Planting Right with PlantRight

UC Master Gardener Program partner PlantRight had a information packed LIVE talk about their efforts to phase out invasive plants in California.  Alex Stubblefield, PlantRight project manager led the LIVE talk featuring their mission, partners, work and what we can do to help stop invasive plants. If you didn't get to join us LIVE you can watch the video below.



Here is a quick written recap of the LIVE talk:  

What is an invasive plant?

An invasive plant is a plant that is non-native to the ecosystem under consideration, and whose introduction is likely to cause economic or environmental harm, or harm to human health. Visit PlantRight's website for more detail.  

What's the problem?

Invasive plants harm California's environment and economy in many ways. They can overtake crops or rangeland; harm wildlife by eliminating plants they need for food and shelter; clog waterways used for commerce or recreation; and increase fire hazards and flood risk.

What's the alternative?

There is no shortage of superior alternatives. The vast majority of garden plants are well behaved and will never become an invasive problem. Our plant list includes several suggested alternatives for each invasive plant

How can I help?

Be a part of the solution by planting right. Whether you are a retail nursery, grower, landscape professional, or home gardener — everyone can play a critical role in preventing the spread of invasive plants. PlantRight has many educational resources and materials available online to read and share. 

Plants to watch!

Although the list of plants PlantRight is currently working with is not all-inclusive there is a list of plants to watch.  Find the current list of plants to watch on their website

LIVE: Planting Right with Plant Right Talk

UC Master Gardener Program and PlantRight have partnered for a LIVE Facebook and YouTube talk about invasive plants on Jan. 19at noon. Invasive plants harm the environment and cost California millions of dollars to monitor and manage each year. Almost half of invasive plants in the state get their start through the nursery trade, and many invasive plants are still legal to sell today. Educating people on the impact of invasive plants is just a small piece of removing them from the environment.

What is PlantRight?

PlantRight is a program that works together with the nursery industry, conservation, science, and government agencies to identify and help nurseries voluntarily phase out invasive plants. For each invasive on the list, PlantRight suggests safer, regionally appropriate alternative plants. PlantRight's goal is to teach everyone from landscapers to home gardeners how toplant “right”.

UC Master Gardener Partnership

The partnership between the UC Master Gardener Program and PlantRight supports planting the right plant in the right place. The right plant in the right place leads to a healthier environment and healthier plants. Because of UC Master Gardener volunteer efforts, PlantRight can survey plant nurseries all over California.  Armed with clipboards, cameras, and data sheets, specially trained volunteers collect and report to PlantRight. 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 mostly phased out of retail.
  2. Helping PlantRight determine whether or not to add candidate plants to the plant list.
  3. Informing industry outreach strategy with information about sales in different regions and store types.

UC Master Gardener volunteers play a vital role in educating the public on right plant, right place, and helping PlantRight survey California's plant nurseries.

Planting Right with PlantRight, LIVE on Jan. 19

The UC Master Gardener Program is celebrating this great partnership by hosting a free LIVE talk titled Planting Right with PlanRight. No registration is required. The discussion will be live-streamed to Facebook and YouTube on Tuesday, Jan. 19 at noon. Guest speaker, Alex Stubblefield, PlantRight Project manager, will be educating us on invasive plants in California and offering plant alternatives as well as the importance of the annual plant survey.

LIVE talks are an authentic and interactive way to interact with our audience in real-time. Share the Facebook and YouTube Live opportunity with your friends on social media and tune in to the UC Master Gardener Program LIVE broadcast! In the comments section below, let us know what topics or questions you would like answered on Tuesday, Jan. 19, or ideas for future LIVE topics.

PlantRight’s Spring Retail Nursery Survey Re-launches in 2020

What's in store this spring? That is exactly the question on PlantRight's mind as the program launches its 9th Annual Spring Retail Nursery Survey. PlantRight's spring survey helps keep a pulse on the sale of invasive plants in California. 

The Spring Retail Nursery Survey began in 2009 under the management of the 501(c)3 non-profit Sustainable Conservation. After development of a comprehensive program and eight successful surveys, Sustainable Conservation transferred the management of the PlantRight program to Plant California Alliance in 2019. Plant California Alliance, an association of horticultural industry professionals, is a great fit to host the PlantRight program. Now, under the new leadership, PlantRight is excited to announce that they are re-launching the survey.

The nursery survey has come a long way from its debut year in 2009 when it included 75 stores in 27 counties to its most recent survey in 2017 which included 332 stores in 45 counties. With almost half of all invasive plants in the state being introduced through the horticultural industry, the nursery survey is an important source of information on the prevalence of invasive plants in California's gardens and landscapes. PlantRight looks forward to continuing the legacy of successful data collection.

The survey would not have had the success it has had so far without the hard work of UC Master Gardener volunteers. Each spring, the nursery survey is conducted throughout California through the participation of volunteers from the UC Master Gardener program and a few other conservation groups.

How PlantRight Uses the Data

The information gathered during the survey allow PlantRight to:

  1. Collaborate effectively with thousands of plant retailers, wholesalers and growers;
  2. Provide gardeners with information about invasive plants and choosing beautiful non-invasive alternatives for their gardens;
  3. Inform our strategy, measure our progress, and keep our plant list relevant.

PlantRight works in partnership with the nursery industry and only releases aggregated data that protects the identity of, and data from, the stores that are surveyed.

PlantRight Takes Time Out on Survey in 2018

The UC Master Gardener Program and its volunteers have been a key partner in PlantRight's annual Spring Nursery Survey  since its inception in 2010. Last year marked the 8th year of the Survey, and thanks to UC Master Gardener volunteers, it was a huge success!

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. 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,

With PlantRight, You Too Can Prevent the Sale of Invasive Plants

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.

  • Take a short quiz to demonstrate your newfound knowledge. 
  • Access to survey materials and claim your survey store (or multiple stores. 
  • Visit the store/s and record information about any invasive plants or candidate plants being sold. 
  • Submit information to PlantRight

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.

Scotch broom (Cystisus scoparius), a familiar sight in California wildlands. It has invaded at least 23 counties in California and can produce up to 12,000 seeds per plant, making it difficult to control once established. Photo by Joe DiTomaso.
The first PlantRight invasive plant list was developed using the California Invasive Plant Council (Cal-IPC) Inventory as a starting point and included 19 plants, focusing on the highest priority invasive plants still sold in garden centers.

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.

There are 7 plants currently on PlantRight's list of invasive plantsThe 2016 survey results for these 7 plants can be found in the Fact Sheet and Full ReportFour of these plants were part of the original list of 19: green fountain grass (Pennisetum setaceum),pampas grass (Cortaderia selloana)highway iceplant (Carpobrotus edulis), and big-leaf periwinkle (Vinca major)

Three plants were added in 2014Mexican feathergrass (Stipa/Nassella tenuissima)yellow flag iris (Iris pseudacorus), and water hyacinth (Eichhornia crassipes).  

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.

While green during the wetter part of the year, this grass will turn golden brown at the top as its seeds ripen — its many, many seeds. Each plant can produce thousands of seeds, which are dispersed by wind, water, contaminated soil, automobiles, and animals. Photo by Jan Tilford.

To appear on PlantRight's invasive list, a plant must meet the following criteria:

  1. When evaluated by PlantRight's Plant Risk Evaluator (PRE), it rates as being “high risk” or is on the Cal-IPC Inventory
  2. It is found in 3% or more retailers surveyed in the annual Spring Nursery Survey
  3. 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.

PlantRight has worked across the nursery supply chain to raise awareness about invasive plant issues and benefits of planting right. In recent years they been recruiting retail nursery partners. These partners commit to sell exclusively non-invasive plants?—?you won't find any plants on our plant list at a retail nursery partner's store. Knowing who is selling invasive plants and in what regions of the state helps focus their efforts where they will have the greatest impact.

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.
