ag-ah-STAK-ee roo-GO-sah
Genus:  Agastache
This 4-foot-tall and 18-ich-wide, bushy perennial, very similar to the more common anise hyssop ( Agastache foeniculum ) has strongly mint-and-licorice-scented leaves and short spikes of lavender-blue flowers from midsummer to early fall. Unlike most agastaches, both of these species can tolerate more moisture and humity, making them highly suited to climates outside the arid west.
Noteworthy Characteristics:  Attractive to bees, butterflies, and hummingbirds
Care:  Provide full sun and moist, well-drained soil.
Propagation: 

 Divide clumps in spring

Problems: 

 Occasional downy mildew may occur.
