This is the Common European Feverfew, which grows about 2 ft. high, and has deeply cut, lobed and toothed leaves, and white flowers with yellow centres, in summer. The double variety (flore pleno) is grown in some market gardens for cut flower. There are other forms with double flowers, the best being eximia, pure white, rounded; grandiflora, and pyramidalis. The plants are best raised from cuttings sheltered in a cold frame during the winter months, and planted out in March or April. They may also be increased by dividing the tufts. Matricaria inodora flore pleno (which see) is a closely related plant.
