Agastache rupestris

Rock anise hyssop

Licorice Plant, so nicknamed by Dr. Allan Armitage, of the University of Georgia for the deliciously scented foliage - mmmm - let your customers rub it! Striking warm rosy orange verticillate flowers with silvery foliage sets this plant apart. It is upright, somewhat shrubby and quite cold tolerant. This is an outstanding plant, in flower from June until killing frost. Championed by Panayoti Kelaidis of the Denver Botanic Gardens.

Rock anise hyssop Interesting Notes

Tom Peace, plantsman extraordinare, shared this fabulous Agastache with me last summer while attending the Perennial Plant Association meeting in Denver. In mid-summer hummingbirds are drawn like magnets to the multiple spikes of coral flowers that appear in profusion atop 3' plants. Touch the foliage and scents of licorice, root beer or mint fill the air. Indigenous to West Texas and Mexico, this Agastache is grown successfully by Tom in Texas and Denver. "In Texas, it grows a little shorter and tighter, with coral spikes of 2' on 10" wide plants," he reports. It performed beautifully in NC as well, throwing blooms for weeks throughout July and August. Plant in lean, well-drained soil, in full sun and enjoy. It quickly became "my favorite find" in Denver.

The striking, rosy-orange, verticillate flowers and gray foliage provide a lovely wildflower to add color to the garden. One of the hardiest of the native hyssops, it has been used to incorporate cold tolerance to a number of hybrids. The flower is unusual, and the flowering persists for at least 8 weeks. The best part of these plants is the fragrance of the foliage. People keep coming back to get their sniff, then bring their friends to get theirs. Full sun and well-drained soils are necessary.
