Thank you for contacting the UVM Master Gardener Helpline with your question about Jerusalem Artichokes.

I searched the Vermont Invasive Species website (https://www.vtinvasives.org/) and the Jerusalem Artichoke is not currently listed as invasive. Most likely because in some areas it is considered a native plant.

That being said, the Missouri Botanical Garden published an information sheet that does include the following caution: “Plants will spread in the garden, sometimes invasively, by rhizomes and self-seeding to form colonies. Once planted in garden areas, they are difficult to remove from the garden. Tiny pieces of tuber left in the soils will sprout. Plants are best sited in areas where spread into other valuable plantings will not occur. “ https://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=277201&isprofile=0&

If you have a spot on your property where you can control the plants spread the artichoke does have some redeeming qualities. The flowers will attract birds and other pollinators and the roots are considered a low glycemic alternative to potatoes as described in this article entitled “Jerusalem Artichoke” published by University of Florida Extension: https://gardeningsolutions.ifas.ufl.edu/plants/edibles/vegetables/jerusalem-artichoke/

You might also find this article that discusses a few different varieties of artichokes helpful:
