A genus of aromatic plants with purple or pink flowers, commonly called giant hyssop or horsemint.
From Greek 'aga' (much) and 'stachys' (ear of grain, or by extension, spike-like flower cluster), literally 'many-spiked' referring to the flower structure.
Agastache is beloved by hummingbirds and bees, and Native Americans used it for tea and medicine for centuries—then modern gardeners rediscovered it as a 'new' ornamental plant, which is why it's now called a 'new perennial.'
