Achillea kellereri * Keller's Yarrow

Narrow finely divided leaves of Achillea kellereri make the plant interesting even when it is not blooming. Achillea kellereri is a little stronger in the garden than Achillea clavennae which is similar in its uses. The difference is in the width and texture of the leaves. The leaves are broader in A. clavinnae and closer to the ground. The fragrant foliage is about 4-6" tall and gradually expands in width over the years. Keller's Yarrow white flowers grow on stalks up to 8" tall. A summer repeat bloom can be encouraged by deadheading the fading flowers. I have used them in the landscape much as one would use the gray fescue, Festuca ovina. Because they stay where they are planted they are good for using where a geometric spacing is required. Achillea kellereri is a nectar source for the Checkerspot Butterfly and the Painted Lady Butterfly and is a great addition to your butterfly garden.
