|These bushy perennials look like their cousins, mint and salvia. Once established, they thrive in hot, dry sites, offering a late-summer display of flower spikes in soft purples, blues, or yellows. Some varieties are more tender and need the shelter of a south- or west-facing wall. Hardier varieties are Agastache foeniculum, Agastache rugosum, and Agastache urticofolium. Drought-tolerant and require good drainage. Grow many varieties, such as Agastache mexicana, from seed, divide established plants in early spring, or take root cuttings from young, soft stems. Watch for mildew in hot dry summers.
One of the hardier Agastaches, this native American plant offers a delicious licorice-like fragrance. Spikes of showy, lavender blue fit in the perennial border and herb garden.
