You'll see drought-tolerant plants, plants perfect for your pollinators, and the Arboretum All-Stars. The All-Stars are the Oscars of your garden. They're like Academy Awards. The horticultural staff selected some 100 plants that are "easy to grow, don't need a lot of water, have few problems with pests or diseases, and have outstanding qualities in the garden. Many of them are California native plants and support native birds and insects. Most All-Star plants can be successfully planted and grown throughout California."
The teaching nursery is stocked with more than 14,000 plants of almost 400 varieties. Eighty-percent were grown on site. (Download this PDF to access the inventory.)
It's a members' only sale, but anyone can become a member at the door. The staff asks that you BYOC or BYOB. That's Bring Your Own Cart or Bring Your Own Box. A limited number of carts is available.
While there, be sure to check out the permanent garden art that graces the teaching nursery. You'll see artistic bugs created by UC Davis students under the tutelage, encouragement and inspiration of the Ullman/Billick duo. That would be entomologist/artist Diane Ullman, professor of entomology at UC Davis, and self-described "rock artist" Donna Billick (who has a bachelor's degree in genetics). They co-founded and co-directed the UC Davis Art/Science Fusion Program. The resulting ceramic-mosaic art is a treasure trove, not only in the Arboretum teaching nursery, but throughout the campus and downtown Davis and beyond. It's a living legacy of what can be done when art is fused with science, and when science is fused with art.

How's your front yard looking?
A little bit brown due to the drought? Thinking of replacing some of your plants with drought-tolerant ones? And hoping to attract some bees, butterflies and other wildlife?
You're in luck. The UC Davis Arboretum is planning its next public plant sale this Saturday, Oct. 11. The theme is, appropriately enough, "The New Front Yard."
The plant sale will take place in the UC Davis Arboretum Teaching Nursery on Garrod Drive. It's open to members only from 9 to 11 a.m. (but if you're not a member, you can join at the door), and it's open to the general public from 11 a.m. to 1 p.m.
UC Davis Arboretum officials point out that many homeowners want to replace "high-water use plants with low-water alternatives" and they're going to help you. "We are going to have the area's largest selection of attractive, drought-tolerant, easy-care, region-appropriate plants including lots of California natives and Arboretum All-Stars."
They've published a list of some "attractive, region-appropriate plants that save water and support wildlife," complete with botanical names and photos. (Download PDF)
They include California buckeye, manzanitas, California pipevine, narrow leaf milkweed, Frikart's aster, Caliifornia aster, coyote brush, creeping Oregon grape, Blonde ambition blue grama grass, western spicebush, concha Ceanothus, Ray Hartman's California lilac, western red bud, Island mountain mahogany, California fuchsia, California buckwheat, St. Catherine's lace, coast silktassel, salt heliotrope, toyon, purple lantana, Goodwin Creek lavender, cape weed, monkey flower, deergrass, Hopley's purple oregano, Santa Margarita foothill penstemon, hollyleaf cherry, blue oak, California coffeeberry, pink chaparral currant, flowering currant, Santa Catalina Island currant, white sage, Cleveland sage, autumn sage, Santa Barbara sage, Cascade Creek California goldenrod, alkali sacaton, yellow autumn crocus and Roger's red grape.
Those are just a few of the plants they're offering for the plant sale.
Ah, so many choices, so little space. And one of the best parts? The bees and butterflies and other pollinators they attract.

Are you on a winning streak? Or a losing streak? Or somewhere in between?
The Gray Hairstreak butterfly (Strymon melinus) is always on a streak--a gray streak.
Butterfly expert Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, writes about the Gray Hairstreak on his website, Art's Butterfly World. It's one of the many butterflies in the Central Valley that he's monitored over the past four decades.
It's most common in weedy and disturbed habitats at low elevation, Shapiro says, adding that it's "territorial and a hilltopper in suitable terrain, but does very well in towns and cities in the Central Valley. It is multiple-brooded and has a very long flight season, at sea level from February to November, but rarely seen before June in the mountains where it does not appear able to overwinter."
"Its most frequent hosts in our area are mallows, including the weedy species of Malva; legumes, including Spanish Lotus (Lotus purshianus), bird's-boot trefoil (Lotus corniculatus), white clover (Trifolium repens) in lawns, alfalfa (Medicago sativa) and many others;and turkey mullein (Eremocarpus or Croton setigerus, Euphorbiaceae)."
We recently spotted the Gray Hairstreak grabbing some nectar on our guara (Guara lindheimer). Its distinctive orange spot matched perfectly the color of the nearby Mexican sunflower (Tithonia).
Those of us joining naturalist Steve Daubert's butterfly talk and tour at the UC Davis Arboretum last September also spotted a Gray Hairstreak. The good news is that he's giving another "Butterfly Ecology Talk and Walk," sponsored by the UC Davis Arboretum, on Sunday, Sept. 14. It's free and open to the public. Participants will gather at 11 a.m. by the trellis at the California Native Plant GATEway Garden (newly-constructed garden at the Arboretum's east end, just behind the Davis Commons Shopping Center). (See the Arboretum calendar for more information and a map.)
"Last year at the Arboretum Butterfly Walk and Talk we talked about the co-evolution of the butterflies with the flowering plants, starting in the Middle Cretaceous," Daubert told us in an email. "This year we will set the scene farther back into the Mesozoic Era and talk about the origin of the advanced insect orders, including the Lepidoptera (the holometabolous insects). We will also talk about blue colors in the animals. And we will talk about butterfly gardening for folks here in the valley. We will be looking to see members of the five butterfly families commonly found in Davis."
Daubert is a molecular scientist in the UC Davis Department of Plant Pathology. In addition to writing scientific technical text, he writes short stories, illustrated with his own photographs. He blogs at threadsintheweb.com.

If you're thinking about adding more bee friendly plants to your garden but you're concerned about the drought, the UC Davis Arboretum has the answers.
The arboretum will host its public spring clearance plant sale on Saturday, May 17, from 9 a.m. to 1 p.m. at the UC Davis Arboretum Teaching Nursery on Garrod Drive.
You'll find a large election of Christmas natives and Arboretum All-Stars. (Members of the Friends of the UC Davis Arboretum and the Davis Botanical Society receive 10 percent off their purchases. And yes, you can join the Friends on May 17.)
One of the plants we like--as do the birds and the bees--is Kniphofia "Christmas Cheer," also known as a red hot poker and torch lily. Ellen Zagory, horticulture director of the Arboretum, describes it as "a torch lily on steriods. It gets big and puts out a large display of showy flowers in winter and long into spring."
Yes, it does.
We remember taking a photo of the Christmas Cheer on Christmas Day in the Arboretum's Storer Garden. The bees didn't know about the winter break. Neither did a finch.
Break? What break?
In a recent newsletter, Zagory wrote about some of the plants that will be available for sale.
“On campus we have fairly heavy soil and water that's high in bicarbonates and boron, so I always think…if it grows well here, it will do even better elsewhere. In light of limited water supplies and rising water prices we need to think even harder about plants that can survive with low or very low quantities of water, but they can still be pretty. You'd never know these were drought-tolerant considering the seasonal impact and drama they provide!”
The Arboretum kindly provides a list of available plants that you can download from its web page.
The bees--and the birds, butterflies and others engaged in animal/plant interactions--will thank you.

When it ought to be raining, it's raining pink.
They say you can't fool Mother Nature or outsmart Father Time but that's not the case in the UC Davis Arboretum. A red Japanese apricot, Prunus mume "Matsubara red" glows with absolute radiance in the Storer Garden. It's a early bloomer, but this year it's really early due to the springlike temperatures.
We first noticed it blooming Jan. 5. It's still blooming, and honey bees--probably from the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road--are all over it.
The flowering apricot bears the name "red Japanese apricot," but its origin is China and Korea. It's been cultivated in Asia for some 500 years.
If you've never been to the Storer Garden, you should go. As it says on the Arboretum website: "The Ruth Risdon Storer Garden is a Valley-wise garden, featuring flowering perennials and small shrubs that are especially well suited to Central Valley gardens, including many Arboretum All-Stars, our recommended plants for Valley-wise gardens. It is designed for year-round color with low water use and low maintenance, and features a demonstration planting of roses and companion plants. Educational exhibits highlight the principles of sustainable gardening. The garden is named for Dr. Ruth Storer, Yolo County’s first pediatrician and an avid gardener."
For most of January, it's been raining pink in the Storer Garden. Now we need the wet stuff.
