EASTCHESTER, N.Y. (CBSNewYork) — A pretty little plant with no natural enemies is spreading south out of the northern suburbs toward New York City.
Naturalists are worried it could choke out native plants.
As invaders go the corydalis incisa is a benign looking plant with bright green leaves, purple pink flowers, migrating along the banks of the Bronx River.
“This is moving fast. It was first found in 2014, and now it’s continuous from here to the Bronx,” Professor Christina Andruk told CBS2’s Lou Young.
In Eastchester, researchers from Iona College are trying to figure out a way to stop the spread of the corydalis incisa or incised fumewort.
It’s an imported plant with no natural enemies or competitors.
