Hi Joanne,

Thank you for reaching out to us at the UNH Extension Infoline.

Wild bergamot (Monarda fistulosa) is not on the official NH invasive plants list: https://www.agriculture.nh.gov/publications-forms/documents/nh-invasive-plant-list.pdf

However, wild bergamot can definitely have invasive-like growth habits with it being a member of the mint family. If you've planted yours in an area where it is content, it will thrive and potentially grow/spread more than you'd like

If you're hoping to find plants that will attract a wide range of pollinators (including hummingbirds - they love wild bergamot!), here is a list from UNH Extension: https://extension.unh.edu/resource/pollinator-plants-northern-new-england-gardens-fact-sheet Wild bergamot is listed alongside many others!

Have a great day. Please reach out if you have any further questions!
