Why native plants?

As a Master Gardener I've learned about the role of our plant choices in home gardens to preserve habitat.  Though our part of the world often looks very green, the diversity and quality of plant habitat is in decline.  Most of our wooded areas, for example, are full of invasive species replacing the native undergrowth.   If each of us tries to plant natives -- canopy trees, understory trees, shrubs, perennials and groundcover -- we can help the butterflies, birds and other marvelous creatures who share our part of the world. 

The photo above by LDS earth steward Ralph Johnson illustrates one benefit of native plants. During winter months berries and nuts from native trees and shrubs provide food for many creatures. Consider adding winter interest for your garden as well as habitat. Here’s a list of just a few of the beautiful choices for our area: https://www.chesapeakebay.net/news/blog/nine_native_chesapeake_bay_plants_that_look_beautiful_in_winter


Why plant a native tree?  Here's just one example.  The native dogwood (Cornus florda) supports 117 species of native moths and butterflies.   The Asian dogwood (Cornus kousa) supports no native insect herbivores (from Dr. Doug Tallamy, University of Delaware entomologist).  Often there are very complex relationships between plants and insects, birds and other animals.  One family of baby Carolina chickadees requires about 6,000 caterpillars. Birdseed that people put out is of no use for baby birds — they need the protein from caterpillars and other bugs. When a native plant is no longer growing in an area, creatures dependent on that plant are also lost.  The web of life unravels.

Photos above show native dogwoods in bloom and in fall. This beautiful native tree is available in various white and pink cultivars as well as the straight species.  It's just one of hundreds of native trees for our area that are readily available in nurseries. Native trees are currently available for free in Montgomery County through several programs including:

If you want to buy a native tree you can get discounts at participating nurseries. Download a coupon to receive $25 off. On residential properties in Montgomery County, the Maryland coupon can be combined with the Leaves for Neighborhoods coupon to receive $40 off the purchase of a native tree with a retail value of at least $75 at participating nurseries. 

It’s likely there are incentive programs in your area if you live outside Maryland to plant native trees. In DC there’s a program for $50 or $100 rebates depending on the tree species through Casey Trees. https://caseytrees.org/resources/tree-rebate/

Getting Started

Match the right plant to the right place. 

If you have a space that is small or large, shady or full sun, soggy or dry there's a native plant that can and will take root if you give it a chance. From trees (large and small), shrubs, perennials, vines, ground covers, these plants will fit the conditions of the area because they are adapted to the weather, pests, soil, and seasons of Eastern North America.   They provide habitat for insects and other creatures which have co-evolved often over millions of years in intricate relationships. This is why replacing extensive areas of non-native turf grass with native plants can be so beneficial.  The key to a healthy, thriving garden:  choose plants that want what you have to give (full sun, part sun, part shade, deep shade; dry, medium, damp, wet soil; sand, loam, clay).  I've killed plenty of native plants by ignoring this basic principle: match the right plant to the right place. 

Take Action

Reduce lawn by adding or extending beds. Remove invasive plants. If you have woods, increase native understory and ground cover and add native shrubs and perennials at the edge.  Use diverse native plants but also include large groups of each plant type, if possible.  This makes sense -- if you're providing habitat you need enough of a single plant to make it worth the pollinators' and others time to visit or live in your garden. You don't need to dig out turf or use Roundup -- just cover the turf with overlapping cardboard or thick sections of newspaper (overlapping at least 6"). Cover with a layer of aged compost and top with mulch.  Do this in the fall and the area will be ready to plant the following spring. In a hurry? Do as described above but using a sharp spade (pointed shovel) cut through the cardboard and turf to dig holes for shrubs and trees as you create the bed. These plants can get established over the first winter and by spring you can add in the rest of the plants.

Some Favorites

The photos show some easily grown and readily available native plants that are my favorites.  Just a tiny fraction of what's available.  Below the photos are online resources, books, and native plant gardens where you can learn more about the fabulous plants of our region.

Extensive native plant garden near Wilmington, DE which does 3-year trials of many species and cultivars of native plants used in gardens.  Plants are assessed on vigor, flower profusion, disease resistance, and insect visits.  Recent published trials include monarda, baptisia, coreopsis, asters, coneflowers and more.  Upcoming trials include garden phlox, helenium, amsonia, hydrangea and clematis.  (See photos of Mt. Cuba on eartheast.org under the heading "Trails & Natural Areas".)

Some Native Plant Sources  

Often other gardeners are generous with plants and will share plant divisions and seed if asked. Native plant sales (below) are a great source and increasingly general nurseries carry native plants.

Local nurseries: Plants tagged as native may not be locally native, check. Ask for the source of the plant.  Buy nursery propagated vs. nursery grown (may have been wild collected).  Don't collect from the wild yourself unless the area is going to be destroyed and plants need to be rescued.

Lists native plant sales held throughout the year.  These sales are often the best source for local, native plants.  A few particularly good native plant sales are listed below.

Native plant gardens

Pleasant View Historic Site.  Our very own native plant garden begun in April 2017.  This site is open to the public.  Come see what Earth Stewardship East along with community volunteers has been able to create.  11810 Darnestown Road, Gaithersburg, MD. We spent $500+ on plant tags so you could come and learn about native plants. We're also hosting free talks on creating conservation landscaping. Contact merikays@verizon.net if you're interested.

National Arboretum.  In the past this has been more an interesting place to see diverse non-native plants but displays have increasingly included natives.  Of particular note is the fern valley collection.  Ask at the info desk for directions to areas with native plants.  Free and open every day except Dec. 25.

National Botanic Gardens.  The three-acre National Garden draws inspiration from the environments of the Mid-Atlantic region. Conceived as an outdoor laboratory for gardening in harmony with natural ecosystems, the Garden opened in the fall of 2006 next to the Conservatory.  Free parking is available on weekends - in front of the Capitol building.  A great place to get native plant ideas -- I like to visit in different seasons.  Not all plants are native but many are.  Website shows photos of many plants and descriptions.



Mt. Cuba Center.  This massive native plant garden near Wilmington, DE is worth a visit if you're in the area.  Open April - November from 10 am to 4 pm on Wednesday - Sunday.  Modest admission fee.  Formal gardens, woodland trails, wetland garden, meadow trail.  Trial garden of particular interest.  Their native plant trial reports a must-read to know about the best cultivars/species of the plants trialed.  The reports give useful historical and cultivation information, photographs and plant recommendations.
