The range of B. laciniata extends southward from San Diego County to the Central Desert in Baja California. It has been used in restoration projects as far north as the San Francisco Bay Area to the displeasure of some restoration ecologists.

A hardy perennial suited for informal gardens. S. chilense requires almost no summer water once estabished. The color of the ray flowers can vary from deep purple to nearly pure white.

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_... .

J20161110-0095—Munzothamnus blairii—RPBG—DxO by John Rusk Via Flickr: Munzothamnus blairii—Blair's wirelettuce. The species is included in the CNPS Inventory of Rare and Endangered Plants on list 1B.2 (rare, threatened, or endangered in CA and elsewhere). Once a candidate for extinction, the species prospects are brighter now that feral goats have been removed from San Clemente Island, the only place the wirelettuce grows. M. blairii was once placed in the genus Stephanomeria but both morphological and DNA analysis show that the species deserves a genus of its own. Those interested in such matters should read the Flora of North America treatment of the species. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.

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.

Included in the CNPS Inventory of Rare and Endangered Plants on list 1B.1 (rare, threatened, or endangered in CA and elsewhere).
