I saw Elvis today. Really! He’s quite the regular at Sustainable Conservation’s San Francisco headquarters these days. More than a titan among musical icons “The King” has become a muse to the PlantRight team, especially this National Invasive Species Awareness Week. We love Elvis’ A Little Less Conversation because it might as well be our theme song for actionable awareness. We can’t guarantee you’ll be dancing along by the end of this article, but we do guarantee providing you with a few awareness-raising resources, a deeper understanding of what’s holding back the hold-outs from taking positive action, and most importantly what we can do about it.

Many Californians appear to be taking up Gov. Jerry Brown's call for the removal of 50 million square feet of lawn energetically and enthusiastically. But all that energy may be misplaced: As homeowners and businesses seek out drought-tolerant, low-water plants at local nurseries and big-box garden departments, they may unwittingly be picking up invasive plants that wreak havoc on the state's ecology.

They’re usually gorgeous; that’s the start of the problem. They grow easily and often freely, propagating offspring effortlessly. With a little water and time, they really do take over.

And that’s when a beautiful ornamental plant becomes an invasive thug...

California’s drought crisis is driving low-water landscaping: lawns are coming out, xeriscaping is going in. Fortunately, water agencies, nurseries, garden media and our friends at Save Our Water are all promoting drought-tolerant plant lists to guide purchasing decisions and reduce water usage.

Unfortunately, in this rush for water conservation, invasive plants are creeping onto some of these lists! Maybe you’ve already noticed…

Choosing the right plant for the right place is a key element in protecting California’s rich natural ecosystems. When used appropriately, plants offer us nourishment, beauty, sanctuary, and habitat; but some plants may have adverse environmental consequences.

Weed Risk Assessment (WRA) methods for evaluating invasiveness in plants have evolved rapidly in the last two decades. Many WRA tools exist, but none were specifically designed to screen ornamental plants prior to being released into the environment. To be accepted as a tool to evaluate ornamental plants for the nursery industry, it is critical that a WRA tool accurately predicts non-invasiveness without falsely categorizing them as invasive. We developed a new Plant Risk Evaluation (PRE) tool for ornamental plants.

For the second year in a row, PlantRight has updated its list of suggested alternatives to horticultural invasive plants. This year-long process helps PlantRight focus its efforts on the highest priority invasives still for sale in the nursery trade. PlantRight wants to thank the many individuals who participated in the updating of this list by sharing feedback on their experiences across the state.

To check it out, click here!

In addition to a newly polished design, the new list has a few exciting changes. These include: improved information to help you choose the right noninvasive alternative for your needs; drought tolerant icons to highlight water wise plants; a paragraph highlighting “Why This Matters”; and five more plants have been retired as they are rarely found in the retail trade (sold at less than 1% of stores). For more information about the process and criteria for annually adding and removing plants, check out PlantRight’s FAQ page.

We look forward to using the latest list as a basis for engaging the horticultural supply chain about this important issue and opportunity. To learn more about how you can take advantage of shelf-ready materials to engage your horticultural community, consider completing PlantRight's brief Continuing Education program and becoming a PlantRight Ambassador.

You may have weeds and other plants that you consider invaders in your garden, but there are some ornamental plants that are far worse.

Jan Merryweather with PlantRight, a San Francisco-based nonprofit group that works with retailers to prevent invasive plants from making their way into our yards, says about half of the plants the group has identified as invasives were purchased innocently enough at area nurseries and garden centers...
