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

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.

coast; uncommon on dry cliffs and bluffs, coastal grassland and scrub communities < 1000 ft.

Growth characteristics: perennial/sub-shrub mature height: 1-2 ft. mature width: 1-4 ft.

Spreading low sub-shrub, evergreen except in serious drought with green to silvery-green foliage.

Mounded form. Leaves are oval or spoon-shaped, somewhat crinkled and larger than many local

deciduous with no summer water.

Blooms/fruits: Blooms much of the year in lower elevations (Mar-Nov) depending on rainfall.

Flowering heads typical of sunflower family, white with pink striping, solitary along the wire-like

branches. Quite showy, as there are often many blooms at one time.

Uses in the garden: Right at home in the water-wise garden. Does well on slopes and in rock

gardens, near rock walls or fences. Airy-looking white flowers mix well in perennial beds. Probably fine in large pots or planters. Flowers are a refreshing contrast to dark leaves of native shrubs.

Plant makes a nice filler and will re-seed naturally. Very tough plant that looks best in wet years.

Sensible substitute for: Non-native perennial sunflowers like Asters.

Attracts: Good bird, butterfly and insect habitat: provides Fall nectar and seeds for food. Rabbits like foliage.

* Desert Mallow – Sphaeralcea ambigua (sfeer-AL-see-uh am-BIG-yoo-uh)

Family: Malvaceae (Mallow Family)

Native to: Southwestern deserts & desert mountains. In CA, in both Mojave & Sonoran Deserts; on

sandy or rocky soils, mostly in washes, canyons or on dry slopes.

Growth characteristics: perennial sub-shrub mature height: 3-4 ft. mature width: 2-3 ft.

Lovely, mounded evergreen sub-shrub with typical mallow leaves & other features. Many slender,

semi-woody stems. Leaves are gray-green, covered with hairs (allergenic – wear gloves when handling). Airy, looks like a garden plant. Fast growing. Short-lived, but re-seeds well.

Blooms/fruits: Blooms mostly in spring (Mar-June) but year-round with some water. Flowers

range from white to pink-purple, but most are apricot to red-orange. One of the largest flowers of native Globe-mallows. Flowers look like small Hibiscus flowers on Hollyhock-like stems.

Uses in the garden: Makes lovely addition to cottage garden or other garden that features flowering

plants. Excellent choice for water-wise garden, desert garden or rock garden. Works great on dry

slopes and fine in hot, sunny areas. Fine in containers. Not for the immediate coast (too foggy).

Sensible substitute for: Non-native Mallows, Hollyhocks, other small flowering shrubs.

Attracts: Excellent habitat: plant : provides cover and seeds for bird food and nectar for insect

pollinators. Larval food source for Western Checkered White butterfly.

Requirements:

Element Requirement

Sun Full sun – even areas with hot, reflected sun

Soil Sandy or rocky; must be well-drained; any local pH, including alkali

Water None needed (Zone 1), but looks better (and flowers longer) with occasional water (Zone 2)

Fertilizer None needed; light fertilizer won’t kill it.

Other

Management: Low maintenance plant. Shear back to 6 inches in fall to rejuvenate (some do this every year). Short-lived but re-seeds well (dead-head to prevent reseeding).

Propagation: from seed: easy in fall; soak older seed overnight by cuttings: difficult

White (Felt-leaf) Everlasting – Pseudognaphalium canescens (sue-doh-na-FAY-lee-um kan-ES-ens)

Family: Asteraceae (Sunflower Family)

Native to: Coastal areas & coastal foothills from S. 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.
