A Flowering Herb Garden

Tanacetum parthenium 

Feverfew may look delicate, but it's a sturdy, easy-to-grow herb that blooms from early summer to early fall. The white-petaled, yellow-centered flowers look like tiny daisies. Pinching off the spent flowers can extend the bloom season, and it will reduce the number of self-sown seedlings. You can also cut the whole plant to the ground after bloom for a flush of new growth. Plants grow about 2 feet tall. Zones 4 to 9. 
 

Joe-Pye weed 

Eupatorium purpureum 

Tall Joe-Pye is the glory of the late summer garden. Its domed clusters of rosy pink to light purple flowers tower over shorter herbs, with sturdy stalks in multistemmed clumps. The flowers attract butterflies as well as lots of attention from garden visitors. 'Atropurpureum' also offers deep purple stems. 'Album' has white flowers. Plants are slow to emerge in spring, so place markers by the clumps. Stems reach 6 to 8 feet tall in bloom. Zones 3 to 8.
