While driving around this week keep a look out for all the white flowering trees scattered among just about every “natural” and unnatural area in our city. This is a perfect example of the dangers of invasive species and why planting native to our region is so important. The tree I am referring to is the dreaded Bradford Pear (Pyrus calleryana).
At one time the Bradford Pear was widely planted all around the city because of its modest size, adaptability, and early spring blooms. Unfortunately the tree has weak limbs which break during storms, horrible smelling flowers, and is as invasive as can be. They out compete most of our native under story trees such as Redbuds and Dogwoods and provide little if any ecological value. Fortunately, the planting of Bradford Pears greatly decreased once the negative attributes were discovered, however the damage is already done.
Let this example be a catalyst to encourage ourselves and others to recognize the negative impact non native invasive plants have on our environment. With the plethora of native trees, shrubs, and perennials available, finding beneficial alternatives to non-natives is easier than ever.
If you are in the Richmond area and would like to purchase native plants, check out Plant by Design Native Nursery . We are currently offering a selection of perennials native to our region and will be adding shrubs and trees in the near future. Plants will be available for purchase at Siteone (Formerly Glen Allen Nursery) and Elwood Thompson’s this April.
Last post we discussed the removal of an invasive non-native known as Euphorbia amygdaloides. We got several requests to name ground covers to stay away from and also native options to use instead.
So here’s a quick list:
DO NOT PLANT: (No matter what your local nursery says!)
- Vinca minor (Perrie winkle)
- Vinca major
- English ivy (Shown in picture above)
- Spicata liriope (Or any liriope for that matter)
- Ajuga (Some varieties tend to be easier to keep in check so we aren’t totally against this one)
- Houttuynia cordata (Chameleon plant) – You will hate yourself forever if you plant this one. It is literally impossible to get rid of. Why would anyone still sell this???
- Clematis terniflora (Sweet Autumn Clematis) – We spent all day today removing this one from a residence on Grace St. It will take several more years to eradicate it.
- Euyonomus fortunei (Winter creeper)
GREAT NATIVE GROUND COVERS: (Let us know if you need help locating any of these)
- Chrysogonum virginianum (Green and Gold…shown above)
- Meehania cordata (Meehans mint… a great substitute for ajuga)
- Pachysandra procumbens (Don’t confuse this with the non-native pachysandra sold at most garden centers)
- Lindernia grandiflora (A great choice for planting between stepping stones)
- Clematis virginiana (Similar to terniflora but native and less aggressive)
- Callirhoe Involucrata (Wine cup)
- Carex pensylvanica (No need to plant liriope when we have this great native)
- Phlox subulata
- Phlox stolonifera
- Phlox divaricata
- Aster divaricatus
To sum things up, we at Plant by Design are not purists. We do believe that planting some non-natives in your landscape is perfectly fine. The issue comes when the non-natives are more aggressive and out compete our local flora. The ground covers we have asked you not to plant are invasive. While walking through the woods its hard not to find Vinca or Ivy choking out our native plants. Do not be afraid to mention this next time you are shopping at your local garden center. We never fault the home owner, we fault the garden centers that should be more responsible with the plants they sell.
