Sunset Hyssop Attributes

This plant produces tubular flowers in a range of salmon-orange hues. Held by its purple calyxes, the flowers last throughout the summer. In addition to its beauty, the flower has a sweet, fragrant aroma reminiscent of root beer. For that reason, the Sunset Hyssop is often called the “root beer hyssop plant” or the “licorice mint hyssop.”

The Sunset Hyssop is on full display from early to late summer. The flowers emulate a sunset with bronze colors that feature hints of yellow and orange. You can even see streaks of pink and magenta along the margins of the plant. Throughout the summer, more flowers will emerge. This hyssop blooms heavily in August, and you can enjoy those flowers into the autumn. It will form an upright clump of slender, wiry, and branched stems that can reach heights ranging from 18 to 30 inches tall.

The Sunset Hyssop is native to the western part of the United States. It is also an attractive plant for hummingbirds. When the hyssop is in full bloom, these creatures enjoy drinking the sweet nectar of the plant.
