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 summer through fall. That long bloom time, combined with high nectar content, makes this plant highly attractive to bees and butterflies, including the federally-endangered Rusty Patched Bumblebee (see photo). Birds feed on the seeds that follow. The sturdy, sqaure stems support foliage that turns a rich brown and provides upright interest throughout the winter months. No need to try to prounounce the species name, skrof-yew-lar-ee-ih-FOE-lee-ah, just know it's a fantastic pollinator plant that we hope catches on in more native landscapes. It can be cut back in late spring to reduce overall plant height and encourage a bushier appearance. Sensitive to competition, Purple Giant Hyssop requires some habitat disturbance to persist in an area over time. Seeds, photos and description from Prairie Moon Nursery
