A Flowering Herb Garden

Our top 10 picks for adding herbal color to the garden.

Filipendula ulmaria 
Also known as queen-of-the-meadow, this graceful perennial herb produces frothy clusters of creamy white flowers in mid to late summer. The large, dark green leaves grow in creeping clumps; divide plants every two to three years to control their spread. Plants can reach 3 to 4 feet tall in bloom, although they may be shorter if the soil is dry. Zones 3 to 9. 
Purple coneflower 
Echinacea purpurea 
Purple coneflower produces clumps of sturdy stems topped with large, rosy pink, daisylike flowers that have raised, orange-brown centers. Plants bloom from midsummer into fall, especially if you snip off the dead flowers in summer. The blooms of 'Crimson Star' are particularly deep rose-pink. You may also find cultivars with white flowers, such as 'White Swan'. Plants grow 3 to 4 feet tall. Zones 3 to 9.
