branches; R. o. ‘Huntington Carpet’ (1-2’ x 4-8’) is very low-growing; R. o. ‘Irene’ (1-2’ x 2-3’) has a mounding habit; R. o. ‘Prostratus’ (2’ x 4-8’) has a trailing habit that works well cascading over a retaining wall.

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.
