When you attend the UC Davis Biodiversity Museum Day on Saturday, Feb. 15, you'll see these California natives blooming in the Biological Orchard and Gardens (BOG), a 24,000-square-foot treasure behind the UC Davis Botanical Conservatory off Kleiber Hall Drive.
The ninth annual Biodiversity Museum Day, a science-based day that's free and family friendly, will take place from 9 a.m. to 4 p.m. and showcase 13 museums or collections, including the Botanical Conservatory, managed by curator Ernesto Sandoval.
BOG is a living museum, planted not only with several dozen species of heritage fruit trees, but landscaped with colorful mini-gardens.
Among the flowers blooming in the BOG in the early spring, by color:
- Red: European red flax, Linum grandiflorum rubrum, an annual that's native to Algeria
- Yellow: tidy tips, Layia platyglossa, an annual that's native to California
--The seep monkey flower, Mimulus guttatus, native to California
--Lupine, Lupinus, native to North America.
- Blue: Desert bell, Phacelia campanularia, an annual herb that is native to California and endemic (limited) to California.
- Lavender: Phacelia, also called Lacy phacelia, blue tansy or purple tansy (Phacelia tanacetifolia), native to the southwestern United States
--Lupine: Lupinus, native to North America
- Red-Orange-Yellow: Blanket flower or Gaillardia (Gaillardia × grandiflora), native to North and South America
- Orange: California golden poppies, Eschscholtzia californica
The orchard contains heritage fruit tree varieties threatened with commercial extinction. They include the Gravenstein and Johnathan apples; the Suncrest peach; the Bleinheim apricot, the Mariposa plum and the Meyer lemon.

UC Davis Biodiversity Museum Day
The ninth annual UC Davis Biodiversity Museum Day is billed as a “free, educational event for the community where visitors get to meet and talk with UC Davis scientists from undergraduate students to staff to emeritus professors and see amazing objects and organisms from the world around us,” according to Biodiversity Museum Day coordinator Tabatha Yang, education and outreach coordinator for the Bohart Museum of Entomology. Last year's event drew more than 4000 visitors. The event is always held the Saturday of Presidents' Day weekend.
The schedule is online at http://biodiversitymuseumday.ucdavis.edu/schedule.html.

Talk about pollen!
The bumble bees, Bombus vandykei (as identified by Robbin Thorp, distinguished emeritus professor of entomology at the University of California, Davis), were buzzing all over the Phacelia last week on the central campus.
One bumble bee carried a heavy load of orange pollen (collected nearby), while another, a small load of blue pollen. They both wanted the same flower.
I'll have what you're having! Move, please.
Sorry. I'm not finished here.
She didn't move. Not then.
Both the bumble bee and the plant are natives.
The genus Phacelia, also known by its common name, phacelia, or scorpionweed or heliotrope, is native to North and South America. Its genus includes some 200 species.
VanDyke's Bumble Bee is found in the Pacific Coastal states, including Washington, Oregon and California. Bombus vandykei is one of about 250 described species of bumble bees worldwide. All belong to the genus, Bombus.
The vandykei males are extensively blond, but not the females. In fact, the females are often confused with the yellow-faced bumble bee, Bombus vosnesenskii. (A distinguishing feature: on the vandykei, the yellow abdominal band is on T3 rather than T4.) See BugGuide.Net.
Want to know more about bumble bees and how to identify them? Be sure to pick up a copy of Bumble Bees of North America: An Identification Guide (Princeton University Press), co-authored by Thorp and fellow scientists Paul Williams, Leif Richardson and Sheila Colla. It won a 2015 Outstanding Reference Sources Award, Reference and User Services Association, American Library Association.
A really innovative touch to the Princeton University site is the buzz. Click on the link, http://press.princeton.edu/titles/10219.html, and you'll hear the buzz.
It's just like being in a Phacelia patch filled with bumble bees!
The first thing you notice when you walk up to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, UC Davis, are the natives.
Native plants, that is.
California golden poppies and phacelia are among the plants sharing the "Pollination Habitat" bed. The golden poppies literally light up the landscape. The phacelia, not so much.
The next thing you notice are the bumble bees, carpenter bees, honey bees and syrphid flies foraging on the natives. An occasional butterfly flits by.
Today a bumble bee, Bombus vandykei, buzzed from one phacelia to another. She was interested only in phacelia. Nothing else, thank you.
She quickly found herself competing with honey bees for the nectar and pollen.
A sign, "Pollinator Habitat," tells the story:
"This area has been placed with a range of flowering native plants to provide hgh waulity habitat for native bees and other pollinators. To learn how you can create good habitat for pollinators please visit www.xerces.org."
Phacelia is one of the bee plants recommended in G. H.Vansell's booklet, Nectar and Pollen Plants of California (Bulletin 517). Extension apiculturist Eric Mussen of the UC Davis Department of Entomology, mentions phacelia in his list of good bee plants in a 2002 edition of his newsletter, from the UC apiaries.
And phacelia is also a plant that pollination ecologist Neal Williams, assistant professor of entomology at UC Davis, is studying.
