Tanacetum parthenium, or Chrysanthemum parthenium, brightens the garden with profusions of cheery daisy-like blooms from midsummer through early fall. Feverfew has been grown for making home remedies for centuries, and remains in common use today. These fast-growing mounding perennials spread readily and can cover a large area over a period of several years. Feverfew does need to be cut back in the fall for the sake of its overall health and vigor.
Use clean, sharp scissors to harvest leaves of mature feverfew plants for home remedies in the morning after the dew has dried during the growing season. Harvest these plants before they begin blooming.
Cut flowers freely with clean, sharp scissors for your indoor arrangements from midsummer until fall.
Deadhead spent feverfew blooms throughout the growing season to prevent the plants from reseeding themselves excessively.
Use clean, sharp shears to cut the feverfew plants back to ground level after they've died back for the season.
Clean up and dispose of all dead plant materials around your feverfew. This will go a long way toward preventing unwanted pests and diseases from over-wintering in the area.
Apply a 2- to 4-inch layer of organic mulch just before the first predicted frost in your area to protect feverfew from brutal winters. Remove the mulch in the spring.
