Is anyone able to identify this plant, please. I'm pretty sure it's a variety of Tanacetum.
It's growing in my South facing garden and produces bright yellow late Spring flowers, although I tend to cut them off as I prefer the foliage on it's own.
Any suggestions will be very welcome. I've had the plant for nearly 20 years and have been unable to give it a full name.

Maybe Tansy (Tanacetum vulgare)

It definitely isn't a Tansy, but thank you for your attempt to identify it.

I agree that it isn't tansy -- does it flower, Trish?

Hello, Sandy,
Yes it has rather non-descipt yellow flowers in late Spring, quite tatty looking so I cut them off and enjoy the foliage

Hi,
You feel this is in the TANACETUM FAMILY.
Tansy is the common name for plants in the Tanacetum family. I believe this is an ornamental perennial in my area, I am searching. Are Tansy invasive in your area?

Tanacetum crispum?

Tansy (Tanacetum vulgare 'Crispum')

Or perhaps a variety of Senecio or Jacobaea? One for comparison: Tansy Ragwort (Jacobaea vulgaris)

The description of tatty flowers made me think of Dusty Miller (Jacobaea maritima subsp. maritima) the leaves don't match for that one.

Hello, Laurie, Janine and Lin,

Thank you for your suggestions, none of which fit the description of the plant in my garden unfortunately.
Tansy, as a wild flower, is quite rare in North Yorkshire. The one I am trying to identify is definitely an ornamental garden perennial.

I may be totally wrong in thinking it is Tanacetum, but that's what the foliage reminds me of.

I'm rushing this but it looks a little like achillea clypeolata but I really don't have a good photo comparison.

Hi Loretta,

Thank you for your suggestion, but it definitely not Achillea clypeolata.

It might be helpful if you described the flowers a little better.

As I mentioned earlier, the yellow flowers are quite untidy. They are like a small daisy growing about 2-3" above the foliage on woody stems

So a flower with a center disk and rays.
I keep thinking I know this plant but I think it is looking familiar to me is because it looks so much like my oriental poppy, Victoria Louise, which of course, it is not.

Does the foliage have any scent? Could it be an Anthemis of some kind?

Yes, the foliage is slightly aromatic, not as strong as an Anthemis I have though.

Interesting.
Have had a good go to id this with no joy.

When did you take those pics?
How tall is it?
Is it deciduous ot evergreen.?
Is it woody at the base?

Maybe we will need to wait for next year and pics to show the flowers.

The picture was taken early Summer.
It's about 6" tall and has a spread of around 12"
Evergreen with a woody base.

I appreciate everyone's help, as I mentioned at the start it's been a puzzle to me for years and as I work with plants I really should know it!

Well, if nothing comes of this, you must post the flower in the spring as we all want to know now and a clear photo of the leaf margins.
Here are some links to Yarrow Moonshine which is as close as I've found so far even though I know you say it isn't a yarrow but maybe it will spark something. Is the plant present now?

I am still trying to indentify this plant. These photos were taken 16/02/18. The plant has held it's semi-wooden state throughout winter, and recent frost and snow hasn't damaged the youngest foliage. The old foliage dropped in Autumn.
If anyone is able to help I shall be very grateful. I'll post another photo when the flowers appear in Spring.
