Also called floss flower, Ageratum is an annual with pink, white, violet or blue blooms. Pressing the flowers flattens them and tends to make the colors fade, so dry them in a preservative (a desiccant) instead. Lengthen the short stems with floral wire, if desired. Then remove the foliage and put the flowers facedown in the desiccant for 2 or 3 weeks. Check periodically and remove them when they’re dry, but before they become brittle.

‘Everest Blue’ is a tall ageratum that grows 20 to 26 inches tall. Developed for the cut flower market, it makes a terrific addition to planting beds, cottage gardens and large containers. Japanese beetles tend to avoid the hairy, quilted leaves of ageratum, but may rarely munch on the blooms.
