Hi Rich
I did a search with Google under Images with:

Tenacetum parthenium "Magic Lime Green" and I cam up with a picture of the feverfew, you can try it yourself to see it. There is not much information on it. only a picture.

Hi Wildflower;
I did search Google and I tried it again after reading your post. No luck. If you find it again can you post the link?
Thanks
Rich

Here's a photo, Rich. The page is translated from German.

Here is a link that might be useful: Magic Lime Green feverfew

cailinriley; Thank you for posting the link for Magic Lime. I have to have that flower. I'm trying to contact PanAmerican Seed to see if they can help as it look like the picture is from their gardens. They don't sell to the public but maybe they can tell me who has that plant. Thanks again.
Rich
