Invasive plants are introduced species that can thrive in areas beyond their natural range of dispersal. These plants are characteristically adaptable, aggressive, and have a high reproductive capacity.

Canadian goldenrod is an allergenic plant. Canada goldenrod is a perennial distinguished by numerous small yellow flowers located in pyramid-shaped clusters at the top of individual, unbranched, leafy stems.  This species spreading in the meadow and riparian ecosystems violates the structure of crops, which leads to oppression and even complete displacement of native plants.
