“There’s been a movement in recent years toward the belief that non-native plants are an ecological threat but this isn’t true in all instances. An educated use of non-natives can add diversity, ornamental interest, and value to any landscape. One example is the Japanese Stewartia. To many landscape architects it’s a connoisseur’s plant.”
The Stewartia grows well in New Jersey, and Kristoph has planted it many times. “There’s a need for non-native plants,” he says. “Not all of them are invasive and troublesome.”
Kristoph will be teaching two courses at Rutgers in the month of July: “The Woody Plants of Summer: Native Plants” on July 25 and “The Woody Plants of Summer: Non-Native Plants” on July 31. Both classes involve a brief lecture followed by an outdoor walk where students will view specimens. You can still sign up for both courses.

I am a garden writer and want to write about this in my weekly column for our local newspaper.. Thanks for raising an issue that’s really been bothering me. First, to blame all nonnative plants for the bad habits of some isn’t fair. But more important, what’s always missing in this discussion is the overwhelmingly negative impact of industrial agriculture. Asking homeowners to bear the burden of offsetting the effects of what Big Ag does to the planet is impractical and also misleading because it’s impossible. We CAN’T offset those impacts. And attempting to is really just a distraction from the more important fight, unless the effort itself raises awareness of the larger problem.
