Agastache grows best in freely draining gritty soils, where it will be firmly upright in growth; rich, moist soils encourage a more sprawling habit and a decrease in flowering. Plant in a raised bed or amend heavier soils with generous amounts of compost, sand, and gravel for the best overwintering success. A winter mulch of pine needles or stone is best in Northern areas, as they do not harbor much moisture. Then, wait until spring to cut down to further encourage its perennial nature. A pollinator-friendly variety that unfailingly attracts hummingbirds, butterflies, and bees, while the minty, anise-scented foliage is unappealing to deer and rabbits. In their first year of growth, perennials bulk up roots and foliage, blooming more abundantly starting the second year. Self sows.
