I have grown Costmary for many years in my herb garden, and I love this perennial herb for lots of reasons:  it has an addictive, fresh minty fragrance; its large, bright green leaves bespeak springtime; it has pretty little yellow button flowers in summer; and, most of all,  I just like the sound of the name, "Costmary."  The leaves can be used for tea and, if dried, for adding to drawers and cupboards.  I once pressed a large leaf in a book, and it made the nicest bookmark I have ever had.  I didn't know then that a common name for Costmary is "Bible Leaf" because of its use as fragrant bookmarks.  Costmary may need to be given a little sprucing up from time to time to keep it tidy, but other than that, it's a joy to have.  Sun.  Zones 6-9.  Quarts.

Growing to about three feet, Tansy has green, fern-like foliage and bright yellow button flowers. This perennial herb also has a definite scent, which explains its insect repellent properties that are relied on all over the world. Tansy has been used medicinally, for dying, in dried arrangements, and as a companion plant for cucumbers, squash, and roses. Tansy, a European native, grows in Zones 4-8. (Illustration by C.A.M.
