Achillea ageratifolia
This compact species makes a tufted mound of silvery leaves. Short stems carry crisp white daisies in late spring to early summer. It excels in sunny, dry positions with very good drainage and lean soils. Plants are suited to rock gardens, troughs, and the front of borders. Foliage may persist in winter where conditions are mild. Avoid heavy soils and excess moisture.
