Unfortunately, this photo doesn't do justice to Anthemis tinctoria, or Golden Marguerite (the flowers aren't nearly this blurry), one of my favorite summer garden perennials.  These small, but colorful, yellow daisies are abundant for most of the summer if you keep them deadheaded, but what I like most is the fern-like foliage.  Together, they make a wonderful garden plant and one I have not been without for many years. Anthemis tinctoria grows from two to three feet; if it gets a little sprawling for you, just give it a good pruning to keep it in check.  Anthemis tinctoria is not known for being a long-lived perennial, but it will often reseed, and it makes up for its lack of longevity by being a workhorse in the flower department and being easy to please.  Zones 3-8.  Quarts.
