This gigantic native wildflower grows up to 6 feet tall and bears spikes of tightly clustered pale yellow flowers. The spicy, licorice-scented foliage is very attractive to birds, butterflies, and bees.
Giant Hyssop grows wild across the central prairie regions of the United States and Canada. Native Americans used the rough, serrated leaves in poultices to relieve poison ivy rash, as well as brewing them for tea. A popular choice for planting in perennial gardens, it attracts bees and butterflies as well as small birds. As a cut flower, it performs very well; in Holland, research and development is under way to produce a hybrid of this variety especially suited for the cut flower industry. Giant hyssop can usually be found growing wild in meadows, along fences, or in deciduous woods and brush.
