Flat clusters of tiny red flowers sit above ferny, aromatic foliage in New Vintage Red, a yarrow that keeps blooming through summer heat. Full sun and lean, well-drained soil suit it, and rich ground will only make it flop.

Clay is the enemy here, so amend the bed or plant on a slope where water drains away quickly. Once established it tolerates drought, and deer tend to leave it alone. Cut the flower heads for arrangements or hang them to dry, and they hold their color well.
