Achillea species - Yarrow and Sneezewort
Achillea millefolium, Yarrow, has leaves which are lanceolate in outline, but are finely divided 2 - 3 pinnate. The plant is aromatic when crushed. The umbel of many small flowers is usually white, but can be pink.
Achillea ptarmica, Sneezewort, has larger flowers than Achillea millefolium, but the main difference is the finely-toothed but otherwise entire leaves. It is found in wetter areas.
