This summer I have had the joy of being an intern at the Honey Bee Haven. It seems quite unfair that many students were taking summer classes or holed up in labs while I got to be outside working in a beautiful garden!
If you have visited the garden recently, you will have noticed the multitude of new plants signs. Updating the signs has been a summer-long project that started during my first week at the Haven. Back in June, Chris showed me around the garden and had me take notes on what plant signs we needed to add to the garden. I come from a botanical background, so I thought I knew plants, yet I found myself having trouble connecting the plants in the garden to the plant names I recognized.
In the following weeks, I worked with and among the garden's 250-plus plants, I researched the best bee-friendly plant families, and I drew and painted dozens of flowers for Haven displays. The time flew by and soon enough it was the end of September - time to finish updating and replacing the plant labels. By then, I could easily recognized most of the plant families and individual species. As Chris and I placed signs throughout the garden, I was also reminded of the things I had seen and done throughout the summer. The shasta daisies, yarrows, california buckwheat, and gum plant had become my constant companions through the our survey of natural enemies; the catmint, calamint, and cape balsam were buzzing with honeybees as they had been all summer; and the zinnias were busier than ever with visits from honeybees, native bees, skipper butterflies, and gulf fritillary butterflies.
While I will take away many things from this experience – a special fondness for mantids, an appreciation for combining art and science, and a much greater knowledge of plant and bee biology – my greatest take away will be the genuine interest and excitement of the people that I met in the garden. All garden guests, energetic children to master gardeners, were always happy to learn something new and share their garden experience. The garden is a wonderful place to let your imagination run wild whether you're seeking out cool critters or new garden ideas.
Overall, I have come to realize that, to be a good gardener you have to understand and appreciate insects, and to be a good entomologist you have to understand and appreciate plants. So being a gardening entomologist certainly has its advantages!

Thanks to all who made the final Honey Bee Haven open house of 2014 a success! Visitors had the chance to view pinned specimens and live bees in the garden, as well as in the observation honey bee hive. Several folks purchased bee houses, and three lucky raffle winners went home with plants or a copy of the newly published California Bees and Blooms.
From the UC Davis Department of Entomology and Nematology, thanks go to bee biologists Bernardo Nino, Elina Nino, and Billy Synk, administrative staffer Maria Tuccori, and garden intern Kirsten Pearsons. Garden volunteers who helped include Emily Kultgen, Stephanie Macey-Gallow, and Kelly McKee.

Here at the Haven we're all about providing ideas to make bee gardening easy. We just want you to do it! One simple way to create a bee garden is to plant an herb garden. Not only will you help the bees, you'll have fresh herbs for cooking the food that bee pollination has provided. Let your herbs flower and you're all set; cut the flowers off as they fade to ensure repeat bloom. An added benefit is that many common Mediterranean-climate herbs are fairly low water users.
While herbs generally bloom in the summer and early fall, rosemary and borage bloom in the winter and early spring, respectively. Include these in your bee herb garden to maximize the resources you are providing. Herbs currently flowering at the Haven include basil, oregano, catnip, calamint, and rosemary.

Fall is the best time of year to plant. Warm days, cool nights, and an upcoming winter of rain (we hope!) help ensure good plant establishment. When planning your bee garden, remember the following:
- Vary flower shape, size, and color
- Plant for year-round bloom
- Include a variety of plant families
- Plant in drifts
- Native plants for native bees
- Provide a water source
- Leave some bare, unmulched soil
- Add nesting blocks

Everyone can appreciate the beauty of flowers, but that's not to say flowers look nice just for us! We often get asked by Haven visitors how bees find their flower hosts. One way is through unique flower colors and shapes. Once bees are near a plant, flowers with intricate patterns can entice them even further through patterns on the petals that direct bees straight towards nectar rewards. Like runway lights at the airport, these intricate nectar guides can help orient pollinators during their flower visits.
Nectar guides are doubly useful for bees, as they use guides at individual flowers to find nectar faster and as search images to target similar flowers. Since plants of the same species tend to be flowering at the same time, loyal bees can be more efficient than bees that hop from one species to another. It's a win-win situation since loyal bees can collect nectar with less effort and the flowers get a greater chance of receiving pollen from their own species (Functional Ecology 2011, 24, 1293-1301).
So what about simple monotone flowers? Well, the thing about nectar guides is that we humans can't always see what the bees do! We can see all of the colors from red to violet, but bees see a shifted spectrum from yellow through ultra-violet (UV). So to bees, even seemingly plain flowers may have bold nectar guide patterns. With UV sensors, even humans can get a glimpse of what nectar guides look like to bees. (Plant Species Biology 2013, 28, 177-184). The web site Flowers in Ultra-Violet has many images comparing flowers in daylight and UV light in which the guides are visible.
Other than bees, hummingbirds, hawkmoths, and syrphid flies have been found to respond to nectar guides. Some flowers even have overlapping visible nectar guides and UV nectar guides, possibly to attract birds and bees simultaneously. (Functional Ecology 2011, 24, 1293-1301).
As you walk through the Haven, look at our flowers for these intricate patterns. Here are two of the species in our garden with visible nectar guides:
