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 grass-like, clumping plants with low or moderate water needs that are native to many parts of the world and offer a variety of shapes, sizes, and foliage characteristics. Some sedges are ideal for use in rain gardens and swales, for stabilizing slopes, as a mass groundcover, or as part of a meadow planting. Two low-water examples that prefer some shade are Catlin sedge (C. texensis, 4-6” x 6-8”), a small, mat-like sedge native to central and southwestern North America, and Berkeley sedge (C. tumulicola, 1-2’ x 1-2’), a larger species native to western North America that tends to self-sow. Other species require more water and may be less suited to dry inland conditions. Some species can be invasive and difficult to control.

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’).

Western redbud is an ornamental, multi-trunked and deciduous, large shrub or small tree with year-round interest that provides a California native and very low-water alternative to the moderate-water Cercis canadensis. Magenta to rosy pink blossoms that resemble pea flowers cover bare branches in late winter to early spring. Apple green, heart-shaped leaves emerge to accompany the flowers. Over the summer, the leaves become more leathery and bluish green, and seed pods mature and remain into the winter months.

Clumping perennial with stiff, upright, jointed stems that contrast well with other plants. Tan-colored bracts form at the stem joints in summer and fall, providing a striking display. Two species from South Africa grow well in California gardens, especially in rain gardens and swales since they will tolerate both standing water and dry conditions, once established. C. elephantinum (4-5’ x 4-10’) is the larger of the two, C. tectorum (3-4’ x 3-5’) is more suitable for smaller spaces.

Diverse group of flowering, evergreen shrubs and perennials and annuals found throughout the western United States. Most available in nurseries are native to California and generally prefer drier sites. Flowers colors include yellow, white, pink, and red and are held above foliage in umbels that dry over time and are popular in flower arrangements. Buckwheats provide pollen and nectar for bees and butterflies, larval food for butterflies, seeds for birds, and cover for many creatures.

Examples:

• Santa Cruz Island buckwheat (E. arborescens, 3-4’ x 4-5’) densely mounded with white flowers.
• Saffron buckwheat (E. crocatum, 1-2’ x 2-3’) with chartreuse-yellow flowers and pale leaves.
• California buckwheat (E. fasciculatum, 2-3’ x 3’) and its low-growing cultivars such as E. f. ‘Warriner Lytle.’
• Catherine’s lace (E. giganteum, 4-8’ x 6-10’) with delicate, white flowers and soft pale leaves.
• Red-flowered buckwheat (E. grande var. Rubescens, 1-2’ x 2-3’) low-mounding perennial with rose-pink flowers, coastal bluff buckwheat (E. latifolium, up to 12” x 1-2’.)

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.
