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.

Title: Plants to filter dust from a road in MD
Answered by: Anne Bossart

QUESTION:

I live in MD next to a dirt/gravel access road. I would like to plant something along my property line to block the clouds of dust we regularly get from cars and dirt bikes. Is there something fast growing and low maintenance that I can plant there? Thank you.

ANSWER:

The fastest growing and lowest maintenance plants are without question, large deciduous shrubs or small multistemmed trees.  They can take the abuse they receive next to a dirt road, put on a fresh coat of leaves every spring and have flowers and fruit to attract birds (and humans).

To begin the plant selection process you can search our Native Plant Database.  Do a Combination Search for Maryland, selecting: shrubs or trees/your conditions and size (6-12 feet or larger).  It will generate a list with links to detailed plant information pages.

Here are some small trees to consider:

Amelanchier laevis (Allegheny service-berry)

Cercis canadensis (Eastern redbud)

Cornus drummondii (Roughleaf dogwood)

Rhus typhina (Staghorn sumac)

Sassafras albidum (Sassafras)

and some large shrubs:

Calycanthus floridus (Eastern sweetshrub)

Clethra alnifolia (Coastal sweet pepperbush)

Ilex glabra (Inkberry)

Physocarpus opulifolius (Atlantic ninebark)

Viburnum dentatum (Southern arrowwood)

Viburnum opulus var. americanum (American cranberry bush)

 

Using a combination of these plants you could have a "hedgerow" with flowers in spring and summer, fall colour, summer fragrance and the wildlife benefits of cover and food.  Plus it would meet the practical requirements of your situation.
