Invasive Plants? #940627

Asked July 27, 2026, 10:09 AM EDT

We have two shrubs growing on our property border that based on some preliminary investigation and the spread of the plants we believe that one is Autumn Olive and the other is Amur Honeysuckle. Can you possibility confirm this based on the pictures provided or should we bring in a sample cutting to the walk in office.

Hi, Anthony -

Thank you for reaching out to the UNH Extension Infoline!

It seems only one of your photos made it into the system here. That one does show autumn olive, with the leaves, stems and fruit clearly visible. It is considered invasive in New Hampshire, as you may already know. Here is some information on removal of autumn olive: https://extension.unh.edu/blog/2018/06/invasive-spotlight-autumn-olive and https://extension.unh.edu/blog/2018/06/invasive-spotlight-autumn-olive. For small infestations, mechanical removal can work. For large infestations, approved herbicides may be the best option.

If you could resend the photo of the honeysuckle, will take a look at it!

Thank you for contacting the Infoline, a service of UNH Cooperative Extension. Replied July 27, 2026, 1:03 PM EDT
