Sonoran Sunset Hyssop
Sonoran Sunset is a selection of a native perennial flower that grows in New Mexico and Texas. It is wonderfully adapted to hot, dry locations.
The leaves are intensely fragrant and has large deep pink flowers on a compact plant. This is an excellent plant to attract hummingbirds and hawk moths to your yard.
Compared to many other hyssops, Sonoran Sunset has showier flowers. It blooms longer and earlier, too.
In Colorado Springs, its winter survivability is not as reliable as sunset hyssop, Agastache rupestris.

Performance
At the Demonstration Garden, we've tested Sonoran Sunset in a variety of locations. It grows well in hot, sunny sites on the south side of the building. It has also done well in part shade locations, too.
Although some plants have died after transplanting, it has such beautiful flowers that attract hummingbirds and hawk moths that it's worth losing a few plants to get several established.
Sonoran Sunset hyssop has survived the winter much better when we've cut it back in spring rather than in fall.
Maintenance
Don't cut back in fall. To increase the chance of winter survival, cut dead stems to ground level only in early spring after new leaves have appeared at base of plant.
See in a landscape
This renovation eliminated all bluegrass from the plan, and instead took advantage of plants that offered a variety of color and texture. This yard had a few different challenges when considering a new landscape: slope, deer, western exposure and low water and maintenance needs. The rock chosen for this yard is slightly angular so it doesn't roll downhill easily, the plants are selected for deer resistance and heat loving which is necessary for a west facing yard that has a heat-holding rock mulch. In fact, many of these plants actually prefer rock mulch rather than wood mulch that may hold too much water too near the plant. And finally, the landscape is watered with drip irrigation to make best use of water. With drip irrigation, water is applied only where the plants need it, and not in unnecessary areas where only weeds might grow, saving time with maintenance.
