1. California false indigo – Amorpha californica (a-MOR-fuh kal-ih-FOR-ni-kuh) Family: Fabaceae (Pea Family) Native to: Mountains of western CA from N. CA south, AZ and Baja CA. Locally in the Santa Monica & San Gabriel mtns.; shrubby or open slopes in slopes in Yellow Pine Forest, Chaparral, Mixed Evergreen Forest, Oak Woodland and riparian woodlands. Growth characteristics: woody shrub mature height: 4-8 ft. mature width: 4-8 ft. Open, drought-deciduous shrub with hairy, scented foliage. Leaves are compound, to 12” in length, medium green, with hair-like glands. Leaves smaller than similar Amorpha fruticosa. Plant shape very dependent on light – more rounded, shrubby in more light, groundcover-like in lower light. The foliage has pleasant fragrance – like tropical fruit perhaps combined with lavender. Wonderful! Blooms/fruits: Blooms are unusual. Plants flower in spring – usually Apr-June in our area. Inflorescence (flower cluster) is spike-like. Individual flowers are small, somewhat pea-like with prominent purple sepals and reproductive structures extending beyond the fused sepals. This plant is exotic looking when in bloom. The flower stalks are subtle but so unusual as to draw attention. Uses in the garden: Usually planted for its habitat value. Larval food source for California’s state butterfly, the California Dogface (Zerene eurydice). Nice addition to a scent garden. Does well in shady or partly shady areas, under trees. Fine on shady slopes, stream banks. The foliage is so different that it provides a nice contrast with other local native shrubs. Fine in large containers. Sensible substitute for: Non-native shrubs in Pea Family like Psoralea pinnata, Caragana species. Attracts: Excellent butterfly and hummingbird habitat (see above). Requirements: Element Requirement Sun Filtered sun to nearly full shade Soil Adaptable; most local textures including sand, pH 6.0-8.0 Water Drought tolerance but best with occasional summer water (Water Zone 1-2 to 2) Fertilizer Not required, except in container; light doses Other Fine with organic mulch – in fact, probably best with mulch Management: The only issue is summer irrigation schedule. Other than that, easy once established in a shady spot. Prune when dormant; can shape but best to just remove old branches. Propagation: from seed: easy from fresh; 21 days cold-moist for stored by cuttings/layering: yes Plant/seed sources (see list for source numbers): 8, 10, 13 7/1/14 © Project SOUND
CA Buckwheat – Eriogonum fasciculatum vars. fasciculatum & foliolosum (air-ee-OG-oh-num fas-sick-yoo-LAY-tum) Family: Polygonaceae (Buckwheat Family) Native to: Central coast of CA south to Baja; var. fasciculatum grows in coastal areas in coastal scrub, coastal sage scrub and on bluffs. Var. foliolosum on rocky/sandy flats and slopes in mixed grassland, chaparral communities, oak and conifer woodlands. Growth characteristics: clumping sub-shrub mature height: 2-5 ft. mature width: 4-5 ft. Evergreen, many-branched sub-shrub. May be upright or more reclining. Leaves are linear, dark green on top and white beneath, in bundles (fascicles – hence the name). Blooms/fruits: Blooms off and on throughout the year, but mostly from May to Nov. Flowers are small, pink-white, in dense clusters. Very showy in bloom! Seed heads are rust-brown, also quite showy. Plant looks nice most of the year. Uses in the garden: Plant is often used in habitat gardens. Is nice paired with other local native shrubs and perennials. Does well as a groundcover on hills and slopes. Cultivars 'Bruce Dickinson', ‘'Theodore Payne' and 'Warriner Lytle' are all low-lying forms (around 1 ft tall). Cultivar ‘Dana Point’ has brighter green leaf and mounded habit – grows to 5+ ft. wide. Sensible substitute for: Non-native summer-flowering shrubs. Attracts: Excellent butterfly habitat plant: larval food source for Morman Metalmark, Bramble Hairstreak, Common Hairstreak, Avalon Hairstreak. Birds love the seeds. Cover for birds, lizards. Requirements: Element Requirement Sun Full sun best; some shade OK, but will become leggy. Soil Any (sand to clay) but well-drained is best. Water Drought-tolerant but looks better with occasional summer water (Zone 1-2 to 2) Fertilizer None needed. Other Management: Fairly easy. Cut back to about 6-15” in late fall to keep it looking nice. Propagation: from seed: yes; may need cold treatment by cuttings: yes Plant/seed sources (see list for source numbers): 1, 3, 7, 8, 10, 12-14, 16, 17, 19, 20, 23, 24, 46, 50 7/3/10 © Project SOUND

Growth characteristics: perennial sub-shrub mature height: 2-4 ft mature width: 2-4 ft Erect, herbaceous/woody perennial with alternate, leathery leaves. Leaves, stems and flowers are sticky-resinous. Plant may be upright or more decumbent – definitely an informal appearance. Blooms/fruits: Attractive yellow “daisy” flowers from Mar-Oct. Bracts below heads are down- curved. Uses in the garden: In informal cultivated beds (mid-bed). Good for sandy, relatively infertile soils. Flowers attractive, numerous, long-lasting. Scented (balsamic scent). Great for butterfly, pollinator or bird garden – excellent all-round habitat plant. Looks great with blue or purple flowers, or with native bunch grasses. Good for dry gardens (xeriscaping) or salty/alkali soils. Tough plant! Sensible substitute for: non-native bush sunflowers: Gloriosa Daisies (Rudbeckia), Chrysanthemums Attracts: Butterflies; many species of bees; beetles and other interesting insects. Birds eat seeds. Requirements: Element Requirement Sun Full sun Soil Sandy to medium – well-drained best but tolerates clay; pH 6-8 Water Low needs, particularly when flowering. Will tolerate more if soil well-drained Fertilizer None needed Other Tolerates alkali and salty soils Management: Easy to grow. Cut back to near the ground after flowering to keep from getting leggy. Dies back significantly in dry conditions. Propagation: from seed: Easy. Collect seed from dry heads in summer/fall. Seeds may be dried and stored for planting in spring. In S. Bay can be planted in pots or in the ground Oct-Nov. Plant/seed sources (see list for source numbers): 1, 2, 6, 8, 12-14, 16, 20, 24, 31 7/3/14 © Project SOUND

CA to OR (ssp. microcephala from S. CA south to Baja; ssp. beneolens from San Gabriel mtns); common on dry slopes and in open, grassy places in chaparral, coastal sage scrub, and southern oak woodlands below 4000'. Growth characteristics: herbaceous perennial mature height: 2-4 ft. mature width: 2-4 ft. Short-lived (2-4 years in our area) herbaceous perennial wildflower from a woody root. Habit is open, branching, may droop in part-sun; graceful. Foliage intensely white-wooly; really stands out. Blooms/fruits: Blooms summer to fall - July into Nov. along the coast. Flowers small, in loose clusters are the ends of flowering stalks. Flowers too small to be really showy – but attract many small bees and other pollinators. Uses in the garden: Most effective as a silvery accent among darker-colored foliage. A necessity for the butterfly garden. Great with its natural associates: native bunch grasses, annual wildflowers. Sensible substitute for: Non-native white-foliage plants like Dusty Miller. Attracts: Excellent pollinator habitat. Larval food for American Lady Butterfly – larval will make a ‘shelter’ of leaves & silk to protect themselves from predation. Birds eat seed. Requirements: Element Requirement Sun Full sun to part-shade; more compact in full sun. Soil Just about any local soil. Water Not particular; anything from Zone 1 (with annual wildflowers) to Zone 2. Fertilizer Not needed – but wouldn’t kill it. Other Management: Pretty much manages itself. Cut back if it becomes unruly.
