If you've never been to a UC Davis Arboretum plant sale, you should.
The last plant sale of the year will take place Sunday, Oct. 14 from 9 a.m. to 1 p.m. at the Arboretum Teaching Nursery on Garrod Drive.
If you're looking for plants that will attract bees, or plants that will attract butterflies, or plants that will attract both, experienced gardeners there can help you. Check out their inventory.
Nearby is the Nature's Gallery Court Mural, showcasing plants found in the Storer Garden and the insects that gravitate toward them. The mural is the work of the UC Davis Art/ Science Fusion Program, co-founded and co-directed by entomologist/artist Diane Ullman and artist Donna Billick.
If you take a stroll through the nearby Storer Garden, you'll see such plants as white flowering quince (Chaenomeles speciosa "Contorta"), cenizio (Leucophyllum frutescens) and winter jasmine (Jasminum nudiflorum).
The honey bees love 'em.

It's raining rain lilies in the Carolee Shields White Flower Garden of the UC Davis Arboretum.
The Argentine Rain Lily (Zephyranthes candida), also known as the White Rain Lily, White Fairy Lily and White Zephyr Lily, is drawing a few honey bees, but the bees like the lavender and sage best.
The white Zeph is one of the "Arboretum All-Stars," a list of 100 plants that thrive in the Central Valley and stay attractive most of the year. Most of the All-Stars are also drought tolerant, require little maintenance, and are relatively pest free, Arboretum officials say. A few--about 15--are California natives.
You can find the All-Stars (and other plants) at the Arboretum's periodic plant sales; the next sales are Oct. 3 and Oct. 17.
"Bee there" for bee-friendly plants and other selections.
At the last sale, we picked up some sage and a carnivorous plant.
To be honest, we were happy the carnivorous plant died. It ate one of our honey bees.
The UC Davis Arboretum has been working to develop a list of plants that are specifically chosen for the Central Valley. This list, called the “Arboretum All-Stars,” has been developed over many years using the Arboretum and other research sites to test and trial plant species. The official “roll out” of the program is planned for spring 2009, but the plant species list and other information is available now at http://arboretum.ucdavis.edu. In addition to creating the list, the program plans to encourage wholesale nurseries to grow these plants in large enough quantity to supply an interested public, and to educate the public to look and ask for these species.
All of the 100 plants on the list had to meet the following criteria: they must be attractive most of the year, thrive in Central Valley conditions, and have been tested at the UC Davis Arboretum. Many of them are also drought tolerant, require little maintenance and can reduce use of pesticides by being relatively pest-free and by attracting beneficial wildlife that feed on pests before they become a problem. About 15 of the species are California native plants.

If you stuff your turkey with sage, chances are it's Salvia officinalis.
Not the turkey, the sage.
And if you visit the Storer Garden at the UC Davis Arboretum, you'll see bumble bees stuffing themselves with nectar from the purple flowers of Salvia officinalis, cultivar Berggarten, also known as Berggarten sage.
Scores of Bombus californicus nectared the flowers last weekend, seemingly proving that this is indeed a culinary sage favored by people AND bumble bees.
Salvia officinalis (salvia is Latin for "to heal") shows up in both medicinal and culinary history. In fact, Wikipedia says our ancestors used it to ward off evil and snakebites, to increase women's fertility, "and more."
The "and more" means just that. Think of every ailment known to humankind. Now fast forward to modern times. Some researchers are using it to treat mild-to-moderate Alzheimer's disease and depression.
On the culinary side, Julia Child favored it as a flavorful herb.
Bombus californicus probably knows something that Julia Child did.

The Smithsonian Institution is the place to "bee" on Monday, June 22.
UC Davis pollinator specialist and researcher Robbin Thorp will join other bumble bee experts from across the country in a "Plight of the Bumble Bees" public symposium from 10 a.m. to 12:30
The location: Baird Auditorium, National Museum of Natural History. The Smithsonian is located at the corner of 10th Street and Constitution Avenue NW, Washington D.C.
Thorp will discuss "Western Bumble Bees in Peril." Sydney Cameron and Jeff Lozier of the University of Illinois will examine "The Status and Trends of Midwestern and Southern Bumble Bees." Then Leif Richardson of the Vermont Department of Fish and Wildlife will cover "Bumble Bee Trends in Northeastern North America."
Other speakers:
- Stephen Buchmann, University of Arizona, "USA Native Bee Diversity: Rarity, Threats and Conservation Ideals"
- Paul Williams, Natural History Museum, London, "A Global View of Bumble Bees and Their Conservation Status."
Michael Ruggiero of the Smithsonian Institution will moderate. He's the senior science advisor of the Smithsonian's Integrated Taxonomic System (ITIS).
Following the symposium, bumble bee experts and other scientists will continue to meet at the Smithsonian for the next two and a half days to discuss concerns about the declining bumble bee population.
The symposium is part of National Pollinator Week, which starts Monday, June 22 and continues through Sunday, June 28.
Thorp delivered a presentation on Franklin's bumble bee May 27, during one of the UC Davis Department of Entomology's noonhour sessions. Franklin's bumble bee, feared extinct or nearing extinction, is found only in one part of the world: southern Oregon and northern California. Thorp's talk was Webcast.
Thorp, a member of the California Academy of Sciences since 1986, says that the loss of a native pollinator "could strike a devasting blow to the ecosystem, economy and food supply."
Locally, we've noticed far fewer bumble bees than in past years. Last summer we spotted a few in the UC Davis Arboretum (see below). This is the yellow-faced bumble bee or Bombus vosnesenskii, the most common Califonria bumble bee.
Not so common any more.

If you like to take nature walks and lean against an occasional tree, you might rub shoulders with a red-eyed, red-shouldered bug.
On warm, springlike days, soapberry bugs are exploring their territories--and doing what comes naturally.
These predominately black-and-red bugs are seed feeders on plants but they're much more than that. Scientists consider them the evolutionary “canary in the coal mine.”
I captured these photos of soapberry bugs last Friday in the UC Davis Arboretum. UC Davis biologist Scott Carroll, biologist who studies basic and applied aspects of evolutionary biology, specifically soapberry bugs, considers them "good mothers and avid lovers." .
“Soapberry bugs are tame, pretty, good mothers, avid lovers, and among the best native guides to ongoing evolution on the planet," he writes on his under-construction Web site.
"They respond quicky to changes in the environment and can be good models for observing evolution in action."
They're also good photographic models.
