J20161013-0046—Bahiopsis laciniata—RPBG—DxO by John Rusk Via Flickr: Bahiopsis laciniata—San Diego County viguiera. Formerly known as Viguiera lacinata. 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. Las Pilitas Nursery say the plant flowers nearly year around, an observation confirmed by the experience of Regional Parks Botanic Garden.

J20160623-0092—Ipomopsis tenuifolia—RPBG by John Rusk Via Flickr: Ipomopsis tenuifolia—Slenderleaf skyrocket. The species is included in the CNPS Inventory of Rare and Endangered Plants on list 2B.3 (rare, threatened, or endangered in CA; common elsewhere). It has a California State Rank of S2. There are just a small number of populations in San Diego and Imperial counties not far north of the border. Luckily, the plant is much wider spread in northern Baja California. The exserted stamens and style help identify this species. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.

J20161006-0017—Acer macrophyllum—RPBG by John Rusk Via Flickr: Acer macrophyllum—bigleaf maple. California does not possess the large areas of hardwood forests that cover much of the eastern United States. Displays of fall colors are localized and limited for the most part to understory shrubs and trees. There are, of course, the glorious aspens as well as several species of maples. Bigleaf maple is simply glorious when the sun backlights the leaves. Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.

E20161004-0001—Calliandra californica by John Rusk Via Flickr: Calliandra californica—Baja fairy duster. This plant, a native of Baja California, barely makes it into the California Floristic Province. I have another photo of the species in habitat at a location that must be near the southern border of the province. This specimen has been growing in a sunny, well-protected spot on the west side of our home since the late 1990s. It blooms every year. Photographed at a private garden in Berkeley, CA

The name "chilense" is a misnomer as it it not a Chile native but it found in many plant communities along the Pacific coast from British Columbia to Santa Barbara and Ventura counties in California. 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.

American Indians used a concoction as a disinfectant. They also used the leaves as food. Those interested in herbal uses should Google the species. The species grows in coastal California as well as the Transverse and Peninsular Ranges north from San Diego County into Southwestern Oregon. It is also found in the northern Sierra Nevada.

H20120920-5647—Asclepias speciosa—RPBG by John Rusk Via Flickr: Asclepias speciosa—showy milkweed. The species has gained fame in recent years as an important larval plant for west coast monarch butterflies. Many weed manuals cite plants of the genus Asclepias as poisonous to livestock and even humans. It is, however, easy to find ethnobotanical references as well as recipes promoting the consumption of milkweeds.Photographed at Regional Parks Botanic Garden located in Tilden Regional Park near Berkeley, CA.

J20170511-0019—Rhododendron occidentale—RPBG—DxO by John Rusk Via Flickr: Rhododendron occidentale—western azalea. Grows from southern Oregon in the Coast Ranges and Sierra Nevada as far south as Monterey and Kern Counties, with disjunct populations in Riverside and San Diego Counties. Introduced into Great Britain by 1850, the western azalea became an important contributor to the gene pool the created the modern hybrid ornamental azalea. Sheepmen detest the western azalea because its leaves are sheep killers.. The California Poison Control System rates the toxicity as "Major." Rhododendrons, in general, are also said to be a source of "mad honey," a malady that exists more in folklore than in reality.

P20130705-0043—Lilium humboldtii ssp ocellatum—RPBG by John Rusk Via Flickr: Lilium humboldtii ssp. ocellatum—spotted Humboldt's lily. Included in the CNPS Inventory of Rare and Endangered Plants on list 4.2 (limited distribution). To quote the late Bert Wilson of Las Pilitas Nursery at length: "This subspecies is native from Northern Santa Barbara County south into San Diego County. Commonly growing in canyons or on north slopes. A very showy and attractive lily, a somewhat drought tolerant lily. The lilies are divided into wetland species and dry land species. This is more of a dryland species. Our experience is it likes garden conditions with part sun. Bambi and her chipmunk friends will eat this one. Extremely beautiful and long-lived The plant can have a hundred flowers on it and be two meters high and one wide, if conditions are to its liking and if you can keep the gophers away. In some gardens the flowers may reach the eves of the house". Photographed at Regional Parks Botanic Garden Located in Tilden Regional Park near Berkeley, CA.
