Beware the Invasive Species

Some of the most noteworthy invasive plants

Invading extraterrestrial aliens are bad enough, but invasive species of the plant variety are not to be taken lightly either, at least according to the Invasive Weeds Awareness Coalition (IWAC). While most exotic plants are not a problem, the IWAC warns to be careful about selecting or planting nonnative plants, as some become invasive and can eventually destroy habitat that sustains native birds, butterflies, insects and small animals.

Mary Meyer, PhD, a horticulturalist and associate professor at the University of Minnesota in St. Paul, notes that most garden centers are careful not to carry invasive species, but every year new species turn up. She advises asking the local extension service before choosing a nonnative plant.

The most serious invaders include: purple loosestrife; Russian olive; saltcedar; buckthorn; English ivy; and water hyacinth.
