Agastache, also known as Hummingbird Mint, is the perfect choice for hot, dry, sunny climates. Properly sited plants tolerate winter better, which is especially important for colder zones. Well-drained soil is a must, especially in winter. Will not tolerate heavy clay or overly rich soils. Leave stems over winter, then cut back hard in mid-spring. Drought tolerant, deer resistant, and attracts butterflies and hummingbirds.
