J20170907-0002—Baccharis pilularis Al's Blue—RPBG by John Rusk Via Flickr: Baccharis pilularis "Al's Blue"—coyote brush. A dominant species in the northern California coastal scrub, less so, in Southern California. This is the upright form often known as the subspecies consanguinea that many, but not all, references ( including The Jepson Manual, 2nd ed. and Flora of North America) recognize . This upright form can be shaped into hedges in gardens. The selection "Al's Blue" is named for Al Seneres, a now-retired garden supervisor at Regional Parks Botanic Garden. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.

Widespread throughout western North America from Canada to Mexico, this highly variable species is found in disturbed areas from 300 meters elevation to 2750 meters. The insect is a bee of the genus Hylaeus. It is quite common to find bees and other insects visiting these plants.

J20171005-0026—Ericameria fasciculata—RPBG—DxO by John Rusk Via Flickr: Ericameria fasciculata—Eastwood's goldenbush. The species is included in the CNPS Inventory of Rare and Endangered Plants on list 1B.1 (rare, threatened, or endangered in CA and elsewhere). Eastwood's goldenbush is presently found solely in Northern Monterey County. Although much habitat is protected in Fort Ord National Monument, S.F.B. Morse Botanical Preserve, and Monterey County parks, the species is sometimes inadvertently sprayed in weed abatement programs because it colonizes disturbed areas. An excellent description of the plant can be found in Elkhorn Slough Coastal Training Program fact sheet "Ericameria fasciculata" www.elkhornsloughctp.org/factsheet/factsheet.php?SPECIES_... .

J20171012-0023—Ericameria cuneata—RPBG—DxO by John Rusk Via Flickr: Ericameria cuneata—rock goldenbush. Grows along both slopes of the Sierra Nevada from Sierra County southward, the Transverse Ranges, the Desert Mountains, the Peninsular Ranges into Baja California, and Eastward to Nevada and New Mexico. In habitat, it is almost always found in fissures in granite outcrops. This late-season bloomer is, thus, a good plant for rock gardens and between slabs in garden walls made of native stone.

J20170824-0072—Solidago velutina ssp californica—RPBG—DxO by John Rusk Via Flickr: Solidago velutina ssp. californica—California goldenrod. Familiar to most as just Solidago californica, this goldenrod was moved to S. velutina ssp. californica in The Jepson Manual (2nd ed.) A favorite of bees, butterflies, and other insects during late summer and autumn. This Solidago is found throughout most of California except for the deserts. Its range extends to Oregon on the north and Baja California to the south. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.

J20171019-0019—Ericameria palmeri var palmeri—RPBG—DxO by John Rusk Via Flickr: Ericameria palmeri var. palmeri— Palmer's goldenbush. Included in the CNPS Inventory of Rare and Endangered Plants on list 1B.1 (rare, threatened, or endangered in CA and elsewhere). The tag gives the location as Otay Mountain, that refugium for rare species in San Diego County. Luckily, the plant is not quite as rare in Baja California, but even there it is threatened by development. The CNPS Inventory says there are 16 small populations north of the border. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.

J20171026-0009—Grindelia stricta var platyphylla—RPBG—DxO by John Rusk Via Flickr: Grindelia stricta var. platyphylla—Pacific gum plant. The Flora of North America has lumped this taxon into Grindelia hirsutula. The Jepson E-Flora as well as PLANTS database retain G. stricta var. platyphylla. Found in salt marshes along the coastal strand from Del Norte County south to Ventura County, including the northern Channel Islands. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.

J20170810-0003—Ericameria nauseosa (syn Chrysothamnus nauseosus )—RPBG—DxO by John Rusk Via Flickr: Ericameria nauseosa—rubber rabbitbrush. Formerly Chrysothamnus nauseosus, the species was transferred to Ericameria in the 1990s. The species is widespread through the American west and northwestern Mexico. The "rubber" part of its common name comes from the latex exuded from the plant. It was studied as a source of rubber during both the twentieth-century world wars and still is regarded as a potential source of a type of rubber.

E20170831-0001—Hazardia detonsa—RPBG by John Rusk Via Flickr: Hazardia detonsa—Island bristleweed. Endemic to the northern Channel Islands. The removal of feral goats from the islands has led to the recovery of the species. The plant the provided the leaves photographed resides at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA . Leaves on the left show the reverse (back) side while leaves on the right show the obverse (front) side.

J20171130-0001—Erigeron glaucus—RPBG by John Rusk Via Flickr: Erigeron glaucus—seaside daisy. Grows along coastal bluffs and shoreline from Oregon to Santa Barbara and the northern Channel Islands. It is a perennial that spreads by both rhizomes and seeds. Color of the ray flowers vary from white to lavender and darker. The large expanse of disk flowers are always yellowish. One could probably take a picture in our garden of this species' flowers any week of the year. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.
