Plant List of Native Alternatives to Invasive Species

Editor’s note: This is the third and final installment in a series about creating a bird-friendly yard. In the two previous blog articles, Wendy Diaz, EMGV, wrote about pivotal moments in her life as a gardener: deciding to focus on native plants, and creating a plan based on plant recommendations from the National Audobon Society.

My plan to create a bird-friendly yard will be accomplished in two stages. Stage 1 is the removal of high-threat invasive species in the fall of this year (2018), and Stage 2 will commence in the spring of 2019 by removing non-natives that are not high threat but their native alternatives would provide more benefit for wildlife and not multiply as quickly.

My garden  plan includes the following replacements based on recommendations from the New Hope Audubon Society, NC Botanical Garden and the Going Native Website1,2,3:

 Already Removed

Invasive Plant Native Alternative Plant
Mimosa (Albizia julibrissin) Magnolia (Magnolia grandiflora)
Bradford pear (Pyrus calleryana) Eastern Redbud (Cercis canadensis)
Chinese beauty berry (Callicarpa dichotoma) native beauty berry (Callicarpa  americana)
Autumn Olive (Elaeagnus umbellata) Maidenhair fern (Adiantum pedatum)
Japanese Stiltgrass (Microstegium vimineum) Sea Oats (Chasmanthium latifolium)

Stage I Removal of High Threat Invasive Species (Fall, 2018)

Invasive Plant Native Alternative Plant
Chinese wisteria (Wisteria sinensis) crossvine (Bignonia capreolata) or trumpet vine (Campsis radicanas) or Carolina jessamine (Gelsemium sempervirens) and Dwarf fothergilla (Fothergilla gardenii)
Big Leaf Periwinkle (Vinca major) spotted wintergreen (Chimaphila maculata), Frogfruit (Phylla nodiflora), Oakleaf hydrangea (Hydrangea quercifolia), Christmas Fern (Polystichum acrostichoides), Common blue violet (Viola sororia), Crested dwarf iris (Iris cristata)
Heavenly bamboo (Nandina) Florida-hobblebush (Agarista populifolia),  Strawberrybush (Euonymous americanus)/ St. Andrew’s Cross (Hypericum hypericoides)
Japanese honeysuckle (Lonicera japonica) coral honeysuckle (Loncicera sempervirens)/Yellow Passionflower (Passiflora lutea)
English Ivy (Hedera helix) Virginia Creeper (Parthenocissus quinquefolia)
Burning bush (Euonymus alatus) Virginia sweetspire (Itea virginica)/winterberry (Ilex verticillata) /winged sumac (Rhus copallinum)

Stage II Removal (Spring, 2019)

Non-Native Plant Native Alternative Plant
Golden Rain Tree (Koelreuteria paniculata) Black Locust (Robinia pseudoacacia)
Butterfly bush Coastal sweet-pepperbush (Clethra alnifolia)
Japanese privet common wax-myrtle (Morella cerifera)
Morning glory native clematis viorna (Clematis viorna)/milkvine (Matelea carolinensis)
Chinese holly Inkberry (Ilex glabra)/Eastern redcedar (Juniperus virginiana)/ Yaupon holly (Ilex vomitoria)
Forsythia Spicebush (Lindera benzoin)/high bush blueberry (Vaccinium corymbosum)
Grass Rosy Sedge (Carex rosea) and Pink muhly (Muhlenbergia capillaris)
Siberian Iris Scarlet rose-mallow (Hibiscus coccineus)
Liriope (Liriope muscari variegated) Bee balm (Monarda didyma)

Next time you are considering an ornamental plant to add to your landscape why not try a native plant that suits your needs and helps wildlife at the same time? At the very least, don’t plant invasive species like I did. Hopefully in time, I will attract new birds, butterflies and caterpillars. Then I will need a better camera lens to zoom in on all the new flowers and animals!

Planning a Bird-friendly Yard

Editor’s note: This is the second post in a series about bird-friendly native gardening written by Wendy Diaz, EMGV. The third and final post, a plant list, will appear next week.

After a visit to my yard by representatives from the New Hope Audubon Society, I resolved to rid my garden of invasive species. My goal is to achieve Platinum Certification and, consequently, invasive plants cannot cover more than 10% of my property; an improvement from the Gold Level I received in August. A helpful guide on how to plan and implement a more bird-friendly yard, by selecting native plants that suit your needs as well as birds, is provided by the Going Native website1. A particularly useful tool is the plant selection guide that helps you select plants that fit your gardening needs and conditions so you can make your own plant list2.  A native plant is suggested just by entering your region, light requirement, soil moisture, leaf type, wildlife value target and bloom period.

This fall, the first plant to be removed is my non-flowering Chinese wisteria that I will probably replace with Audubon’s suggestion of a crossvine or trumpet vine. The second plant that I will take on will be the Big Leaf Periwinkle (Vinca major). About 1,000 square feet of my yard, beneath my hardwoods is covered with Big Leaf Periwinkle so I plan on using several plants to replace this ground cover in the part shady area with varying degrees of soil moisture. This will also increase the diversity of plants in my yard and year-round color interest. It is relatively easy to pull the Vinca major up by the roots, although they recommended mowing it first, because of the abundance of rain this year. Although I have already removed the Mimosa and Bradford Pear trees years ago, their former presence is evident by the frequent seedlings that still germinate in my yard, so this effort of eradication will require ongoing vigilance.

Planting of the alternative native plants will occur gradually over time as I source the plants from area nurseries, optimize my budget and observe the plants’ performance ornamentally and ecologically. I already have some of the native plants and I will encourage them to spread and may propagate them.
