2017 by the numbers:
- 172 volunteers
- 332 garden centers
- 45 counties
According to PlantRight's Spring Nursery Survey Fact Sheet, the rate of nurseries selling invasive plants continues to decline. In 2014, 44% of nurseries surveyed were selling locally invasive plants; this rate dropped to 35% in 2015, to 31% in 2016, and 29% in 2017.
Of the nurseries that were selling any invasive plants in 2017, only 8% had more than one species of invasive plant for sale. This is down from 2016, when 10% of stores (that sold any invasive plants) had more than one invasive plant for sale.
No Spring Nursery Survey in 2018
PlantRight will not be conducting the Spring Nursery Survey in 2018. This one year break from the survey allows PlantRight to make a more concerted statewide outreach effort to landscape professionals (e.g. architects, designers and contractors), and the most influential water districts promoting sustainable landscaping.
Successfully engaging these professionals and districts will accelerate PlantRight's work to keep invasive plants off California wildlands and promote climate appropriate alternatives. That's because these groups have significant influence on the nursery supply chain -- what horticultural growers grow, what plants get specified in landscape design, and the plant material that contractors source. Engaging water districts is a cost effective way to educate members of the gardening public, especially those interested in replacing thirsty lawns with lovely looking, climate appropriate landscape plants.
Survey Pause is No Pause in Planting Right
This pause in surveying is in no way a pause in planting right. PlantRight.org remains a trusted resource for UC Master Gardener volunteers. Engage with PlantRight on social media, including: Facebook, Twitter, YouTube, and Instagram. Let PlantRight know about any good works or upcoming events so that it can share your news and announcements on social media or in its email newsletter. You can support PlantRight's Retail Nursery Partners by shopping at their stores.
Volunteers interested in learning more about invasive ornamental plants in California can still earn continuing education hours by completing PlantRight's Continuing Education Program. The online format makes it easy for anyone with an account to participate. After completing the curriculum, participants can pass a 12-question quiz and earn a certificate of achievement.
PlantRight is committed to being UC Master Gardener volunteer's go-to resource for science-based information about horticultural invasive plants. UC Master Gardener volunteers and coordinators can contact PlantRight anytime with questions, PlantRight@suscon.org.

It's that time of year again. Soon, over 150 UC Master Gardener volunteers will head to plant nurseries throughout the state with clipboards, cameras, and data sheets in hand. In this 8th year of the survey, they will be searching for invasive ornamental plants. But why?
The nursery survey is how PlantRight measures what is happening in California's retail nursery industry, and none of it would happen without the survey volunteers. In 2016, 175 volunteers (many of them UC Master Gardener volunteers) were trained by PlantRight to survey for invasive plants at retail locations throughout the state. If approved by your county, hours spent participating in the survey can count towards certification volunteer hour requirements. Check with your local county program coordinator.

Why is the survey important?
The information volunteers gather is vital to PlantRight for three main purposes:
1. Tracking the sale of invasive plants currently on the plant list, and retiring those that have been largely phased out of retail.
To keep the list relevant, as plants from the original list are no longer sold, they are “retired.” To retire a plant, it must be found at less than 1% of nurseries surveyed for 3 years in a row. This doesn't mean that they are gone from our landscapes. Plants like Scotch broom (Cystisus scoparius) and arundo (Arundo donax) have already invaded wildlands in California, and there's still much work to be done to control their spread. Since the invasive plant list was first published in 2006, 15 plants have been retired, which is excellent progress. You can help with these retired plants by removing them if they are on your property or volunteering with groups that remove invasive plants.
2. Helping PlantRight determine whether or not to add candidate plants to the plant list.
In late 2012, PlantRight recruited several horticultural experts (all volunteers, from diverse sectors of industry, academia and conservation) to establish their Plant List Committee. These individuals engage in the complex, involved, and time-intensive process of working with PlantRight to decide which surveyed plants to add to the invasive plant list and which non-invasive alternatives to suggest. Each fall, PlantRight solicits input from the Plant List Committee and an extended network of experts to see what plants might be hopping the garden fence and escaping into wildlands.
To appear on PlantRight's invasive list, a plant must meet the following criteria:
- When evaluated by PlantRight's Plant Risk Evaluator (PRE), it rates as being “high risk” or is on the Cal-IPC Inventory
- It is found in 3% or more retailers surveyed in the annual Spring Nursery Survey
- Its invasive range is large enough to warrant action, and its inclusion is supported by both the Plant List Committee and Steering Committee
There's one more way PlantRight uses the survey information – helping use their energy and time strategically.
3. Informing industry outreach strategy with information about sales in different regions and store types.
Get an exclusive look at the results of this year's survey (before they go online) by attending the 2017 UC Master Gardener Conference in Long Beach on August 22-25, where PlantRight will be giving a presentation and celebrating the participation of UC Master Gardener volunteers in this effort.
Can't participate in the survey?
You can still help by sharing what you've just read, sharing the Plant List or Mexican feathergrass species spotlight, shopping at PlantRight retail partner locations, and educating your friends and neighbors. You can also participate in their Continuing Education program if you would like to expand your knowledge about invasive garden plants in California. You are welcome to still watch the webinar if you can't participate in the survey. A recording of each webinar will be shared on the PlantRight YouTube channel immediately after it concludes.

PlantRight defines “actionable awareness” as what happens when individuals and businesses are made aware of an opportunity to be part of the solution to California's costly (economically and environmentally) invasive garden plant problem, and make a conscious decision to act. Invasive plants (despite the fact that many are deceptively beautiful and drought resistant) outcompete native plants, alter soil chemistry, increase wildfire risk, clog our waterways and can severely compromise agricultural yields and real estate value. If that weren't enough, invasive species are the second greatest threat to biodiversity after human development.
Awareness of these facts alone will not fix any of these issues; however, add action to the mix and you have a proven formula for problem solving. PlantRight's idea of problem solving is collaborating with the industry to voluntarily phase invasive plants out of the supply chain and replace them with high-quality (i.e. non-invasive) plants. Voila! Together we prevent new invasive garden plants from wreaking havoc on our wild lands and taxpayer wallets.
The fact that 50% of California's invasive plants are of horticultural origin (Bell et al. 2007) is a source of both conversation and dismay. Yet from PlantRight's perspective this 50% is a great source of optimism because it's proof of a huge opportunity the nursery industry can play in preventing future invasive plant introductions. In past decades ornamental plant breeders and growers had little or no ability to predict a plant's invasive risk in a given region, and most invasions were well-intentioned accidents. Lucky for us we finally have science-based plant risk evaluation tools to prevent new invasive plant introductions. Not so lucky for us is that popular plants travel, and a delightful Dr. Jekyll plant in one region, may become a hideous Mr. Hyde plant and landscape transformer in a different region. It's about the right plant in the right place, but just where to begin, if we're to turn this talk into actionable awareness?
In the beginning there was lots of conversation and lots of listening sessions that Sustainable Conservation conducted with a diverse group of nursery industry stakeholders, from large ornamental growers, retail nurseries, plant scientists, trade associations and government agencies. University of California Agriculture and Natural Resources (UC ANR) has been part of this group from the start, providing academic expertise on weeds and calculating their risk. This group's official moniker is “California Horticultural Invasive Prevention,” but we prefer Cal-HIP.
With a couple years of listening and learning under our belts, and funding from Sustainable Conservation, the PlantRight program was ready for action: action engaging the nursery industry in voluntarily phasing our invasive ornamental plants and promoting, in their place, non-invasive alternatives.
Our first order of business was to measure the scope of the problem and establish a baseline. Working closely with plant science experts to identify the most problematic invasive ornamental plants, and industry experts to identify non-invasive alternatives, we created our first PlantRight plant list. If you can measure it you can manage it, we like to say - to do this, we rely on an annual Spring Nursery Survey. Each spring, partner with UC Master Gardener volunteers to survey more than 200 nurseries and garden centers around the state, and in the process track the retail market for invasive garden plants in California.
Along with informing PlantRight's program strategy, the annual survey allows us to keep PlantRight's plant list manageable and up to date – we add new invaders and retire those that are largely phased out of the trade. It is our program's calling card, and the starting point for conversations with prospective partners and skeptics, alike. It has earned the enthusiastic support of California Certified Nursery Professionals (CCNPro), SaveOurWater, and more.
A Little Less Fight, a Little More Spark
Buying non-invasive means many things, including protecting native species, being good stewards of our beautiful open spaces and waterways, being fiscally responsible and preventing additional taxpayer dollars going to avoidable invasive plant eradication efforts. Buying non-invasive plants is casting a vote for the kind of world you want to live in.
So, why on earth do people buy invasive plants in the first place? (Hint: One big reason has to do with what happens when you turn off the lights). Yep, people who purchased invasive plants were in the dark – they did not know.
In 2013, we learned that the primary drivers behind consumer purchases of invasive plants are: 1) aesthetics – it looks good; and, 2) there was no information on the plant indicating “invasive.” In other words the majority of invasive plant purchases (by consumers) are impulse purchases and would not have occurred had the plant been properly identified as “invasive.”

“2014 saw many common invasive plants decline in availability, yet some are more popular than ever. Help us prevent the next big invasive by making the 2015 survey our most successful yet!” –Chris Crawford, PlantRight Survey Manager
2014 Survey Highlights
Driving this positive change was a large decrease in periwinkle (Vinca major), dropping from 17% in past years to 9% of surveyed stores. However, the number of stores selling the most recently added invasive plants on PlantRight's list (updated in early 2014) increased. Notably, the drought-tolerant emerging invasive Mexican feathergrass (Nassella tenuissima) increased in prevalence from 27% in 2013 to 38% in 2014.
A comprehensive report and simplified fact sheet detailing the results can be found on the Spring Retail Nursery Survey – 2014 Fact Sheet. These results act as PlantRight's guiding light, shaping its strategy and helping it move forward collaboratively with the nursery industry.
2015 New Plant List
After a year-long review, PlantRight is very excited to share its brand new 2015 list of Suggested Alternatives for Invasive Garden Plants. This list identifies the top ten priority invasive plants for sale in California and provides recommendations on beautiful alternatives. Without the help of the UC Master Gardeners and the data collected from the annual spring survey, the new and improved list would not have been possible.
-- For questions, contact Chris Crawford, PlantRight Survey Manager, at email@example.com or (415) 977-0380, ext. 331.
Mexican Feather Grass (Nassella or Stipa tenuissima) is a wildly popular ornamental grass used by home gardeners and landscape design professionals. Mexican Feather Grass is loved for its graceful, delicate and fine texture – it grows out in a cascade like a beautiful fountain. Plus it is extremely drought tolerant adding to its allure. It's no wonder this ornamental grass has been enthusiastically used in home landscapes. But - don't be fooled by this invasive beauty!
Mexican Feather Grass was recently added to PlantRight's list of invasive plants in California. It produces tens of thousands of seeds, which are dispersed by wind, water or contaminated soil – as well as via automobiles and animal droppings. The seed-bank can persist for more than four years and the plant commonly self-sows in California. Mexican feather grass is capable of overcoming native plants and animal species once it becomes established.
It crowds out pasture grass species as well as native grasses in coastal areas and is found in all landscapes, including: urban spaces, agricultural areas, forests, open grasslands, riparian zones, disturbed land, and shrublands.
Working to Stop Distribution
PlantRight works with leaders in the nursery industry, conservation groups, plant scientists and professional landscapers to find cost-effective ways to stop the sale of invasive plants and Mexican feather grass is at the top of their list. PlantRight is currently working with one of the top growers of Mexican feather grass to stop the sale of 14,000 plants that are ready to ship to retailers. These 14,000 plants are capable of producing more than 980 million seeds each year.
PlantRight Recommended Alternatives:
- Blue grama grass (Bouteloua gracilis 'Blonde Ambition')
- Priarie dropseed (Sporobolus airoides)
- Mexican deer grass (Muhlenbergia dubia)
- Pink Muhly (Muhlenbergia capillaris, esp. 'White Cloud')
- Autumn moor grass (Sesleria autumnalis)
