  • 1. * White Alder Alnus rhombifolia (AL-nus rom-bee-FOH-lee-uh)Family: Betulaceae (Birch Family)Native to: Western United States from Baja to British Columbia. In California, much of the stateexcept the Mojave Desert, including the Santa Monica & San Gabriel Mtns; along stream banks,canyon bottomlands and gulches to about 7000 ft., often in small stands along permanent streams.Growth characteristics: woody tree mature height: 40-70+ ft. mature width: 30-40 ft.Lovely winter-deciduous tree with striking white-gray bark. Fast growing to 30 ft. in less than adecade. Leaves alternate, rounded with serrated edges, prominent veins shiny above. Leaveson long petioles (stalks) so they quiver in the wind. May have one or several trunks. Sweetfragrance. Roots are invasive (water-seeking) and may damage sidewalks/concrete.Blooms/fruits: Blooms in winter/early spring in our area. Separate male and female flowers oneach tree. Male flowers on drooping branches (catkins); female flowers develop into small, woodycones < 1 inch long. Wind pollinated. Seeds are small spread by wind and water.Uses in the garden: Usually planted as a lawn tree in large lawns or as a street tree. Provides goodshade few other plants can grow beneath it when mature. Excellent choice for stream banks andmoist, shady canyons.Sensible substitute for: Non-native deciduous trees.Attracts: Excellent bird habitat: provides cover, nest sites and seeds for food.Requirements:Element RequirementSun Full sun to part-shade.Soil Any local.Water Needs regular summer water Water Zone 2-3 or 3.Fertilizer Not needed probably not harmful.Other Use an organic mulch (or let leaf mulch accumulate).Management: Watch for Alder Borers, which can kill trees. Relatively short-lived (to 80 years).Can prune up to a more open shape.Propagation: from seed: fresh seed in fall; 180 day cold-treat stored seed by cuttings: yesPlant/seed sources (see list for source numbers): 1, 3, 6, 8, 13, 14 4/30/13 Project SOUND

2. *Tanbark Oak Notholithocarpus densiflorus (no-tho-lith-oh-KAR-pus den-si-FLOR-us )Family: Fagaceae (Beech/Oak Family)Native to: Primarily grows in Coastal Ranges of CA and OR from Ventura and Santa BarbaraCounties northward; on wooded slopes in humid Redwood, Mixed Evergreen, Yellow Pine Forest andRed Fir Forests up to about 4500 ft. elevation. Formerly called Lithocarpus densiflorus.Growth characteristics: woody tree mature height: 50-75 ft. mature width: 25-40 ft.Elegant evergreen woody tree; broad in open areas or more shrubby in shade. Leaves are toothedwith a hard, leathery texture. Young leaves covered in orange hairs which persist only on underside.Bark is thick, gray and fissured tannins extracted from bark were used to tan leather. Forms aburl at base. Relatively slow-growing (to 8 ft in 5 yr.). Plants are very susceptible to sudden oakdeath (Phytophthora ramorum) disease.Blooms/fruits: Blooms in spring/summer. Male catkins are long and drooping (like oak) whilefemale flowers (which produce fruit) are nearly inconspicuous. Trees can be covered in malecatkins in a good year quite dramatic! The seeds, which resemble acorns with a very hard shell,take 2 years to develop and ripen in fall. Seeds contain high levels of tannins but are edible ifprocessed to remove them. The seeds were an important food crop for Native Californians.Uses in the garden: Most suited for woodland garden with redwoods and pines. Lovely trees would do well in a watered lawn in our area.Sensible substitute for: Non-native hardwood trees.Attracts: Excellent habitat plant: provides cover, nest sites and seeds for food.Requirements:Element RequirementSun Part-shade; good to east of taller treesSoil Well-drained, deep soils best; pH: 5:00-7:00 best.Water Needs summer irrigation Water Zone 2-3 (water every 1-2 weeks).Fertilizer Would be fine.Other Use an organic mulch (like redwood bark) or plant grasses beneath.Management: Prune out dead branches as needed.Propagation: from seed: fresh seed; stratify 2 month; plant pointed end up by cuttings: ??Plant/seed sources (see list for source numbers): 8, 13, 14, 16 4/30/13 Project SOUND 3. * Canyon Gooseberry Ribes menziesii (RYE-bees men-ZEE-see-eye )Family: Grossulaceae (Gooseberry Family)Native to: Central & North Coast of CA to OR as well as western Sierra foothills; several differentvarieties grow from moist or marshy areas to drier hillsides, coastal canyons and foothills inRedwood Forest, Mixed Evergreen Forest, Chaparral between 0 and 3500 feet.Growth characteristics: woody shrub mature height: 4-8+ ft. mature width: 5-7 ft.Open, many-branched shrub with arching branches. Branches very prickly (typical of gooseberries).Leaves medium green, rounded, aromatic and velvety with glandular hairs. Very attractive growthhabit; slightly more open/graceful than our local Fuschia-flowered Gooseberry (Ribes speciosum).Will drop leaves in hot summer/fall conditions.Blooms/fruits: Blooms late winter/early spring (Feb. to April depending on weather). Flowers alsosimilar to Ribes speciosum: sepals are fuchsia or purple, petals are white and extend forward to forma loose tube from which the stamens emerge. Flowers dangle from branches and resemble tinyfuschia flowers; truly spectacular in bloom. Spiny dark fruits ripen in summer; edible.Uses in the garden: Mostly used as an ornamental shrub because of its flowers. Also popular in birdand butterfly habitat gardens attract hummingbirds and fruit-eaters. Spines make this a goodchoice for a barrier or hedge. Fine under oaks. Beautiful and unique plant just plant it back farenough that you dont brush against it. Native Californians cooked and dried berries for food.Sensible substitute for: Non-native gooseberries.Attracts: Excellent bird & butterfly habitat: provides cover, nectar and fruits for food. Alsoprovides cover for small creatures like lizards.Requirements:Element RequirementSun Part-shade (morning sun fine) or dappled sun.Soil Well-drained soils best; any local pH.Water Best with occasional summer water Water Zone 1-2 or 2. Dont water on hot daysor get water on leaves/trunk.Fertilizer Not needed; low doses likely fine.Other Likes an organic mulch.Management: Prune out old, dead branches when dormant in fall. Be careful not to over-water insummer; consider locating this plant near an area that gets fairly regular water.Propagation: from seed: dried seed needs 2-3 month cold treatment by cuttings: yesPlant/seed sources (see list for source numbers): 6, 8, 13 4/29/13 Project SOUND 4. * Fendlers Meadowrue Thalictrum fendleri var. polycarpum(Thal-IK-trum FEND-ler-eye poly-CAR-pum )Family: Ranunculaceae (Buttercup Family)Native to: Western N. America from Baja, NV/UT to OR. In forested areas including the SantaMonica/San Gabriel Mtns; moist, open/shaded places in forests, along streams usually < 5000 ft.Growth characteristics: herbaceous perennial mature height: 2-4 ft. mature width: 2-3 ft.Drought-deciduous herbaceous perennial that dies back to the root in dry summer conditions.Foliage primarily in basal rosette. Leaves bright green, much divided with rounded leaflets. Plantlooks fern- or columbine-like. Pretty and unusual. Plants do have a strange odor smell beforeyou purchase. Note: stems and roots may be poisonous if eaten.Blooms/fruits: Blooms in mid- to late spring usually Aril-June in local gardens. Plants aredioecious (separate male & female plants); male flowers are the showy ones, so most plants sold bynurseries are male. Male flowers in clusters on drooping stalks very unusual and showy (in a quietway). Flower color: green or white with pink-purple (see photo).Uses in the garden: Most often used as a perennial for shady areas of the garden. Lovely additionto the woodland garden, with native ferns, grasses, Heuchera. Fine under oaks and other largetrees. Should do fine in a large container or in a shady flower bed. Plant where you can enjoy theunusual flowers (near seating; along a shady walkway). More showy when massed. NativeCalifornians used an infusion externally for pain.Sensible substitute for: Non-native perennials.Requirements:Element RequirementSun Part-shade to quite shady in our area.Soil Any texture sandy to clay; any local pH.Water Needs moist soil until after flowering; then does fine at Water Zone 2 or 1-2 (veryoccasional summer water)Fertilizer Loves a leaf litter mulch; would accept low doses of fertilizer.Other Leaf or other organic mulch.Management: Prune out dead foliage in late summer after seeds have spread.Propagation: from seed: fresh seed no pre-treatment by divisions: in springPlant/seed sources (see list for source numbers): 1, 3, 5, 8, 10-14, 19, 20, 25 4/29/13 Project SOUND 5. Catalina Nightshade Solanum wallacei (so-LAN-um wah-LASS-ee-eye)Family: Solanaceae (Nightshade Family)Native to: Channel Islands of S. CA and Baja; uncommon on slopes and canyons in chaparral
