Just wondering if this is a Feverfew or something else. It surfaced in our garden last year and has doubled in size/area this year. A neighbour suggested that it's feverfew but I think the flower looks a little different. Thanks!
There are semi-double and double Tanacetum parthenium cultivars available which look like yours. The fact that it doubled in size/area in your garden this year should give you some indication of its intentions. It isn't difficult to keep in check if you like it and would enjoy limited numbers of plants. Deadheading or pulling excess plants is key to keeping it under control.
Thanks very much! We'll be pulling a few excess plants this summer. They do seem to spread like a weed.
