which daisy?
This was seen growing, apparently spontaneously, at the edge of a garden
access road. My best guess is sneezewort (Achillea ptarmica), but it doesn't seem quite right - the habit is too compact, and the leaves too short. Any other offers. http://www.stewart.hinsley.me.uk/Images/Compos06.jpg The other leaves in the photograph are Solanum nigrum. -- Stewart Robert Hinsley |

There is a possibility that it's a seedling of a garden variety growing in adverse circumstances. Following that thought, I've done a google image search and more or less convinced myself that it is indeed sneezewort. |

We had something in West Wales which I was /sure/ was sneezewort, but it was lightly and pleasantly aromatic; but since the Collins Field Guide explicitly said it was "not aromatic", in Italics, I assume this is a diagnostic character, which implies a similar species I don't know about. But I'm wondering if there may be more varieties or forms of A. ptarmica than are recognised (at least by the Guide: I haven't anything more advanced). -- Mike. |

Unfortunately, I didn't think to check that feature. We had something in West Wales which I was /sure/ was sneezewort, but it was lightly and pleasantly aromatic; but since the Collins Field Guide explicitly said it was "not aromatic", in Italics, I assume this is a diagnostic character, which implies a similar species I don't know about. But I'm wondering if there may be more varieties or forms of A. ptarmica than are recognised (at least by the Guide: I haven't anything more advanced). But you've jogged my memory. There's a plant known as Sweet Nancy or English Mace (Achillea ageratum syn decolorans syn serrata), not mentioned in the 1st edition of Stace, but with 3 records from Great Britain, which from a photograph I took on a visit to Cumbria has similar foliage. (It wasn't flowering at the time.) Digging around the web I find some confusion - the name Achillea ageratum is applied both to a plant with yellow discoid capitula, and white radiate capitula. Achillea decolorans and Achillea serrata appear to only be associated with the latter. There are other white-flowered Achilleas, but I'm not finding a match. For all I know it may be Achillea ptarmica. -- Stewart Robert Hinsley |
