Your water-efficient landscape doesn’t have to be barren
UC climate-ready landscape trials identify low-water yet attractive plants
Good news: roses can be a part of your water-efficient landscape. Lorence Oki, UC Cooperative Extension environmental horticulture specialist in the UC Davis Department of Plant Sciences, identified rose cultivars that remain aesthetically pleasing with little water.
Oki is the principal investigator of the Climate-Ready Landscape Plants project, which may be the largest irrigation trial in the western U.S., and the UC Plant Landscape Irrigation Trials (UCLPIT), the California component of that project. These projects evaluate landscape plants under varying irrigation levels to determine their optimal performance in regions requiring supplemental summer water.
“There are some assumptions that pretty plants use a lot of water, like roses,” Oki said. “Everyone thinks they need a lot of water, but we've found some that don't, and they still look great. A water-efficient landscape doesn't need to look like a Central Valley oak-grassland in the summer. It can look really attractive.”
In 2021, Oki's team at UC Davis identified Lomandra confertifolia ssp. pallida "Pom Pom" Shorty and Rosa "Sprogreatpink" Brick House® Pink as two of the best low-water plants in the trial.
“The useful tip or information that is shared at the end of each trial is the selection and designation of plants as Blue Ribbon winners. These are the plants that looked good with an overall rating of 4 or higher throughout and were on the low (20%) water treatment,” said Natalie Levy, associate specialist for water resources, who manages the project at the UC ANR South Coast Research and Extension Center.
How plants earn a blue ribbon
Each trial year, the selection of new plants is based on research recommendations and donated submissions from the nursery industry. The landscape plants are trialed in full sun or 50% shade cover.
Irrigation treatments are based on the rate of evaporation and plant transpiration (evapotranspiration) measured through a local California Irrigation Management Information System (CIMIS) weather station that provides a reference evapotranspiration (ETo) rate.
Three levels of irrigation are provided to the plants equal to 20%, 50%, and 80% of ETo. The volume of water applied is the same at each irrigation based on soil characteristics, but the interval between applications varies with weather and the treatment. Using this method, irrigations for the 20% treatment are less frequent than the 80% treatment.
“The 20% treatment during the 2022 trial was irrigated an average of once per month while the 80% treatment was irrigated weekly,” explained Levy.
During the deficit irrigation trial, monthly height and width measurements are taken to determine the plant growth index. Monthly qualitative aesthetic ratings on a scale of 1 to 5 are determined for foliage appearance, flowering abundance, pest tolerance, disease resistance, vigor and overall appearance.
A second round of flowering abundance and overall appearance measurements are also taken to capture more of the blooming period. For example, UCLPIT identified in the 2020 trial at South Coast REC that the "Apricot Drift" rose had a mean overall appearance score of 3.5 out of 5, deeming it “acceptable to very nice” and a low water use plant within the Water Use Classification of Landscape Species or WUCOLS guide.
Project expands options for landscape planting
“(WUCOLS) only has 3,500 plants in it. There are guesses that there are close to 10,000 cultivars in urban landscapes in California, if not more,” said Oki. “WUCOLS also didn't have numerical ratings. Instead, you'll see verbal ratings like ‘low water use' or ‘high water use.'”
The UCLPIT project has not only developed numerical recommendations for irrigation, but it has also added new landscape plants that are compliant with California's Model Water Efficient Landscape Ordinance. In fact, UCLPIT's data is one of the few sources that can be used to supplement WUCOLS.
Geographic diversity of trial sites adds to knowledge base
In addition to UC Davis and South Coast REC in Irvine, the trials have expanded beyond California as the Climate-Ready Landscape Plants project and is in progress at Oregon State University, University of Washington, University of Arizona and Utah State University thanks to a USDA/CDFA grant awarded in 2020.
Lloyd Nackley, associate professor of nursery production and greenhouse management at Oregon State University, is the principal investigator of the trial in the Portland metro area, which is entering its third year.
“People know that there are drought tolerant plants, but there are many. We're trying to highlight lesser known or newer varieties. And even though the trial is three years, most gardeners would hope that their garden lasts longer than that,” said Nackley.
One of the observations that Nackley recalls is of the Hibiscus Purple Pillar plant. Unlike the trial at South Coast, the Purple Pillar did not perform well in Oregon in the spring.
“It wasn't until August that we saw the plant bloom and begin to look like what we saw from South Coast in April,” Nackley said.
Ursula Schuch, horticulture professor and principal investigator of the trial taking place at the University of Arizona, was also surprised at the range of performance among different plant types and the effects of irrigation, heat and temperature.
“This research will reassure green industry professionals that they can stretch their water budget to successfully cultivate more plants, watering them according to their needs instead of irrigating every plant according to the highest water-using plants,” said Schuch.
Although research is only conducted in the West, the hope is that there will be trials in other regions of U.S.
Doing so would yield comprehensive information about the plants and their performance in different climates. As extreme weather events persist in the U.S., disease pressure and risks do too. Trials throughout the country would provide location-specific data regarding disease susceptibility.

Neas named 4-H advisor for San Mateo, San Francisco counties
Sally Neas began working as the 4-H youth development program advisor for UC Cooperative Extension in San Mateo and San Francisco counties on Aug. 1.
In her role, Neas incorporates environmental education into youth programs at Elkus Ranch and 4-H community clubs. She is also responsible for conducting research and developing new programs.
Neas has worked in youth development and environmental education for several years. When she first moved to California 12 years ago, she worked for Veggielution Community Farm in San Jose and helped launch their first youth development program.
Since then, she has worked in after-school programming focused on gardening and nutrition in Santa Cruz and has dedicated her time and energy to engaging youth in conversations about climate change.
“I'm interested in building conversations around climate change that focus on culturally relevant and personally meaningful approaches. Not a deficit approach that asks what we're going to give up, but what can we do as a collective,” said Neas.
Neas earned a doctorate in environmental education at UC Davis and a bachelor's in environmental studies from the University of the South in Tennessee.
Neas centered her dissertation on how young people understand and define climate change. Her research relied on oral histories collected from “youth that, historically, are not represented in the climate change space” such as youth of color and queer youth. To capture their stories, Neas initiated a digital storytelling project, drawing on the collaboration between art and science.
“I really felt bothered by not hearing educators adequately address climate change. It felt like a looming elephant in the room, where we either didn't talk about it at all or what we were saying wasn't helpful,” she said.
According to Neas, youth have a moral compass that, unlike in adults, has not been so degraded. Their creativity, compassion and drive inspire Neas to preserve these parts of herself. Moving forward, she is eager to create programs that are inclusive and representative of all youth that she serves.
Neas is based in Half Moon Bay and can be reached at seneas@ucanr.edu.
Norville named fire advisor in Sonoma, Napa and Marin counties
Tori Norville started on Aug. 1 as the new UC Cooperative Extension fire advisor for Sonoma, Napa and Marin counties.
In this capacity, Norville will work with residents and organizations within the wildland-urban interface to encourage and cultivate fire-adapted communities. She aims to provide education and outreach on home hardening, defensible space and the importance of forest and fuel management on the landscape.
While pursuing her bachelor's degree in forestry and natural resources at Cal Poly San Luis Obispo, Norville became interested in “disturbance ecology” – how factors such as disease, insects and fire affect landscapes and environments.
“Many of the forest health problems we are seeing are stemming from a lack of disturbance, which traditionally was fire,” Norville said.
Her understanding of fire and its effects deepened during her master's degree studies in forestry science (also at Cal Poly SLO), as well as through her seven years with CAL FIRE at the Jackson Demonstration State Forest in Mendocino County. She worked as the Registered Professional Forester for its Timber Sales Program, and then the Research and Demonstration Program.
Norville's firsthand experiences from the past few fire seasons have helped shape her goals and approach. She hopes to “work holistically with disturbances” – specifically fire – on the landscape to foster healthy forests and ecosystems that are adaptable and resilient, while also researching the environmental and social aspects of fuel-reduction projects and prescribed fire.
“Hopefully, I can begin to change the perception of fire from something we need to fear, to something we respect,” she said.
Norville, based at the UCCE office in Santa Rosa in Sonoma County, can be reached at trnorville@ucanr.edu.
Atim named UCCE specialist studying crop drought resilience
Jackie Atim began working as a UC Cooperative Extension specialist affiliated with UC Merced on July 11, based at Kearney Agricultural Research and Extension Center in Parlier.
Atim's work will include applied research focused on abiotic stress, which includes plant stress caused by extreme temperatures, high salinity, floods, drought or nutrient deficiency. In particular, she will be studying the genetic makeup of sorghum, its resistance to drought and the value it contributes to byproducts such as bioenergy.
California, as Atim explained, is an ideal place to study drought resilience given its semi-arid climate and water challenges. She is hopeful that California will establish sorghum as a climate-smart crop for forage and grain to address the challenges facing water-stressed production systems.
Furthermore, Atim will focus on “transforming science that can be consumed by ordinary farmers and growers alike.”
While Atim understands the importance of research-based decision-making, she also recognizes the challenges that non-academic audiences experience when applying such information. As a start, Atim anticipates collaborating with communications experts to simplify research findings and create visually appealing resources.
Before joining UC ANR, Atim worked as a plant pathologist for the National Agricultural Research Organization based at Mukono Zonal Agricultural Research and Development Institute in Uganda. In addition to pathology, Atim has expertise in plant breeding and entomology.
Atim earned a bachelor's degree in agriculture and education from Kyambogo University in Uganda. She has a master's degree in plant biotechnology from Wageningen University in the Netherlands, and a doctorate in agriculture, plant breeding and entomology from the University of Greenwich in the United Kingdom.
Atim can be reached at jatim@ucanr.edu. Follow her on Twitter @JackieAtim2.

Mukherjee named urban and small farms advisor
Amrita Mukherjee joined UC ANR on April 1 as an urban agriculture and small farms advisor serving Los Angeles, San Bernardino, Riverside and Orange counties.
Mukherjee's priority is to understand small farms' practices and needs, and to identify opportunities for improvement and/or collaboration. One challenge that Mukherjee is eager to overcome is getting information to farmers in a timely and organized manner.
“There's so much information out there and it's hard to know who is doing what,” she said. By implementing a communication system, Mukherjee believes that supporting small farms will become more efficient.
Originally from Bangladesh, Mukherjee grew up in a family of farmers and understands the struggles farmers encounter as laborers and as a business. Her upbringing inspired her to not only pursue a career in agriculture, but to alleviate the hardships that often burden farmers.
Previously, Mukherjee worked for the International Rice Research Institute where she examined flash flood risk-management in her homeland. She also worked for the Horticulture Innovation Lab management team at UC Davis as an assistant specialist in Bangladesh, focused on nutrition impacts of horticultural innovations.
Mukherjee earned a bachelor's degree in agriculture from Khulna University, a master's degree in biotechnology from Bangladesh Agricultural University, and a master's degree in horticulture, plant biology and post-harvest physiology from Kansas State University.
While she has dedicated the first few months of her role to networking, Mukherjee feels that building rapport with small-scale farmers is an ongoing process that is crucial to her role as an advisor.
When asked what she is most excited about, Mukherjee said that she wants to help farmers grow – not just their crops, but their business strategy and network. “I don't want to be a supervisor, I want to be a connector,” explained Mukherjee.
Mukherjee is based at the UC Cooperative Extension office in Highland in San Bernardino County and can be reached at amukherjee@ucanr.edu.

New research fills gap on best practices for California carrot production
One doesn't need to be a seasoned farmer to know that growing conditions in Canada are completely different than those found in the low desert of California.
And yet, for many years, studies conducted in Canada were used to generate nitrogen uptake data for the California carrot production system, so growers managed their fields based on their own experiences – and that research conducted thousands of miles to the north.
Carrots had been among the crops grown in California that did not have site-specific data to suggest the best source, rate, timing and placement of nitrogen, in the highly variable cropping seasons and locations throughout the state. That's why new information – based on local research and published in August – is invaluable to farmers in Imperial and Kern counties, where the majority of the carrots in California are grown.
Two years of data from two experimental trials at UC Agriculture and Natural Resource's Desert Research and Extension Center – as well as from 10 commercial fields – produced key recommendations for farmers to make the most of their irrigation and nitrogen applications.
“The point is we developed information in your field, based on your practices, your climate, your production system – and this is what is really happening,” said Ali Montazar, UC Cooperative Extension irrigation and water management advisor for Imperial County. Montazar conducted the study alongside Daniel Geisseler, UCCE nutrient management specialist at UC Davis, and Michael Cahn, UCCE irrigation and water resources advisor for Monterey County.
With reliable data gathered under real-world conditions, Montazar said growers now have solid reference points for when – and at what rate – to irrigate and apply fertilizers in the low desert environment. One of the key findings, for example, was that the carrots' nitrogen uptake is generally low in the first 40 to 50 days, so growers are advised to limit their fertilizer application during that period.
Then, by tailoring those basic guidelines to their own site-specific situation and optimizing their practices, growers can maximize the amount of nitrogen taken up by the carrots – and minimize the amount that is leached out.
“Improving irrigation and nutrient management in the desert production system is what local growers are themselves trying to achieve. With improving efficiency and reducing nutrient leaching, we can improve the quality of water in the Salton Sea,” said Montazar, noting the longstanding challenges of reducing contaminants from irrigated lands to protect its unique ecosystem and wildlife.
While contamination of groundwater is not a critical issue in the desert, the best practices in this study can also help carrot growers in parts of California where nitrogen leaching into groundwater and drinking water supplies is a greater concern.
Montazar is currently leading a team in studying carrot-growing management practices under slightly different conditions in Kern County, with the hopes of publishing findings in late summer 2022.
The Imperial County study, “Spatial Variability of Nitrogen Uptake and Net Removal and Actual Evapotranspiration in the California Desert Carrot Production System,” is published in the journal Agriculture, and can be found at https://doi.org/10.3390/agriculture11080752. Findings and recommendations also appear in Progressive Crop Consultant: https://progressivecrop.com/2021/09/new-knowledge-based-information-developed-to-enhance-water-and-nitrogen-use-efficiency-in-desert-fresh-market-carrots/.
Funding for this study was provided by the California Department of Food and Agriculture's Fertilizer Research and Education Program, as well as the California Fresh Carrots Advisory Board.
World Food Center at UC Davis will tackle global issues
The new World Food Center at UC Davis will take on a broad purview related to food, including sustainable agricultural and environmental practices, food security and safety, hunger, poverty reduction through improved incomes, health and nutrition, population growth, new foods, genomics, food distribution systems, food waste, intellectual property distribution related to food, economic development and new technologies and policies.
With rapid global population growth occurring on smaller amounts of arable land, coupled with the expected impacts of climate change on food production, understanding the sustainability of food into the future is critical.
The new center’s website notes, “The World Food Center at UC Davis takes a ‘big picture’ approach to sustainably solving humanity’s most pressing problems in food and health. By bringing together world-class scientists with innovators, philanthropists and industry and public leaders, the center will generate the kind of visionary knowledge and practical policy solutions that will feed and nurture people for decades to come.”
In establishing the World Food Center, UC Davis Chancellor Linda Katehi said, “We did this to fully capitalize on our depth and expertise as the world’s leading university for education, research and scholarship on all aspects of food, but especially the nexus between food and health.”
UC Davis is the top-ranked agricultural university in the world, and California is the major producer of vegetables and fruit in the nation. Tom Tomich, director of the Agricultural Sustainability Institute and professor in the Department of Environmental Science and Policy at UC Davis, says of the World Food Center’s location at UC Davis, “There’s no place else that has the right mix of educational programs, research facilities, and the engagement with the state.”
The major academic disciplines surrounding food are found at UC Davis — agriculture, the environment, medicine, veterinary medicine, engineering, social and cultural sciences, and management. More than 30 centers and institutes at UC Davis will be pulled together through the World Food Center. The combination of scholarship, leadership, and partnerships at UC Davis has already established the campus as a center for food-related science and outreach. This new center will reinforce that strength and broaden the university’s ability to tackle tough global issues related to food.
Although the founding director of the center has yet to be named, Josette Lewis, Ph.D., was recently appointed as the associate director of the World Food Center. Her background on international research and development for the U.S. Agency for International Development, and director of its Office of Agriculture, honed her skills to take on the World Food Center. It was at US AID that she worked on a major global hunger and food security initiative, establishing her expertise on issues related to global agricultural development and food security.
As the new World Food Center becomes fully developed, it will be well-positioned on campus to continue to solve the major global issues related to food that are a hallmark of UC Davis.

Some hae meat, and canna eat . . .
"Some hae meat, and canna eat,
And some wad eat that want it . . ."
The words are old and a little hard to understand, but they tell a story that's as true today as when the poet Robert Burns spoke them back in the 1790s. They were old words even then. Always, it seems, there are those of us who are fortunate enough to eat well and those of us who go hungry, even in a country as rich as ours.
One morning last May, I got to meet some folks who help ease that hunger in the community where I live. That morning I drove with my wife to an industrial area on the northeast side of Woodland, California, where the Food Bank of Yolo County does its business. Outside the warehouse door delivery trucks from local markets, chain stores, farms, and other food sources came and went, mingling with buyers' pickups and trailers from churches and other charitable groups.
The big trucks were there to deliver what many retailers would consider marginal goods: bread, dairy products, meats, and canned and dry goods that were moving too slowly off the shelves or getting too close to their sell-by dates; a cardboard harvest bin of loose carrots in the walk-in, donated by a grower who was getting ready to put in a new crop; 50-pound sacks of potatoes or onions that were either too much for the food service market or were set aside by generous handlers or a government agency for exactly the purpose they were about to serve: to feed the hungry.
These days about 35 percent of the stock you can see in this Food Bank warehouse has been donated outright. The rest comes from government agencies or direct purchases from the California Association of Food Banks. A few years ago the directors of the Food Bank of Yolo County shifted their focus toward providing clients with fresher, more nutritious food, and since then they have brought their fresh produce sales from about 50,000 pounds a year up to a high of 1 million pounds in 2010.
That morning in May my wife and I joined other groups of buyers inside the warehouse, each of us picking through the low-priced goods for just the right mix of products to refill the shelves of a soup kitchen or—as in our case—a local food closet. Loaves of bread, a case of canned tomatoes, a box of apples, macaroni and cheese mix, a shrink-wrapped bundle of bags of flour. We loaded our wheeled dolly three times: first came the bread, which a food bank volunteer weighed before we loaded it into the truck; then the produce, likewise weighed on the dolly and loaded; and finally the canned and dry goods, which are priced by the case. Five flats of eggs we put in the pickup's back seat for a smooth ride. For a little less than $100 we got enough food to fill the truck.
A short trip then took us back to the food closet at our church, where 8 or 10 women and men, most of them well into their retirement years, bustled around the edges of the sorting table that filled the middle of the small room, stacking cans on shelves, putting bread, tortillas, and eggs into the refrigerators, doling potatoes, onions, rice, and beans from 50-pound sacks into smaller, consumer-sized bags, and pointing out to me firmly and kindly each time I put a box or bag down in the wrong place. Which was pretty often. Before an hour was up, the closet was stocked and locked up and ready for food distribution the next day. Two distributions a week from our closet alone can serve up to 50 families in need.
There's plenty that you can do, too, to help relieve hunger in your own community. Find your nearest food bank on the California Association of Food Banks website, or ask around to find out about local food closets or soup kitchens.
Then all you need to do is pitch in. If you've got the time, they've got the need.
