Cream flowered sneezewort

Achillea odorata, the cream-flowered sneezewort or scented yarrow, is a small aromatic perennial herb in the Asteraceae native to dry, calcareous grasslands, garrigue, and rocky slopes of the western Mediterranean basin, including Spain, southern France, Italy, and North Africa. Plants form low, leafy, mat-like clumps from short, branching rhizomes and reach only 10 to 30 cm tall in flower, well below typical Achillea millefolium. The alternate leaves are oblong-lanceolate in outline, 2 to 5 cm long, twice to three times pinnatifid into very narrow, almost filiform ultimate segments crowded along the rachis, finely greyish-pubescent, and emitting a strong sweet, somewhat camphoraceous aroma when crushed. The flat-topped to slightly domed corymb is composed of 15 to 50 small composite heads, each 4 to 6 mm across, with 5 to 8 short, broad, creamy white to pale yellowish ray florets and yellow disc florets. Achenes are small, glabrous, oblong, and lack a pappus.
