Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Topic: Invasive Plants
Title: Understory planting in Virginia
Answered by: Anne Bossart


We have some 10 mature tulip and sycamore trees in our No. VA property. The previous home owners were fond of English Ivy and Japanese pachysandra. We are working hard at replacing these invasives to encourage amphibians and birds to be permanent residents. Can you please provide understory trees and/or shrubs as well as perenial companions to these trees? I would also be interested in information about how to remove the pachysandra.


As you already know, the only way to eradicate tenacious vines and groundcovers is to be persistent.  As far as the pachysandra goes, there are three methods:  kill it chemically (not the Green Guru's recommended method!), covering it with black plastic to starve it of light and water (time consuming and unsightly) and digging it up (just plain hard work).  It has been suggested that the best way to achieve removal by digging is to post on the web that it is available for free to those who will dig it!

We applaud your efforts to welcome nature back to your property.  Visit the National Wildlife Federation's website at www.nwf.org/gardenforwildlife for tips on creating a wildlife habitat garden.  You will also find two books particularly helpful:  Rick Darke's "The American Woodland Garden" and Ken Druse's "The Natural Habitat Garden".  

You don't mention the size of your property, conditions (soil, moisture, light) or what type of neighbourhood you are in, but going on the assumption that conditions will be fairly shady and dry, here are some plant recommendations for Virginia.  If you visit our Plant Database and do a combination search for your area and conditions or search Recommended Species for Virginia you will find many more choices.  In the end, your choices will be limited by what is available in the nurseries in your area.

Acer pensylvanicum (striped maple)

Aesculus pavia (red buckeye)

Amelanchier canadensis (Canadian serviceberry)

Cercis canadensis (eastern redbud)
