Plant NOVA Natives! Why are native plants important? How do I select native plants? Where can I buy native plants?

Marketing Native Plants – a statewide campaign
“Plant NoVA Natives is a new campaign that brings together the Northern Virginia Regional Commission, local chapters of the Virginia Native Plant Society, nurseries, and other groups, creating a website, guidebook, workshop series and plant tags to be used in local garden stores.”

The Plant NoVA Natives campaign aims to get the word out more consistently on the benefits of native plants and also will help you identify them.
Watch out for their trumpet honeysuckle and sphinx moth logo on plant tags in the marketplace!


The goals of the plant NoVA Natives campaign are:

  • to raise awareness on the issues surrounding native plants
  • to establish a social norm to increase the use of native plants

Native plants and habitats in our Chesapeake area

  • sustain biodiversity
  • provide habitat for wildlife including pollinators
  • help achieve Chesapeake stormwater goals

The March 27, Plant NoVA Natives campaign event at Fairlington Community Center was well- attended by over seventy people, many of whom are Master Gardeners, Master Naturalists, and members of Audubon, Virginia Native Plant Society and other conservation groups. 

The Plant NoVA Natives campaign was introduced by Corey Miles (Planner at Northern Virginia Regional Commission), followed by excellent presentations by Jim McGlone (Urban Forest Conservationist, VA Dept of Forestry), Alan Ford (Potowmack Chapter President, Virginia Native Plant Society), and Judy Fraser (Program Developer, George Mason University Sustainability Institute).

Margaret Hawkins gave an overview of the Master Gardeners of Northern Virginia  (MGNV) Sustainable Landscapes program and team led by Carol Rosen and Kirsten Buhls (Agriculture and Natural Resources Agent, Virginia Cooperative Extension, Arlington office).

Landscape for Life: Making Your Yard Sustainable
In 2013 and 2014, Master Gardeners of Northern Virginia (MGNV) hosted Making Your Yard Sustainable 6-week workshops based on the national US Botanic Garden’s  Landscape for Life program.  Over 50 home and condo owners in Arlington and Alexandria have participated in these MGNV workshops that teach the principles of sustainable landscape design and how to use native plantings.  These are participants main questions:

  • What are the native plants that grow well here in our suburban and urban environment?
  • What native plants go well together?
  • Where can I buy native plants?

Tried and True – Native Plant Factsheets
In response to residents asking for more information on native plants, Master Gardeners of Northern Virginia have now assembled over 100 factsheets of Tried and True natives that thrive in this area.  Find the Tried and True online
The factsheets also list where the native plants can be found in the Arlington County and Alexandria City Demonstration Gardens.

Best Bets  Native Plant selections and groupings
In response to further demand from residents, MGNV are producing Best Bets factsheets that show how to select and group native plants to thrive in different conditions such as shade, sun, wet or dry.

Demonstration Gardens in Arlington and Alexandria
Master Gardeners of Northern Virginia maintain several demonstration gardens in Arlington and Alexandria. These demonstration gardens are in the process of being labeled using QR Codes linked to the Tried and True and Best Bet factsheets. The QR Code labeling is a work in progress.  Check back frequently as you visit these gardens over the next year or two to get inspiration for your own garden or another community or school garden.

The Flora of Virginia – What Are Our Native Plants?

This week native plants and flowers are the theme of two excellent programs hosted at the Fairlington Community Center.

The Flora of Virginia Project
Our first program is a workshop presented by Professor Marion Lobstein as Continuing Education/Advanced Training for Master Gardeners and Master Naturalists on the theme of The Flora of Virginia – the native flowering plants of Virginia.

As if I am in undergrad Botany Class, I listen and take notes as Marion Lobstein, Professor Emeritus at Northern Virginia Community College and Vice President of the Foundation of The Flora of Virginia Project sets the stage for her presentation of the latest research and recording of the wealth of flowering plants currently native or naturalized in Virginia.

First question: What is a “native plant”?
A “native plant” can be defined in several different ways.  It is a fuzzy and messy definition. Generally a “native plant” in Virginia is defined as being a plant that was here in the “New World” prior to Columbus’s arrival.  But before Columbus arrived native americans and wildlife moved around the land changing their habitat, and so inevitably did seeds and plants. These native plants co-evolved with other species, as other factors such as climate and geology also played their parts. So there is no static compilation of what comprised the “native plant” flora prior to Columbus. “Naturalized” plants are plants that come from other places that thrive being part of our local plant community, this is as opposed to “exotic invasive plants” that threaten to “takeover” or reduce a community’s  biodiversity

Marion continues “Did you all know: Virginia has the greatest diversity of native flowering plants compared to its size in the 50 US states?”  No, I had no idea.  But why does Virginia have so many kinds of native plants compared to other states?  Virginia has a very diverse geology and was situated at the intersection of glacial retreats and flows. Virginia is now the “mixing bowl” of “northern” and “southern” types of plant species with over 3200+ species in 198 families. Marion then shares the highlights of her research team and colleagues.  Their work and scholarship during the 11-year Flora of Virginia Project has recently culminated in the published handbook The Flora of Virginia. No wonder this comprehensive Flora of Virginia book weighs in at over three pounds!

Joanne Hutton introduces Professor Marion Lobstein

Marion challenges us, “But how to use this enormous book?”  I thumb through an introduction to plant classification and sections on the geology and ecology of Virginia.  There’s a history of plant discoverers.  And an appealing section for the armchair tourist or the active plant seeker on the hotspots for Virginia flora: the 50 best spots for field botany. Marion tells us about recent taxonomic or classification changes reflected in the book, that have been brought about by research on DNA genetic analysis.  For example, milkweeds are now classified with dogbanes and both families have partially-fused ovaries. We laugh.  And I learn that the native wild ginger is a very ancient plant.  Our native magnolias are also ancient flowering plants on the evolutionary path in the fossil record and do not quite fit the “monocot or dicot” dichotomy of later flowering plants. 

Then we learn the skills to use the Flora of Virginia to “key out” and identify native and naturalized plants. We “key out” Queen Anne’s Lace and Daffodils (both naturalized wild flowers in parts of Virginia).

Looking up Daffodil in the Flora of Virginia

I leave the workshop grateful to Marion for bringing the Flora to life with enthusiasm and humor  – and appreciative of the diversity of Virginia’s native and naturalized flowering plants.

Have You Seen This Bug? Look Out for Kudzu Bugs and Report Sightings

Cooperative Extension in Arlington is participating in a statewide survey to determine the presence of Kudzu Bugs in Northern Virginia.  Traps will be installed in suitable garden sites to try to detect their presence. If you see this insect at your home or elsewhere please report it to the Arlington Virginia Cooperative Extension Horticulture Help Desk at 703 228 6414 or email to  And if you have further questions, please contact Kirsten Buhls, Arlington’s Agriculture and Natural Resources agent,, 703 228 6423.

Glencarlyn Library Demonstration Garden in Arlington is part of statewide research being conducted by Virginia Tech that seeks to track the spread of the invasive Kudzu Bug into Northern Virginia.  For the next 6-8 weeks VCE Master Gardeners will be checking a white bug trap in the library garden to see if we find this bug here in Arlington.

Background to Kudzu Bugs
In October 2009, large aggregations of Kudzu Bug (Megacopta cribraria (F.); Heteroptera: Plataspidae), also known as bean plataspid, lablab bug, or globular stink bug, were discovered on the exterior of houses in nine northeast Georgia counties.


Also see these two 3-minute videos about Kudzu Bugs in Spanish
or in English

By 2010,  Kudzu Bug was confirmed in more than 60 Georgia counties.  This insect that is native to Asia feeds on kudzu, wisteria, and other members of the bean family.  It has become a serious pest of soybean crop fields as far north as 21 counties in Virginia and 3 southern Maryland counties.

Megacopta cribraria is related to the brown marmorated stink bug.  Adult Kudzu Bugs are 4 to 6 mm long, oblong, olive-green colored with brown speckles, and produce a mildly offensive odor when disturbed.
In its native Asia, one of M. cribraria’s preferred hosts is kudzu, an invasive vine introduced into the U.S. more than 100 years ago.  While the good news is that the invasive vine Kudzu appears to be a primary host in North America, M. cribraria is expected to spread into most areas where kudzu is established.   The bigger concern is that this insect will become another nuisance pest. Similar to behavior of brown marmorated stink bugs, kudzu bugs seek secluded sites like the inside of your home as temperatures fall and daylengths shorten in the fall.  They overwinter as adults and emerge in the spring, as temperatures increase,

Control of M. cribraria consists of the following:

Exclusion: place screening over any possible entries into house and ensure that they are tight and well seated, without holes. Be sure to screen soffit, ridge and gable vents. Stuff steel wool into pipe entry points and make sure that all doors are tight fitting.   Kudzu bugs on a window frame. Photo courtesy

Insecticide: The insects congregate on sunny south facing outdoor walls in the fall and insecticide applications can be made to stop this.   Consult with a certified pesticide applicator who has the equipment needed for broadside applications of nuisance insect control products. Repeat applications may be needed but microencapsulated and wettable powder formulations will last longer. Indoor pesticide applications for M. cribraria are not recommended.

Mechanical:  Vacuum and bag insects, gather them and place in hot soapy water, avoid crushing them as long lasting odors and staining of surfaces may result.

Biological:  Encourage natural predators by planting a wide variety of plants.  Assassin bugs are known to feed on M. cribraria, and other native predators may emerge.  Removal of  source plantings like kudzu and wisteria can reduce numbers of bugs in your vicinity.
