Letter: Barberry not good choice for landscapes

I have enjoyed the articles The Gazette has published about how homeowners can help pollinators. I was therefore dismayed to read an article in the April 10 Gazette ('Digging in”) that recommended using invasive plant species in home landscapes. Of greatest concern was the suggestion to plant Japanese barberry (Berberis thunbergii).

Yes, landscapers are fond of using barberry because it is hardy and easy to maintain. But homeowners need to know that barberry is also very invasive in our woodlands. As you drive along East Post Road, take note of the low-growing green shrubs in the woods on either side of the road. What you might think is a welcome sign of spring is actually proof of how extensively this invasive shrub is overtaking our native woodlands. Birds spread this plant by feeding on its berries. But it can also spread through its roots and forms dense clumps in our woodlands. It crowds out desirable native woodland plants and native tree seedlings.

Japanese barberry also alters soil structure and soil chemistry, making it impossible for other plant species to survive. Yes, homeowners should do their homework before landscaping, and if they care about the health of our woodlands and the pollinators and other wildlife that depend on them, they will choose to plant a diversity of native plants. Even better, they will tell nurseries and landscapers they are not interested in planting Japanese barberry or other invasive plants.
