Take a moment to read this post and fill out the quick survey. Just a few days left until the deadline. đ
Do you think certain introduced plants should no longer be offered for sale?
A new proposal would add six common landscaping plants (Common buckthorn, glossy buckthorn, callery (Bradford) pear, Japanese barberry, water hyacinth and water lettuce) to Michiganâs Restricted and Prohibited list, making it illegal to introduce, import, transplant, sell, or intentionally possess them in Michigan (a person wouldnât be considered in violation of the rules if they unknowingly have these plants established on their property).
MI Dept. of Agriculture and Rural Development is asking for public comment. If you have an opinion, please fill out this short survey by February 9.

These species were brought to North America by landscapers as ornamental gardening plants. They are all part of a balanced ecosystem in their native environments where, like any other plant, their populations are controlled by diseases, insect predators, and plant competitors. But those checks donât exist here in Michigan, so the introduced plants have escaped the confines of yards and mall parking lots and now reproduce freely in natural areas, outcompeting the native plants that didnât evolve with them but still face their own checks and balances.
The spread of these introduced plants is harming Michiganâs natural habitats. When they dominate an open field, woodland or lake, they crowd out the native plants that wildlife depend on: insects canât find the right food plants for their larvae, birds that depend on those insect larvae canât feed their babies, and deer eat all of the remaining native plants because they donât like the taste of the newcomers.
We canât help but be biased in our opinion about curbing the sale of these plants in Michigan: when we talk about ârestoring habitats,â these are the very plants SWMLCâs Stewardship department is trying to control!
