Question
The plant I've photographed appeared as if intentionally planted in our semi-shade back garden this spring. Foliage like fennel, no fragrance, 3'tall and now producing daisy like flowers. My i.d. from simple key:Tripleurospermum inodorum. Will it become invasive if I leave it, or should I get rid of the plant now?
Answer
Dear HostaHeuchera2, from what I can tell from the images, it does look like you have photographed Tripleurospermum inodorum. While these plants are "weedy", I rarely see them being aggressive in New England. Whether or not you leave it depends on your personal taste and how much you enjoy its presence. Best wishes.
