Hyssop- Purple Giant (Agastache scrophulariifolia)
Purple Giant Hyssop sets soft plumes of the palest purple flowers that top out at 6 feet, soaring above most other plants in the garden. The individual blossoms open over a period of several weeks in the fall. That long bloom time, combined with high nectar content, makes this plant highly attractive to bees and butterflies. The sturdy, sqaure stems support highly fragrant foliage and turn a rich brown and provide upright interest throughout the winter months.
