There are lots of types of yarrow that grow well in our gardens and in multiple colors. But the one shown here is my favorite, fernleaf yarrow (Achillea filipendulina), and it is the one that graces my border. While these photos were take elsewhere, mine is really coming into it own after being planted last spring.
Fernleaf Yarrow is a great perennial, and every time I have had it in my garden it has taken time to grow a large clump that will have such a nice display of flowers, as the ones in bloom in the image above. It is tough once it is established, as it is somewhat drought resistant and can tolerate poor soil so long as it will drain. It likes sun, and once the clumps number of blooms start being less each year, it is time to be divided. They are great cut flowers, and the blooms dry well. If you want to keep them in the garden, be sure and remove the flower stalks when they finish blooming.
