This is a great plant for hot, dry, sunny climates. Well-drained soil is a must, especially in the winter. This plant will not tolerate heavy clay soil but grows well in average to light soil with low to medium moisture levels. In the sandy soil of our zone 5b trial garden, this variety has overwintered with flying colors for the past two years. Even so, it's officially listed as a zone 6 perennial so some winter protection might be required in your zone. No serious pest or disease problems have been reported with this plant.
