Bright, sunshine-yellow flat-topped blooms hover over a tidy clump of fine, aromatic foliage from early through late summer, bringing cheerful, long-lasting color to the front of a sunny border. Little Moonshine is wonderfully easygoing — it loves full sun, asks for very little water once settled in, and shrugs off heat, lean soils, and even the juglone beneath black walnut trees. Butterflies flock to the nectar-rich flower heads and finches nibble the seedheads come fall, yet deer and rabbits consistently leave it untouched. Snip the spent blooms and you’ll coax a second flush of flowers, lovely for fresh-cut bouquets. Its compact, clumping shape suits borders, containers, and pollinator gardens alike, while its dense roots make it a smart pick for stabilizing a sunny slope. With the tough, prairie-born resilience of classic yarrow, it’s a true plant-it-and-enjoy-it perennial.
