Feverfew, Double (Tanacetum parthenium “Flore pleno”)

Perennial
Branched sprays of ½” double white daisies like large baby’s breath flowers. Dark green, aromatic foliage has a long history of treating fevers and headaches. Much used today by herbalists for migraines. Good cut flower, very pretty in bouquets.
To grow: Sow seed in early spring in sun or shade. Self-sows readily; once it’s established, the garden will never be without it.
