The Michigan Department of Agriculture and Rural Development may add six new plant species to the state’s list of invasive plants. This list could include Callery pear, Japanese barberry, and two aquatic plants.

If approved, water hyacinth and water lettuce would be considered illegal to sell or transport 30 days after they are officially listed. The Callery pear, common buckthorn, glossy buckthorn, and Japanese barberry would become restricted starting January 1, 2028. These regulations would prevent the sale or purchase of these plants but would not impact property owners who already possess them.

Officials state that these plants can pose risks to Michigan’s environment, economy, and public health. They have the potential to displace native species, damage infrastructure, and in some cases, host ticks that carry diseases.
