A delicate-looking perennial with feathery foliage and small daisy-like white or pale yellow flowers. Traditionally used in herbal medicine and attractive to pollinators.

Why grow it

Feverfew establishes readily in poor to moderately fertile soil where many ornamental perennials struggle, making it useful for filling gaps in marginal garden areas. Its fine foliage and prolific flowering provide textural contrast to coarser plants, and it self-seeds moderately, reducing replanting labor. As a long-season nectar source (summer through fall), it supports pollinators more reliably than many daisy-family ornamentals that peak earlier in the year.

Watch out for

Feverfew can spread vigorously by seed in favorable conditions and may become weedy in small or intensively managed gardens; deadheading or cutting before seed set helps contain it. Some gardeners report skin sensitivity when handling the foliage repeatedly during harvest or pruning, so brief contact is typically fine but extended work may warrant gloves. It prefers well-drained soil and can decline in persistently wet conditions, particularly over winter.
