Feverfew/Matricaria (Chrysanthemum parthenium) is a perennial often used in the garden to repel insects, but florists cannot resist their filler-flower talents and citrus scent. It used to be that all feverfew options looked like tiny daisy sprays on long stems, but now there are a half a dozen different types with and without the daisy look. Magic Single has the traditional daisy look; one or two layers of bright white petals around a gold center. Snow Ball and Virgo are all-white pompom versions. Sunny Ball sports only bright yellow buttons. Tetra White has many layers of white surrounding small orange centers in contrast to the Magic Lime Green which is almost all soft yellow centers and bears only a small halo of white.
Feverfew, like calendula and yarrow, needs a few drops of bleach (or a bleach tablet) to get a 7-day vase life. On the plus side, it dries well for wreaths and everlasting bouquets. Just bundle the stems and turn them upside down in a cool, dark, dry place.
