Please remember the following information about Agastache: It is commonly known as giant hyssop or hummingbird mint. It is a genus of herbaceous perennials native to North America, containing about 30 species.
Hybrids of Agastache typically have more vibrant flowers and are more complex in winter than species plants. These hybrid flowers come in various colors, including reds, oranges, pinks, yellows, and whites. Most hybrid plants have dense terminal spikes of tiny tubular flowers with two lips, blooming from mid-summer until fall. These flowers are organized in many-flowered verticillasters (false whorls) atop stiff square stems, clad with opposite pairs of gray-green to medium-green, fragrant leaves that give off an anise or licorice scent. Bees, hummingbirds, and butterflies love the flowers.
One specific variety, 'Poquito Orange,' features dense spikes of orange flowers and is noted for its more compact habit. It grows well in average, medium moisture, well-drained soils in full sun but can also tolerate some light shade. It is essential to ensure proper drainage; it will not perform well in clay soil that retains moisture. Once established, the plants can tolerate some dry soils and heat. Deadhead-spent flowers are recommended. Additional hybrids are typically winter hardy to USDA Zone 6. Plants should be protected in protected areas, like southern exposures, with leaves and flower stems left over winter. Using sandy or gravelly mulch will help protect plants and prevent rot.
