From Prairie Moon Nursery:
Anise Hyssop has flower spikes that burst with a myriad of tiny blooms that span the purple spectrum: from soft lavender to rich violet. The blossoms pop open in intervals, providing a long nectar season for bumblebees, hummingbirds, and butterflies; this plant is abuzz with pollinators all summer long! Sturdy and upright, the square stem supports fragrant foliage, which smells like anise or licorice. The undersides of the leaves are white or light gray and flash and wink whenever the wind blows. Makes a fantastic addition in sensory gardens. This plant is easy to grow and often blooms in its first year. It self-sows readily; the new seedlings are quite hardy and can be transplanted easily. Once established, Anise Hyssop is drought tolerant. It is also deer resistant; most mammals dislike the strong scent of the leaves.

Other common names in use: Lavender Hyssop or Blue Giant Hyssop.
