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: 3-4 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.
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

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 to maintain. Cut back to about 6” in late fall to keep it looking nice.

Soil Any well-drained; any pH is fine
Water Tolerates some supplemental water in summer (better fruiting); keep leaves dry (susceptible to fungal diseases)
Fertilizer None needed
Other
Management: prune yearly (Feb-Mar) to maintain shape. Flowers/fruits borne on year old wood.
Watch for fungal disease, particularly in warm, wet weather.
Propagation: from seed: relatively easy in winter/spring. Soak berries in water about 1 week then rub through sieve to clean. Store dry seeds cool. Plant shallow. Sow 10-20 seeds/cup.

Native to: Much of southern U.S. to S. America, Caribbeans. In CA, mostly w. of Sierras, but also in s. desert areas; common in moist soil including saline valley bottoms, coastal salt marshes,
freshwater marshes, washes & riparian areas.
Growth characteristics: clumping sub-shrub mature height: 2-4 ft. mature width: 2-3 ft. Semi-woody sub-shrub with faint camphor-like fragrance. Leaves rounded to lance-shaped, gland-
dotted, clustered towards the branch tips. Stress-deciduous (looses leaves in drought; cold); may be an annual in colder climates. Plants have many, upright stalks. Spreads via rhizomes.
Blooms/fruits: Blooms in late summer through fall (July-Aug through Oct.). Flowers typical of Sunflower family. Fragrant, pink/lavender flower heads are numerous in dense, flat-topped clusters at ends of branches – quite showy and unique, especially in Fall. Seeds have fluffy bristles.
Uses in the garden: Excellent choice for moister areas of garden (rain gardens; swales; under
birdbath; etc). Fine along streams, near ponds. Does well in large containers, but will be smaller
than in the ground. Great fall habitat plant! Used medicinally in Caribbean countries. Crushed leaves serve as an insect repellant.
Sensible substitute for: Non-native fall-blooming plants like chrysanthemums.
Attracts: Excellent bird & pollinator habitat. Provides cover and seeds for bird food. Native
pollinators love the nectar.
Requirements:
Element Requirement
Sun Quite adaptable; full sun to fairly shady
Soil Just about any except very coarse/rocky; alkaline and salty soils are fine
Water Prefers regular water but ok (will go dormant) with less summer water; Zone 2 to 3
Fertilizer Not needed, but not a problem; fertilize lightly if grown in container
Other
Management: Prune back in winter if leggy. Will spread via rhizomes, so may want to contain.
Propagation: from seed: direct seed in fall; may benefit from pre-chill by cuttings: probably

canyons, coastal-sage scrub.
Growth characteristics: perennial sub-shrub mature height: 2-5 ft. mature width: 3-5+ ft.
Open sub-shrub with woody base and mostly herbaceous branches. Leaves mostly basal, coarsely-toothed somewhat like a dandelion or a white-flowered Chicory. Branches are wire-like. Summer
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.
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.
Requirements:
Element Requirement
Sun Full sun best; light shade probably fine.
Soil Probably any texture or local pH
Water Little summer water once established (Zone 1/2)
Fertilizer None
Other
Management: Little management needed. Hardy plant. Cut back if it gets straggly.

Hooker’s Evening Primrose – Oenothera elata ssp. hirsutissima & hookeri (ee-no-THEE-ruh el-AH (or LAY)-tuh)
Family: Onagraceae (Evening Primrose Family)
Native to: Much of California & U.S. southwest (ssp. hirsutissima) and S. CA (ssp. hookeri);
generally moist or seasonally moist places, meadows, bluffs.
Growth characteristics: herbaceous biennial/perennial mature height:3-6 ft. mature width: 4 ft.
Herbacious biennial that may be a short-lived perennial or even an annual in our climate. In nature, first year is just a rosette of leaves – flowers the second year. Basal leaves are large (to 6”) gray-
green. Mature plant has one main stalk with many side branches.
Blooms/fruits: Blooms for long period in summer into fall (July or Aug though Oct.). Blooms open
sequentially. Blooms are large (1 inch), bright lemon-yellow, showy. Flowers open in late
afternoon and remain open until sun hits them the next morning. Nice summer floral color.
Uses in the garden: Most often used in natural plantings, but fine in other dry garden settings.
Good with native grasses, annual & perennial wildflowers. Just remember that it gets big & it re-seeds. Roots can be cooked and eaten. Young foliage can be eaten as raw or cooked greens. Sensible substitute for: Non-native Evening Primroses.
Attracts: Excellent habitat plant: provides nectar for moths, large bees & hummingbirds & seeds
for seed-eating birds.
Requirements:
Element Requirement
Sun Full sun to part-shade
Soil Light to medium soils best; does great in sandy/rocky soils
Water Wide range of tolerance: Zone 1-2 to 2-3 (little to occasional summer water)
Fertilizer None needed; but not a problem
Other
Management: Simplicity itself to grow from seed. Re-seeds very well – just pull up the ones you
don’t want in late spring. Propagation: from seed: in prepared beds, fall to spring. No pretreatment required.

Growth characteristics: herbaceous perennial mature height: 1 ft. mature width: 2-5+ ft. Herbaceous perennial with slender rootstock. Spreads via root laterals, seed. Leaves medium-
green, initially in basal rosette. Stalks initially upright, then reclining to almost vine-like. Stress
deciduous – can die back during summer drought.
Blooms/fruits: Blooms in spring – usually Apr-May in our area. Flowers are large, pink-white and
sweetly fragrant. Plant is very showy in bloom, blends in otherwise.

annual wildflowers. Good choice for parking strip. Nice in pots or planters placed where you can
enjoy the fragrant flowers. White flowers mix well with other flowering natives.
Sensible substitute for: Non-native Primroses, white-flowered perennials.
Attracts: Excellent butterfly & moth habitat – good nectar source.
Requirements:
Element Requirement
